Stem Cell Treatments – Brain and Spinal Cord

By Sykes24Tracey

Because stem cells have the potential to generate cells designed to replace or repair cells damaged by spinal cord injury, advocates of stem cell research and treatment believe that the benefits far outweigh the negative aspects. Opponents of this research and treatment, however, typically bring up the issue of embryonic stem cells, which are harvested from embryos and fetal tissue. Accordingly, they feel the use of these embryonic stem cells is not moral or ethical. Because stem cells are harvested from embryos and fetal tissue, they feel it is not moral or ethical. Secondly, opponents are concerned about the health and safety of the participants in human stem cell research trials. It is important to note that non-embryonic stem cells, called somatic or adult stem cells, have recently been identified in various body tissues including brain, bone marrow, blood vessels, and various organ tissues.

Lets talk about how stem cell research could possibly impact spinal cord injury. Stem cell research came on the scene in 1998, when a group of scientists isolated pluripotent stem cells from human embryos and grew them in a culture. Since then, specialists have discovered that stem cells can become any of the 200 specialized cells in the body, giving them the ability to repair or replace damaged cells and tissues. While not yet known to have the diversification potential of embryonic stem cells, adult somatic cells act similarly and are generating excitement in the research and medical community.

When all is said and done, could stem cell treatment be the miracle cure for spinal cord injury and paralysis? Well, we dont really know. Because of all of the controversy, much of the evidence that shows stem cells can be turned into specific cells for transplantation involves only mice, whose cells are significantly different than human cells. Nevertheless, some initial research points to promising results. One hurdle that remains to be cleared is whether an immune response would reject a cellular transplant.

Ultimately, no one yet knows the extent to which stem cell treatment could help spinal cord injury and paralysis. Scientists remain hopeful, but currently there just hasnt been enough research done to substantiate any particular result. Additional research needs to be done before we have more definitive answers.

Again, we just dont know. Much of the answer depends upon whether the political process and moral debate continues to limitand put the hold onthe amount of research done. At this point its impossible to say for sure whenor even ifstem cells will be useful in the treatment of paralysis.

Syrinx of the Spinal Cord or Brain Stem – Neurologic Disorders – Merck Manuals …

By raymumme

A syrinx is a fluid-filled cavity within the spinal cord (syringomyelia) or brain stem (syringobulbia). Predisposing factors include craniocervical junction abnormalities, previous spinal cord trauma, and spinal cord tumors. Symptoms include flaccid weakness of the hands and arms and deficits in pain and temperature sensation in a capelike distribution over the back and neck; light touch and position and vibration sensation are not affected. Diagnosis is by MRI. Treatment includes correction of the cause and surgical procedures to drain the syrinx or otherwise open CSF flow.

Syrinxes usually result from lesions that partially obstruct CSF flow. At least half of syrinxes occur in patients with congenital abnormalities of the craniocervical junction (eg, herniation of cerebellar tissue into the spinal canal, called Chiari malformation), brain (eg, encephalocele), or spinal cord (eg, myelomeningocele). For unknown reasons, these congenital abnormalities often expand during the teen or young adult years. A syrinx can also develop in patients who have a spinal cord tumor, scarring due to previous spinal trauma, or no known predisposing factors. About 30% of people with a spinal cord tumor eventually develop a syrinx.

Syringomyelia is a paramedian, usually irregular, longitudinal cavity. It commonly begins in the cervical area but may extend downward along the entire length of the spinal cord.

Syringobulbia, which is rare, usually occurs as a slitlike gap within the lower brain stem and may disrupt or compress the lower cranial nerve nuclei or ascending sensory or descending motor pathways.

How Adipose Stem Cell Technology Develops Spinal Cord Injury Treatment

No matter where they may naturally be found in the body, Adult Stem Cells are like electricity. They are pure potential. When properly stimulated, stem cells become whatever type of cell the body needs: bone, blood, cartilage, muscle, nerve, and more. The results of studies like those published on CellTherapyJournal.org and reported on at MedScape.com state that stem cells, particularly Adipose-Derived Stem Cells, have great potential in the development of Stem Cell Therapy for Spinal Cord Injury.*

When a Spinal Cord Injury occurs, the resulting inflammation releases inhibiting factors that ultimately cause the fibers of nerve cells to retract. Scar tissue develops, effectively preventing a bridge to be formed across the area of injury. This, in essence, is what prevents healing and causes the debilitating effects after injury. But research has shown that Adult Stem Cells, particularly Adipose-Derived Stem Cells, have the potential for bridging the gap. Additionally, stem cells might excrete substances that reduce damaging inflammation. Already, trials involving Spinal Cord Injury Therapy via stem cells are producing remarkable effects.

Studies from around the world are reporting exciting results, from trial subjects undergoing stem cell therapy for spinal cord injury who regain the capacity to feel light touch to some who were able to walk for at least an hour with the aid of a walker. An improvement in bladder and bowel control was also reported.

Where To Find Stem Cell Therapy In The U.S.

Stem Cells & Spinal Cord Injuries – sci-info-pages.com

By Dr. Matthew Watson

Stem cell therapy can be defined as a part of a group of new techniques, or technologies that rely on replacing diseased or dysfunctional cells with healthy, functioning ones. These new techniques are being applied experimentally to a wide range of human disorders, including many types of cancer, neurological diseases such as Parkinson's disease and ALS (Lou Gehrig's disease), spinal cord injuries, and diabetes.

Coalition for the Advancement of Medical ResearchThe Coalition for the Advancement of Medical Research (CAMR) is comprised of nationally-recognized patient organizations, universities, scientific societies, foundations, and individuals with life-threatening illnesses and disorders, advocating for the advancement of breakthrough research and technologies in regenerative medicine - including stem cell research and somatic cell nuclear transfer - in order to cure disease and alleviate suffering.

Portraits of HopeVolunteer group of patients and their families and friends who believe that stem cell research has the potential to save the lives of those afflicted by many medical conditions, including spinal cord injury. Purpose is to show the faces and recount the stories of people who have such illnesses and present these portraits to federal and state legislators in request for government support.

Paraplegic breakthrough using adult stem cells – WND

By raymumme

In an apparent major breakthrough, scientists in Korea report using umbilical cord blood stem cells to restore feeling and mobility to a spinal-cord injury patient.

The research, published in the peer-reviewed journal Cythotherapy, centered on a woman had been a paraplegic 19 years due to an accident.

After an infusion of umbilical cord blood stem cells, stunning results were recorded:

The patient could move her hips and feel her hip skin on day 15 after transplantation. On day 25 after transplantation her feet responded to stimulation.

Umbilical cord cells are considered adult stem cells, in contrast to embryonic stem cells, which have raised ethical concerns because a human embryo must be destroyed in order to harvest them.

The report said motor activity was noticed on day 7, and she was able to maintain an upright position on day 13. Fifteen days after surgery, she began to elevate both lower legs about one centimeter.

The studys abstract says not only did the patient regain feeling, but 41 days after stem cell transplantation, testing also showed regeneration of the spinal cord at the injured cite and below it.

The scientists conclude the transplantation could be a good treatment method for paraplegic patients.

Bioethics specialist Wesley J. Smith, writing in Lifesite.com, expressed enthusiasm about the apparent breakthrough, but also urged caution.

We have to be cautious, said Smith, a senior fellow at the Seattle-based Discovery Institute and a special consultant to the Center for Bioethics and Culture. One patient does not a treatment make.

The authors of the study note, writes Smith, that the lamenectomy the patient received might have offered some benefit.

But still, this is a wonderful story that offers tremendous hope for paralyzed patients, he said.

The fact that the patient has a very old injury, Smith added, makes the results even more dramatic.

Smith said he has known about the study for some time, but because I didnt want to be guilty of the same hyping that is so often engaged in by some therapeutic cloning proponents, I waited until it was published in a peer reviewed journal.

Like most breakthroughs using adult stem cells, this one has been completely ignored by the U.S. mainstream media, Smith pointed out.

Can you imagine the headlines if the cells used had been embryonic? he asked.

Adult Stem Cell Success Story | Spinal Cord Injury | SCRF

By raymumme

(May, 2010) If there was ever a woman on a mission, its Laura Dominguez. Doctors once told her shed never walk again. And while shes not ready to run a marathon, shes already proving them wrong, with the best yet to come.

An oil spill on a San Antonio freeway is blamed for the car crash that sent Laura and her brother directly into a retaining wall one summer afternoon in 2001. Laura was just 16 years old at the time and the crash left her completely paralyzed from the neck down. Surgeons say she suffered whats known as a C6 vertebrae fracture that severely damaged her spinal cord.

I refused to accept their prognosis that I never would walk again and began searching for other options, says Laura. After stays in several hospitals for nearly a year, Laura and her mother relocated to San Diego, CA so that she could undergo extensive physical therapy. While in California, they met a family whose daughter was suffering from a similar spinal cord injury. They were also looking for other alternatives to deal with spinal cord injuries.

After extensive research and consultations with medical experts in the field of spinal cord injuries, they decided to explore a groundbreaking new surgical procedure using adult stem cells pioneered by Dr. Carlos Lima of Portugal.

The surgery involved the removal of tissue from the olfactory sinus area at the back of the nose--and transplanting it into the spinal cord at the injury site. Both procedures, the harvesting of the tissue and the transplant, were done at the same time. Laura was the tenth person in the world and the second American to have this procedure done and was featured in a special report by PBS called Miracle Cell.(Link to Miracle Cell (PBS) Episode)

Following the surgery she returned to California where she continued with the physical therapy regimen, then eventually returned home to San Antonio. Upon her return home, an MRI revealed her spinal cord was beginning to heal. Approximately 70% of the lesion now looked like normal spinal cord tissue. More importantly to Laura, she began to regain feeling in parts of her upper body and within six months of the surgery regained feeling down to her abdomen.

Improvements in sensory feelings have continued until the present time. She can feel down to her hips, and has regained feeling and some movement in her legs. Lauras upper body has gained more strength and balance and one of the most evident improvements has been her ability to stand and remain standing, using a walker, and with minimal assistance. When she stands she can contract her quadriceps and hamstring muscles.

Every week it seems Im able to do something new, something different that I hadnt done the week before, says Laura.

Now Lauras story is poised to take a new, potentially groundbreaking turn. In the Fall of 2009, she traveled again to Portugal where adult stem cells were extracted from her nose for culturing. As this story is written, she is preparing to fly back to Portugal where scar tissue at her injury site will be removed and her own adult stem cells injected in the area of her original wound.

The Laura Dominguez story is not complete. The next chapter may or may not yield the results she seeksbut no one can deny the determination and courage of Laura. For her part, she has one goal in mind: I will walk again.

We shall update this site and keep you informed on her progress.

Spinal cord compression – Canadian Cancer Society

By Dr. Matthew Watson

The spinal cord is a column of nerve tissue. It runs from the brain stem down the back through the centre of the vertebrae, which are the bones of the spinal column. The nerves in the spinal cord carry messages (electrical signals) between the brain and the rest of the body. Spinal cord compression (also called cord compression) is a problem that occurs when something, such as a tumour, puts pressure on the spinal cord. The pressure causes swelling and means that less blood can reach the spinal cord and nerves.

Spinal cord compression is a serious condition that needs to be treated right away.

Spinal cord compression can be caused by any condition that puts pressure on the spinal cord. It can happen if the vertebrae are damaged or collapse. It can also develop if a tumour puts pressure on the spinal cord.

The most common cause of spinal cord compression in people with cancer is metastasis to the spine. About 60%70% of metastases to the spine occur in the middle part of the back, which is called the thoracic spine. About 20%30% of metastases happen in the lower back, or lumbosacral spine. Only about 10% of metastases happen in the upper back or neck area, which is called the cervical spine. About 30% of people with metastasis to the spine will have metastases in more than one area of the spine.

Any type of cancer can spread to the spine, but it is more common with the following cancers:

Symptoms of spinal cord compression can vary. They may be mild at first or pain may be the only symptom. As the tumour puts more pressure on the spine, the symptoms become worse and more serious.

Pain in the back or neck is a common symptom. It may feel like a band around the chest or abdomen. It can radiate, or spread out, over the lower back and into the buttocks or legs. It may also spread down the arms. The pain may be worse when you lie down.

Other symptoms of spinal cord compression include:

Your doctor will try to find the cause of spinal cord compression. This usually includes physical and neurological exams that include questions and tests to check brain, spinal cord and nerve function. Your doctor will also check your coordination and how well your muscles and reflexes are working.

Spinal cord compression is usually diagnosed by the following imaging tests:

If a centre doesnt have MRI or CT scans, the doctor may order myelography. During this procedure, an x-ray is taken after injecting a dye into the spinal canal. The spinal canal is the hollow space in the spinal column that contains the spinal cord.

Find out more about these tests and procedures.

Spinal cord compression needs to be treated right away to try to prevent permanent damage to the spinal cord. The goal of treatment is to give you the best quality of life possible. Treatments are used to:

You may be given one or more of the following treatments. Your doctor may also order physical therapy or other rehabilitation after treatment to help you maintain and improve your ability to move.

Corticosteroids are drugs that reduce swelling and lower the bodys immune response. They are used to quickly lower swelling and pressure around the spinal cord. They can also quickly relieve pain.

The healthcare team will usually start corticosteroids right away if they think you have cord compression. The dose is gradually lowered and then stopped if symptoms improve or if you start other treatments.

External beam radiation therapy is the most common treatment for spinal cord compression. It is a type of radiation therapy that uses a machine outside the body to direct radiation at a tumour and surrounding tissue. It is used to shrink a tumour pressing on the spinal cord.

You will start external beam radiation therapy as soon as possible after your doctor diagnoses cord compression. It is usually given as a short-course treatment, which means it is given for a short period of time. Treatments for most types of tumours can vary from a single treatment to daily treatments for 2 weeks. If you have lymphoma or multiple myeloma, you may need radiation therapy for up to 4 weeks. If you need surgery, radiation therapy may be given after surgery.

Surgery may be offered if the tumour doesnt respond to radiation therapy or if you already had radiation therapy. But surgery is an option for only a small number of people. Whether or not you can have surgery depends on the type of tumour, where the tumour is and how unstable the spine may be. Other factors include whether or not the specialized equipment and a trained neurosurgeon are available in your area and the overall prognosis of the cancer.

Surgery is used to remove as much of the tumour as possible. It is also used to stabilize the spine and relieve pressure within the spine.

The surgeon may remove parts of a vertebra to remove a tumour or relieve pressure on the spinal cord. Removing parts of a vertebra will not weaken the spine. The surgeon may place steel pins or rods to help stabilize the spine.

Your healthcare team may use drug therapy to treat the tumour. The type of drugs given will depend on the type of cancer. Chemotherapy may be used for certain types of cancer such as non-Hodgkin lymphoma (NHL) or lung cancer. Hormonal therapy and chemotherapy may be given after radiation therapy or surgery for other types of cancer such as breast or prostate cancer.

If your healthcare team thinks that you are at risk of developing spinal cord compression, they may prescribe bisphosphonates. These drugs stop the body from breaking down bone. They also help strengthen bones. Bisphosphonates are used to help protect bones in the spinal column against the effects of some cancers. Find out more about bisphosphonates.

Levels of Spinal Cord Injury – Brain and Spinal Cord

By NEVAGiles23

Basic Spinal Cord Anatomy

To understand this confusion and what you are actually being told when your injury is described as being at a certain level, it is necessary to understand basic spinal anatomy. The spine and the spinal cord are two different structures. The spinal cord is a long series of nerve cells and fibers running from the base of the brain to shortly above the tailbone. It is encased in the bony vertebrae of the spine, which offers it some protection.

The spinal cord relays nerve signals from the brain to all parts of the body and from all points of the body back to the brain. Part of the confusion regarding spinal cord injury levels comes from the fact that the spine and the spinal cord each are divided into named segments which do not always correspond to each other. The spine itself is divided into vertebral segments corresponding to each of the vertebrae.

The spinal cord is divided into neurological segmental levels, meaning that the focus is on what part of the body the nerves from each section control. The spine is divided into seven neck (cervical) vertebrae, twelve chest (thoracic) vertebra, five back (lumbar) vertebrae, and five tail (sacral) vertebrae. The segments of the spine and spinal cord are designated by letters and numbers; the letters used in the designation correspond to the location on the spine or the spinal cord. For example:

The spinal cord segments are named in the same fashion, but their location does not necessarily correspond to the spinal segments location. For example:

The spinal cord is responsible for relaying the nerve messages that control voluntary and involuntary movement of the muscles, including those of the diaphragm, bowels, and bladder. It relays these messages to the rest of the body via spinal roots which branch out from the cord.

The spinal roots are nerves that go through the spines bone canal and come out at the vertebral segments of the spinal cord. Bodily functions can be disrupted by injury to the spinal cord. The amount of the impairment depends on the degree of damage and the location of the injury.

The head is held by the first and second cervical segments. The cervical cord supplies the nerves for the deltoids, biceps, triceps, wrist extensors, and hands. The phrenic nucleus (a group of cell bodies with nerve links to the diaphragm) is located in the C3 cord.

The thoracic vertebral segments compose the rear wall of the ribs and pulmonary cavity. In this area, the spinal roots compose the between the ribs nerves (intercostal nerves) which control the intercostal muscles.

The spinal cord does not travel the entire length of the spine. It ends at the second lumbar segment (L2). Spinal roots exit below the spinal cords tip (conus) in a spray; this is called the cauda equine (horses tail). Damage below the L2 generally does not interfere with leg movement, although it can contribute to weakness.

In addition to motor function, the spinal cord segments each innervate different sections of skin called dermatomes. This provides the sense of touch and pain. The area of a dermatome may expand or contract after a spinal cord injury.

The differences between some of the spinal vertebral and spinal cord levels have added to the confusion in developing a standardized rating scale for spinal cord injuries. In the 1990s, the American Spinal Cord Association devised a new scale to help eliminate ambiguities in rating scales. The ASIA scale is more accurate than previous rating systems, but there are still differences in the ways various medical specialists evaluate an SCI injury.

Dr. Wise Young, founding director of Rutgers W. M. Keck Center for Collaborative Neuroscience explains that usually neurologists (nerve specialists) will rate the level of injury at the first spinal segment level which exhibits loss of normal function; however, rehabilitation doctors (physiatrists) usually rate the level of injury at the lowest spinal segment level which remains normal.

For example, a neurologist might say that an individual with normal sensations in the C3 spinal segment who lacks sensation at the C4 spinal segment should be classified as a sensory level C4, but a physiatrist might call it a C3 injury level. Obviously, these differences are confusing to the patient and to the patients family. People with a spinal cord injury simply want to know what level of disability they will have and how much function they are likely to regain. Adding to the confusion is the debate over how to define complete versus incomplete injuries.

For many years, a complete spinal cord injury was thought of as meaning no conscious sensations or voluntary muscle use below the site of the injury; however, this does not take in to account that partial preservation of function below the injury site is rather common. This definition of a complete injury also failed to take into account the fact that may people have lateral preservation (function on one side).

In addition, a person may later recover a degree of function, after being labeled in the first few days after the injury as having a complete injury. In 1992, the American Spinal Cord Association sought to remedy this dilemma by coming up with a simple definition of complete injury.

According to the ASIA scale, a person has a complete injury if they have no sensory or motor function in the perineal and anal region; this area corresponds to the lowest part of the sacral cord (S4-S5). A rectal examination is used to help determine function in this area. The ASIA Scale is classified as follows:

At this point, if you are a patient with a spinal cord injury or the family member of a spinal cord injury patient you may be more confused than ever. How do these ratings apply to the daily life of someone with a spinal cord injury? A brief overview of the basic definitions may help.

This is the greatest level of paralysis. Complete C1-C4 tetraplegia means that the person has no motor function of the arms or legs. He or she generally can move the neck and possibly shrug the shoulders. When the injury is at the C1-C3 level, the person will usually need to be on a ventilator for the long-term; fortunately, new techniques may be able to reduce the need for a ventilator.

A person whose injury is at the C4 level usually will not need to use the ventilator for the long-term, but will likely need ventilation in the first days after the injury. People with complete C1-C4 quadriplegia may be able to use a power wheelchair that can be controlled with the chin or the breath. They may be able control a computer with adaptive devices in a similar fashion and some can work in this way. They can also control light switches, bed controls, televisions and so with the help of adaptive devices. They will require a caregivers assistance for most or all of their daily needs.

People with C5 tetraplegia can flex their elbows and with the help of assistive devices to help them hold objects, they can learn to feed and groom themselves. With some help they can dress their upper body and change positions in bed. They can use a power wheelchair equipped with hand controls and some may be able use a manual wheelchair with grip attachments for a short distance on level ground.

People with C5 will need to rely on caregivers for transfers from bed to chair and so forth, and for assistance with bladder and bowel management, as well as with bathing and dressing the lower body. Adaptive technology can help these people be independent in many areas, including driving. People with C5 tetraplegia can drive a vehicle equipped with hand controls.

People with C6 tetraplegia have the use both of the elbow and the wrist and with assistive support can grasp objects. Some people with C6 learn to transfer independently with the help of a slide board. Some can also handle bladder and bowel management with assistive devices, although this can be difficult.

People with C6 can learn to feed, groom, and bath themselves with the help of assistance devices. They can operate a manual wheelchair with grip attachments and they can drive specially adapted vehicles. Most people with C6 will need some assistance from a caregiver at times.

People with C7 tetraplegia can extend the elbow, which allows them greater freedom of movement. People with C7 can live independently. They can learn to feed and bath themselves and to dress the upper body. They can move in bed by themselves and transfer by themselves. They can operate a manual wheelchair, but will need help negotiating curbs. They can drive specially-equipped vehicles. They can write, type, answer phones, and use computers; some may need assistive devices to do so, while others will not.

People with C8 tetraplegia can flex their fingers, allowing them a better grip on objects. They can learn to feed, groom, dress, and bath themselves without help. They can manage bladder and bowel care and transfer by themselves. They can use a manual wheelchair and type, write, answer the phone and use the computer. They can drive vehicles adapted with hand controls.

People with T1-T12 paraplegia have nerve sensation and function of all their upper extremities. They can become functionally independent, feeding and grooming themselves and cooking and doing light housework. They can transfer independently and manage bladder and bowel function. They can handle a wheelchair quite well and can learn to negotiate over uneven surfaces and handle curbs. They can drive specially adaptive vehicles.

People with a T2-T9 injury may have enough torso control to be able to stand with the help of braces and a walker or crutches. People with a T10-T12 injury have better torso control than those with a T2-T9 injury, and they may be able to walk short distances with the aid of a walker or crutches.

Some can even go up and down stairs; however, walking with such an injury requires a great deal of effort and can quickly exhaust the patient. Many people with thoracic paraplegia prefer to use a wheelchair so that they will not tire so quickly.

People with sacral or lumbar paraplegia can be functionally independent in all of their self-care and mobility needs. They can learn to skillfully handle a manual wheelchair and can drive specially equipped vehicles. People with a lumbar injury can usually learn to walk for distances of 150 feet or longer, using assistive devices. Some can walk this distance without assistance devices. Most rely on a manual wheelchair when longer distances must be covered.

There are many other functional scales besides the ASIA scale, but it is the most frequently used. Neurologists find the NLOI (the Neurological level of injury) scale helpful; it is a simply administered test of motor function and range of motion. The Function Independence Measure (FIM) evaluates function in mobility, locomotion, self-care, continence, communication, and social cognition on a 7-point scale.

The Quadriplegic Index of Function (QIF) detects small, clinically significant changes in people with tetraplegia. Other scales include the Modified Barthel Index, the Spinal Cord Independence Measure (SCIM), the Capabilities of Upper Extremity Instrument (CUE), the Walking Index for SCI (WISCI), and the Canadian Occupational Performance Measure (COPM).

Stories of Hope: Spinal Cord Injury | California’s Stem …

By Sykes24Tracey

Espaol

Katie Sharify had six days to decide: would she let her broken body become experimental territory for a revolutionary new approacheven if it was unlikely to do her any good? The question was barely fathomable. She had only just regained consciousness. A week earlier, she had been in a car crash that damaged her spine, leaving her with no sensation from the chest down. In the confusion and emotion of those first few days, the family thought that the treatment would fix Katie's mangled spinal cord. But that was never the goal. The objective, in fact, was simply to test the safety of the treatment. The misunderstanding a cure, and then no cure -- plunged the 23-year-old from hope to despair. And yet she couldn't let the idea of this experimental approach go.

Just days after learning that she would never walk again, that she would never know when her bladder was full, that she would not feel it if she broke her ankle, she was thinking about the next girl who might lie in this bed with a spinal injury. If Katie walked away from this experimental approachwhat would happen to others that came after her?

Her medical team provided a crash course in stem cell therapy to help Katie think things through. In this case the team had taken stem cells obtained from a five-day old embryo and converted them into cells that support communication between the brain and body. Those cells would be transplanted into the injured spines. Earlier experiments in animal models suggested that, once in place, these cells might help regenerate a patient's own nerve tissue. But before scientists could do the experiment, they needed to make sure the technique they were using was safe by using a small number of cells, too few to likely have any benefit. And that's why they wanted Katies help in this CIRM-funded trial. They explained the risks. They explained that she was unlikely to derive any benefit. They explained that she was just a step along the way. Even so, Katie agreed. She became the fifth patient in what's called a Phase I trial: part of the long, arduous process required to bring new therapies to patients. Shortly after she was treated the trial stopped enrolling patients for financial reasons.

That was in 2011. Since then, she has been through an intensive physical therapy program to increase her strength. She went back to college. She tried skiing and surfing. She learned how to make life work in this new body. But as she rebuilt her life she wondered if taking part in the clinical trial had truly made a difference.

"I was frustrated at first. I felt hopeless. Why did I even do this? Why did I even bother?" But soon she began to see how small advances were moving the science forward. She learned the steep challenges that await new therapies. Then in 2014, she discovered that the research she participated in was deemed to be safe and is about to enter its next phase, thanks to a $14.3 million grant from CIRM to Asterias Biotherapeutics. "This has been my wish from day one," Katie says.

"It gives me so much hope to know there is an organization that cares and wants to push these therapies forward, that wants to find a cure or a treatment," she says. "I don't know what I would do if I thought nobody cared, nobody wanted to take any risks, nobody wanted to put any funding into spinal cord injuries.

"I really have to have some ray of hope to hold onto, and for me, CIRM is that ray of hope."

Engineered Stem Cells repaired spinal cords in 5 out of 12 …

Engineered human stem cells have been used to enable paraplegic rats to walk independently and regain sensory perception. The implanted rats had some healing in their spinal cords.

Led by Dr. Shulamit Levenberg, of the Technion-Israel Institute of Technology, the researchers implanted human stem cells into rats with a complete spinal cord transection. The stem cells, which were derived from the membrane lining of the mouth, were induced to differentiate into support cells that secrete factors for neural growth and survival.

The work involved more than simply inserting stem cells at various intervals along the spinal cord. The research team also built a three-dimensional scaffold that provided an environment in which the stem cells could attach, grow and differentiate into support cells. This engineered tissue was also seeded with human thrombin and fibrinogen, which served to stabilize and support neurons in the rats spinal cord.

5 of 12 rats (42%) treated with the induced constructs demonstrated BBB scores exceeding 17, a compiled reflection of improved coordinated gait, plantar placement, weight support, recovery of toe clearance, trunk stability, and predominant parallel paw and tail position, suggesting regained cortical motor control.

The induced constructs promoted remarkable recovery in 42% of the rats, and show no efficacy in the remainder of the rats within the same group. This binary effect compels further investigation, since understanding of the underlying mechanisms causing substantial improvement in some animals and no practical improvement in others can render this method into an effective treatment.

Spinal cord injury (SCI), involving damaged axons and glial scar tissue, often culminates in irreversible impairments. Achieving substantial recovery following complete spinal cord transection remains an unmet challenge. Here, we report of implantation of an engineered 3D construct embedded with human oral mucosa stem cells (hOMSC) induced to secrete neuroprotective, immunomodulatory, and axonal elongation-associated factors, in a complete spinal cord transection rat model. Rats implanted with induced tissue engineering constructs regained fine motor control, coordination and walking pattern in sharp contrast to the untreated group that remained paralyzed (42 vs. 0%). Immunofluorescence, CLARITY, MRI, and electrophysiological assessments demonstrated a reconnection bridging the injured area, as well as presence of increased number of myelinated axons, neural precursors, and reduced glial scar tissue in recovered animals treated with the induced cell-embedded constructs. Finally, this construct is made of bio-compatible, clinically approved materials and utilizes a safe and easily extractable cell population. The results warrant further research with regards to the effectiveness of this treatment in addressing spinal cord injury.

Spinal cord injury – Symptoms and causes – Mayo Clinic

By LizaAVILA

Overview

A spinal cord injury damage to any part of the spinal cord or nerves at the end of the spinal canal (cauda equina) often causes permanent changes in strength, sensation and other body functions below the site of the injury.

If you've recently experienced a spinal cord injury, it might seem like every aspect of your life has been affected. You might feel the effects of your injury mentally, emotionally and socially.

Many scientists are optimistic that advances in research will someday make the repair of spinal cord injuries possible. Research studies are ongoing around the world. In the meantime, treatments and rehabilitation allow many people with spinal cord injuries to lead productive, independent lives.

Your ability to control your limbs after a spinal cord injury depends on two factors: the place of the injury along your spinal cord and the severity of injury to the spinal cord.

The lowest normal part of your spinal cord is referred to as the neurological level of your injury. The severity of the injury is often called "the completeness" and is classified as either of the following:

Additionally, paralysis from a spinal cord injury may be referred to as:

Your health care team will perform a series of tests to determine the neurological level and completeness of your injury.

Spinal cord injuries of any kind may result in one or more of the following signs and symptoms:

Emergency signs and symptoms of a spinal cord injury after an accident may include:

Anyone who experiences significant trauma to his or her head or neck needs immediate medical evaluation for the possibility of a spinal injury. In fact, it's safest to assume that trauma victims have a spinal injury until proved otherwise because:

Spinal cord injuries may result from damage to the vertebrae, ligaments or disks of the spinal column or to the spinal cord itself.

A traumatic spinal cord injury may stem from a sudden, traumatic blow to your spine that fractures, dislocates, crushes or compresses one or more of your vertebrae. It also may result from a gunshot or knife wound that penetrates and cuts your spinal cord.

Additional damage usually occurs over days or weeks because of bleeding, swelling, inflammation and fluid accumulation in and around your spinal cord.

A nontraumatic spinal cord injury may be caused by arthritis, cancer, inflammation, infections or disk degeneration of the spine.

The central nervous system comprises the brain and spinal cord. The spinal cord, made of soft tissue and surrounded by bones (vertebrae), extends downward from the base of your brain and is made up of nerve cells and groups of nerves called tracts, which go to different parts of your body.

The lower end of your spinal cord stops a little above your waist in the region called the conus medullaris. Below this region is a group of nerve roots called the cauda equina.

Tracts in your spinal cord carry messages between the brain and the rest of the body. Motor tracts carry signals from the brain to control muscle movement. Sensory tracts carry signals from body parts to the brain relating to heat, cold, pressure, pain and the position of your limbs.

Whether the cause is traumatic or nontraumatic, the damage affects the nerve fibers passing through the injured area and may impair part or all of your corresponding muscles and nerves below the injury site.

A chest (thoracic) or lower back (lumbar) injury can affect your torso, legs, bowel and bladder control, and sexual function. A neck (cervical) injury affects the same areas in addition to affecting movements of your arms and, possibly, your ability to breathe.

The most common causes of spinal cord injuries in the United States are:

Although a spinal cord injury is usually the result of an accident and can happen to anyone, certain factors may predispose you to a higher risk of sustaining a spinal cord injury, including:

At first, changes in the way your body functions may be overwhelming. However, your rehabilitation team will help you develop the tools you need to address the changes caused by the spinal cord injury, in addition to recommending equipment and resources to promote quality of life and independence. Areas often affected include:

Bladder control. Your bladder will continue to store urine from your kidneys. However, your brain may not be able to control your bladder as well because the message carrier (the spinal cord) has been injured.

The changes in bladder control increase your risk of urinary tract infections. The changes also may cause kidney infections and kidney or bladder stones. During rehabilitation, you'll learn new techniques to help empty your bladder.

Skin sensation. Below the neurological level of your injury, you may have lost part of or all skin sensations. Therefore, your skin can't send a message to your brain when it's injured by certain things such as prolonged pressure, heat or cold.

This can make you more susceptible to pressure sores, but changing positions frequently with help, if needed can help prevent these sores. You'll learn proper skin care during rehabilitation, which can help you avoid these problems.

Circulatory control. A spinal cord injury may cause circulatory problems ranging from low blood pressure when you rise (orthostatic hypotension) to swelling of your extremities. These circulation changes may also increase your risk of developing blood clots, such as deep vein thrombosis or a pulmonary embolus.

Another problem with circulatory control is a potentially life-threatening rise in blood pressure (autonomic hyperreflexia). Your rehabilitation team will teach you how to address these problems if they affect you.

Respiratory system. Your injury may make it more difficult to breathe and cough if your abdominal and chest muscles are affected. These include the diaphragm and the muscles in your chest wall and abdomen.

Your neurological level of injury will determine what kind of breathing problems you may have. If you have a cervical and thoracic spinal cord injury, you may have an increased risk of pneumonia or other lung problems. Medications and therapy can help prevent and treat these problems.

Fitness and wellness. Weight loss and muscle atrophy are common soon after a spinal cord injury. Limited mobility may lead to a more sedentary lifestyle, placing you at risk of obesity, cardiovascular disease and diabetes.

A dietitian can help you eat a nutritious diet to sustain an adequate weight. Physical and occupational therapists can help you develop a fitness and exercise program.

Following this advice may reduce your risk of a spinal cord injury:

Drive safely. Car crashes are one of the most common causes of spinal cord injuries. Wear a seat belt every time you drive or ride in a car.

Make sure that your children wear a seat belt or use an age- and weight-appropriate child safety seat. To protect them from air bag injuries, children under age 12 should always ride in the back seat.

What are stem cells and how will they be used to treat the …

By Sykes24Tracey

Stem cell research is often controversial but it has also led to incredible medical progress in recent years.

Stem cell research is at defining moment. Although it can be controversial and does raise a lot of important ethical issues, this area of medical science has been characterised by a number of important advances, ever since the first embryonic stem cells were isolated from mice in the 1980s. In the near future, it could reshape the way we treat some of the worlds most debilitating diseases.

Stem cells have already been used as treatment for a number of years think bone marrow transplant and they have the potential to help with many other medical conditions. They could also prove crucial for scientists wishing to understand more about human biology and development.

Studies using stem cells have benefited from important media coverage in recent years and many of them hailed as breakthroughs. However, the reality is often more complex, and a number of scientific and ethical challenges often stand in the way of successes in animal models being replicated in humans.

IBTimes UK takes a look at what stem cell research is, what it is used for and what the future looks like.

Stem cells could be defined as building block cells that have not yet differentiated into one cell type and could develop into many different cell types. Stem cells can continue to divide almost indenitely.

There are two main types of stem cells: embryonic stem cells and adult stem cells.

Embryonic stem cells were first isolated in mice in the early 1980s at the University of Cambridge. All developing embryos contains a number of stem cells that can go on to develop into different cell types. In humans, these cells can be isolated from around five days after the egg has been fertilised around 50 to 100 stem cells are present at that stage.

These cells are isolated from embryos that have been donated by couples who have been through IVF and have extra embryos left which were not used during the treatment.

Stem cells are also found in adults, particularly in the bone marrow, the blood, the eyes, the brain and the muscles. They are also known as somatic stem cells.

They can also differentiate into other cells, but into a much more limited number than embryonic stem cells. They range from cells that are able to form different kinds of tissues to more specialised cells that form just some of the cells of a particular tissue or organ. They also have the ability to divide and reproduce indefinitely.

Brivanlou, Rockefeller University, Brivanlou Laboratory New York, New York, USA: Human neural rosette primordial brain cells, differentiated from embryonic stem cells Confocal, 10x (Dr Gist F Croft, Lauren Pietilla, Stephanie Tse, Dr. Szilvia Galgoczi, Maria Fenner, Dr Ali H. Brivanlou)

Scientists have also found a way to make induced pluripotent stem cells cells taken from any adult tissue and genetically modified to behave like an embryonic stem cell (and thus able to differentiate into any cell type). The term pluripotant refers to the fact that the stem cells can produce almost all of the cells in the body.

To create these induced pluripotent stem cells, researchershave learnt to reprogramme the genes of human adult cells. A major 2007 US study, found that introducing 14 genes could reprogramme the cells to become stem cells, and the researchers then narrowed this down to four genes. Subsequent studies have built on this knowledge to find new, safer ways to turn adult cells into pluripotant stem cells.

Stem cells are already used to help a number of patients around the world. For nearly 50 years, they have been used in the form of bone marrow transplants.

Indeed, bone marrow contains stem cells that can produce many different blood cells. A bone marrow transplant can be used to treat people with blood cancers or genetic blood disorders, such as sickle cell anaemia. The stem cell turn into healthy blood cells that can help the patient. Some hospitals also use stem cells to grow skin grafts for patients with life-threatening burns. It is also possible to receive a stem cell therapy based on limbal stem cells (in the eye) to repair damaged corneas.

Stem cells are also very useful for scientists conducting basic research on diseases, as they can be used to model a large number of conditions. Recent studies have used stem cells to model the nerve cells that are lost in Alzheimers disease or to model deafness or Autism Spectrum disorder.

Scientists have gained a better understanding of blood stem cells (Alden Chadwick/Flickr)

A number of treatment using stem cells has been tested by researchers around the world. A type of patients that could be helped by stems cells are those suffering from spinal cord injuries. Stem cell therapy for spinal cord repair could be used to promote the growth of nerve cells directly or to transplant cells that protect the nerves and help them function.

One of most important studies in this area was published in October 2010. tested the used embryonic stem cells on patients in the US who had sustained a spinal cord injury in the previous 14 days. Preliminary findings were encouraging.

Studies have also been conducted to assess the safety and efficacy of stem cells in helping patients who suffered a stroke. The idea is that stem cells could help in rehabilitation after a persons brain has been damaged by the stroke. Stem cells have also been investigated to treat diseases such as MS, diabetes and to reverse ageing.

Beyond clinical trials, which still remain limited in number, many of the preliminary research opens up a number of very interesting perspectives. One of the main area of interest is growing organs in the lab from tissues created from stem cells. These organs may one day be used for transplantation in humans.

Recently, stem cells have been shown to present an interest to improve fertility treatments with the creation of a new technique in mice in-vitro gametogenesis. The idea is to create eggs and sperm using pluripotant stem cells.

Spinal Cord Injury Treatment with Stem Cells – Stem Cells …

By daniellenierenberg

Spinal cord injury is the injury to the spinal cord, a very serious form of trauma with enduring effects on the patients daily life. The spinal cord is approximately 18 inches long and extends from brain base at the neck and ending just above the buttocks. It has numerous nerves known as upper motor neurons (UMNs) and is responsible for transmitting signals back and forth from the brain to different parts on the body.Human beings are in a position to feel pain and move their limbs because messages are sent via the spinal cord, therefore if the spinal cord is damaged some or all of these impulses may not be sent.

Usually, a spinal cord injury happens as a result of an impulsive accident or event, we list here some of the most common causes of spinal cord injury:

An aggressive attack like being stabbed or shot Diving into very shallow water and hitting the bottom Trauma to the face, head, back or the neck region during a motor accident Falling from a very high height Electrical accident Injuries while engaging in sports Severe twist of the torso middle portion

1) Incomplete spinal cord injuries; the spinal cord is partially affected and in this case, the patient retains some functions depending on the degree of the injury. Some of the common types of partial spinal cord include anterior cord syndrome, central cord syndrome and brown-sequard syndrome.

2) Complete spinal cord injuries; this type occurs when the spinal cord is fully damaged and there is no function below the level of injury. However, with proper treatment and physical therapy, it is possible for a patient to regain some functions.

Challenges walking Loss of control of bladder or bowels Difficulties moving arms and legs Headaches Unconsciousness Pain, pressure, and stiffness in the neck/or back region Spreading numbness feelings Unnatural head positioning Signs of shock Loss of libido Loss of fertility Bedsores How are spinal cord injuries diagnosed?

Usually, physicians examine patients for spinal cord injuries based on factors like the location, type and the symptoms of the injury. However, no single test can assess 100% these injuries; instead, doctors depend on a number of protocols such as:

Clinical evaluation; the doctor will keenly observe your symptoms, carry out blood tests, ask detailed questions about your condition and follow your eye movement Imaging tests; the doctor may request a magnetic reasoning imaging or radiological imaging to view the spinal column, spinal cord, and brain

Stem cells are found in all multi-cellular organisms and are well known for their remarkable ability to differentiate into almost any other type of cell. Therefore depending on the disease, stem cells can be transplanted into the patient to assist renewal and regeneration of the previously dying cells.This principle is now being used for a spinal cord injury using stem cells; it assists patients with the recovery process and restores their physiological and sensory ability.Currently, no stem cell therapy has been approved as a complete cure for spinal injuries. Stem cell therapy is used to improve conditions and symptoms whilst allowing the patient to enjoy a better quality of life after injury.

Exogenous and endogenous repair.While in exogenous repair the stem cells are first grown in the lab and then injected into the patient, in endogenous repair stem cells are injected into the injured site and the results depend on the bodys ability to change stem cells into the needed cells.

Adult neural stem cells can differentiate into different cell types. Consequently, researchers are taking advantage of this regenerative ability and are trying to come up with ways to reintroduce the bodys own stem cells into the damaged spinal cord. Research in rats shows that transplanting oligodendrocyte (support cells that make myelin) and astrocyte (boost nerve function) precursors from the neural stem cells can protect axons and reduce motor neuron damage.

Embryonic stem cells are the best type of stem cells and researchers are developing ways to turn embryonic stem cells into oligodendrocyte which have successfully repaired neural functions in animal models. However, using the same approach in a clinical trial is very challenging; it is close to impossible to make oligodendrocyte without also making other unasked for cells.

Induced Pluripotent Stem cells (IPs) are just like embryonic stem cells and can be made from the skin or any other tissue cell. They are easily reachable and offer a great source of cells that match the patients profile, hence theres no chance of rejection.

By combining the Anti CD2 human clonal antibodies and Anti-cytokines monoclonal antibodies, we create injections. This helps to reduce the inflammation, axonal degeneration and to prevent demyelination. Lysis functions of leukocyte cells get enhanced as well.

Quadriplegia | Types of Paralysis | Brain and Spinal Cord …

By Dr. Matthew Watson

What Is Quadriplegia?

Paralysis can be either partial, periodic, complete, or incomplete. Paralysis of both the arms and legs has been traditionally been called quadriplegia. Quad comes from the Latin for four and plegia comes from the Greek for inability to move. Currently the term tetraplegia is becoming more popular, but it means the same thing. Tetra is from the Greek for inability to move.

The primary cause of quadriplegia is a spinal cord injury, but other conditions such as cerebral palsy and strokes can cause a similar appearing paralysis. The amount of impairment resulting from a spinal cord injury depends on the part of the spinal cord injured and the amount of damage done. Injury to the spinal cord can be devastating because the spinal cord and the brain are the main parts of the central nervous system, which sends messages throughout your body.

When the spinal cord is injured the brain cannot properly communicate with it and so sensation and movement are impaired. The spinal cord is not the spine itself; it is the nerve system encased in the vertebrae and discs which make up the spine.

Quadriplegia occurs when the neck area of the spinal cord is injured. The severity of the injury and the place it occurred at determine the amount of function a person will maintain. A major spinal cord injury may interfere with breathing as well as with moving the limbs. A patient with complete quadriplegia has no ability to move any part of the body below the neck; some people do not even have ability to move the neck.

Sometimes people with quadriplegia can move their arms, but have no control over their hand movements. They cannot grasp things or make other motions which would allow them a little independence. New treatment options have been able to help some of these patients regain hand function.

Quadriplegia causes many complications which will need careful management:

Immediate treatment of quadriplegia consists of treating the spinal cord injury or other condition causing the problem. In the case of a spinal cord injury, you will immobilized with special equipment to prevent further injury, while medical personnel work to stabilize your heart rate, blood pressure, and over all condition. You may be intubated to assist your breathing. This means that flexible tube carrying oxygen will be inserted down your throat. Imaging tests will be used to determine the extent of your injury.

Surgery may be needed to relieve pressure on the spine from bone fragments or foreign objects. Surgery may also be used to stabilize the spine, but no form of surgery can repair the damaged nerves of the spinal cord. Unfortunately, the nerve damage caused by the initial spinal cord injury has a tendency to spread. The reasons for this tendency are not completely understood by researchers, but it is related to spreading inflammation as blood circulation decreases and blood pressure drops.

The inflammation causes nerve cells not directly in the injured area to die. A powerful corticosteroid, methylprednisolone (Medrol) can sometimes help prevent the spread of this damage if it is given within eight hours of the original injury; however, methylprednisolone can cause serious side effects and not all doctors are convinced that it is beneficial.

Rehabilitation for quadriplegia once consisted primarily of training to learn how to deal with your new limitations. Passive physical therapy was given to help prevent the muscles from atrophying. Today, many new options are offering quadriplegia patients new hope. These new options combine older methods with new technology with encouraging results.

While passive physical therapy once consisted solely of the therapists manipulating the patients arms and legs in an effort to increase circulation and retain muscle tone, today therapists can use electrodes to stimulate the patients muscles and give them an optimal workout. This technology is called functional neuromuscular stimulation (FNS). FNS stimulates the intact peripheral nerves so that the paralyzed muscles will contract.

The contractions are stimulated using either electrodes that have been placed on the skin or that have been implanted. With FNS, the patient may ride a stationary bicycle to improve muscle and cardiac function and prevent the muscles from atrophying. An implantable FNS system has been used to help people with some types of spinal injury regain use of their hands.

This is an option for people with quadriplegia, who have some voluntary use of their arms. The shoulders position controls the stimulation to the hands nerves, allowing the individual to pick up objects at will. Tendon transfer is another option which allows some people with quadriplegia more use of the arms and hands. This complicated surgery transfers a nonessential muscle with nerve function to the shoulder or arm to help restore function. FNS may be used in conjunction with tendon transfer.

Other forms of treatments for quadriplegia are still in the experimental stage. Many clinical trials of new treatment options are run every year. If you or a loved one suffers from quadriplegia, you may want to consider one of these trials. Ask your doctor to help you find a suitable trial.

Stem Cell of America – Breakthrough Stem Cell Treatments …

By Dr. Matthew Watson

Treatment

The Stem Cell treatment performed at our clinics is a painless medical procedure where Stem Cells (cellular building blocks) are usually administered intravenously and subcutaneously (under the skin). The whole procedure takes approximately one hour and has no known negative side effects.

Following the treatment, the Fetal Stem Cells will travel throughout the body, detecting damaged cells and tissue and attempts to restore them. The Fetal Stem Cells can also stimulate existing normal cells and tissues to operate at a higher level of function, boosting the bodys own repair mechanisms to aid in the healing process. These highly adaptive cells then remain in the body, continually locating and repairing any damage they encounter.

As with any medical treatment, safety should be of the highest priority. The Stem Cells used in our treatment undergo extensive screening for possible infection and impurities.

Utilizing tests more sophisticated than those regularly used in the United States for Stem Cell research and transplant. Our testing process ensures we use only the healthiest cells to enable the safest and most effective Fetal Stem Cell treatment possible. And, unlike other types of Stem Cells, there is no danger of the bodys rejection of Fetal Stem Cells due to the fact they are immune privileged. This means that you can give the cells to any patient without matching, use of immunosuppressive drugs and without rejection. This unique quality eliminates the need for drugs used to suppress the immune system, which can leave a patient exposed to serious infections.

With over 4,000 patients treated, Stem Cell Of America has achieved positive results with a wide variety of illnesses, conditions and injuries. Often, in cases where the diseases continued to worsen, our patients have reported substantial improvements following the Stem Cell treatment.

Patients have experienced favorable developments such as reduction or elimination of pain, increased strength and mobility, improved cognitive function, higher tolerance for chemotherapy, and quicker healing and recovery.

To view follow up letters from patients, please visit the patient experiences page on our website.

All statements, opinions, and advice on this page is provided for educational information only. It is not a substitute for proper medical diagnosis and care. Like all medical treatments and procedures, results may significantly vary and positive results may not always be achieved. Please contact us so we may evaluate your specific case.

The $100 Million Plan to End Paralysis – Outside Magazine

By daniellenierenberg

I can see him in his glass-fronted Cambridge office from the foosball table in the light-filled central atrium. Hes standing there talking to a visitor and seems to be finishing up. This entire side of the third floor in MITs new Media Lab building is partitioned with glass, and professor Hugh Herr and his colleagues and whatever madness theyre up to in their offices and the open, gadget-filled, lower-floor lab are on display. Several people, myself included, are peering down, hoping to see a bit of magic.

Months ago, when I e-mailed Herr to propose writing an article about him, I told him about my rare bone cancer and resulting partial paralysis below the waist as a way to explain my interest in his work. Though I didnt tell him this, I also harbored a secret wish that he could help me. People write to Herr, a 52-year-old engineer and biophysicist, daily about his inspiring example. Theyve heard him promise an end to disability. They have conditions that medicine cant fix and futures they cant stand to consider. Theyre wishing for his intervention, wanting of hope. Crossing his threshold, Im the lucky one. Im here.

Download the Audm app for your iPhone to listen to more longform titles.

Herr welcomes me into his office, a clean, well-ordered space. Theres a round glass table with a laptop on it, a handful of hard office chairs, and a pair of prosthetic legs Herr designed that are arranged like statuary behind us, one in either corner. Above us on a wall looms a large mounted photograph of another pair of prosthetics. These are hand-carved from solid ash, with vines and flowers and six-inch heels. The real-life legs were famously worn by a friend of Herrs, the amputee track-and-field athlete and actress Aimee Mullins.

I have hobbled into Herrs office with a dented $20 stock metal cane on one side and a foot-lifting Blue Rocker brace on the other. (The dent is from my recently firing the cane at the wall.) I had imagined Herr noticing the cane and asking more about my story to see how he could fix me, like he has fixed so many others. The moment I realize that the meeting Id imagined isnt the meeting were going to haveIm here as a reporter, not a friend or patient, after allI start to stammer. Herr deftly resets the conversation by suggesting we look at his computer.

On it are the PowerPoint slides of his next big project, a breathtaking $100 million, five-year proposal focused on paralysis, depression, amputation, epilepsy, and Parkinsons disease. The work will be funneled through Herrs new brainchild, MITs Center for Extreme Bionics, a team of faculty and researchers assembled in 2014 that he codirects. After exploring various interventions for each condition, Herr and his colleagues will apply to the FDA to conduct human trials. One to-be-explored intervention in the brain might, with the right molecular knobs turned, augment empathy. If we increase human empathy by 30 percent, would we still have war? Herr asks. We may not.

As he continues with the presentation hes been giving to technologists, engineers, health researchers, and potential donorslast December alone, he keynoted in Dubai, Istanbul, and Las Vegaseach revolutionary intervention he mentions yields a boyish grin and a look that affirms: Yes, you heard that right. In a talk I hear him give a few weeks later, hell dare to characterize incurable paralysis as low-hanging fruit. In his outspoken willingness to fix everything, even things that some argue should be left alone, he knows how he sounds. If half the audience is frightened and the other half is intrigued, I know Ive done a good job, he says.

Herr on a 5.12 route on Arizonas Mount Lemmon in 1986. (Beth Wald/Aurora)

Herr calmly ticks off one condition after another. He shows me an animation of an innovative surgery that will restore an amputees lost proprioception, giving a person the ability to feel and control a prosthetic as if it were their own limb. In another slide, of a paralyzed man in a bulky walk-assisting exoskeleton suit, he asks me to imagine a futuristic treatment that uses light to control cells in muscle tissue. Then he presents a video clip of a rat with a severed spinal cord dragging around its paralyzed hind legs.

Having dragged my mostly unresponsive left leg around for two years, I think I know something about the rodents life. In the next clip, however, that rat, just 90 days later, is walking on all fours. A team at the MIT center led by Herrs colleague Robert Langer successfully regrew the rats spinal cord by implanting a dissolvable scaffold seeded with neural stem cells. In Herrs world, the limbless can be whole again, the paralyzed can walk. Making the extraordinary seem ordinary is maybe the whole point.

Herr himself is proof positive. Trim, fit, and handsome, he is the showpiece for the Center for Extreme Bionics. Im kind of what theyre selling, he says. The fuss over Herr has been building for decades but reached new levels in 2014, courtesy of his TED Talk, which has now been viewed in excess of 7.3 million times. In it, Herr describes the horrific 1982 winter climbing accident in New Hampshires White Mountains during which he suffered severe frostbite, leading to the amputation of both legs below the knee. Then 17, Herr was told hed never climb again. Instead, he rebuilt himself almost immediately, willfully reshaping his artificial legs and realizing that he wasnt handicapped, the technology was.

By hacking his prosthetic devices for his vertical world, he was able to quickly return to climbing, becoming the first athletedecades before Oscar Pistoriusto blur the line between para and not. His accomplishments landed him on the cover of Outside a year after his accident, something that sticks with him not because of the many accolades other climbers bestowed on him, or even the controversy it reignited around the tragic death of one of his rescuers, but because of the questions the article raised about how far Herr would be able to go. I was a sad case. I was going to end up in this machine shop, disabled, Herr recalls of the piece, pausing to let the perceived insult ripen in his mind. Yeah, its a real sad story.

The triumphant, fully realized man in the TED Talk is a marvel. His outrage at the unnecessary suffering from disability is fiercely personal. What first-time viewers like me invariably fixate on is the way Herr gracefully owns the stage. Hes wearing pants that end above the knee, revealing shimmering high-tech silver and black prosthetics. Herr is focused on what hes saying, not what his artificial legs are doing. The crime of physical impairment is that it often steals from a persons sense of self. If you didnt look below his knees, youd never guess that Herr is missing half of each leg. He walks through the world the way we all would hope to.

He has effectively ended his disability, or at least the perception of it, just as he said he would. Inspired by his accident, he earned a masters degree in mechanical engineering at MIT in 1993, followed by a Ph.D. at Harvard in biophysics. Ever since, Herr has produced a string of breakthrough products, starting with a computer-controlled artificial knee in 2003. In 2004, he created the biomechatronics group at MIT, a now 40-person R&D lab drawing on the fields of biology, mechanics, and electronics to restore function to those whove lost it. Three years later, the team produced a powered ankle-foot prosthesis that allows an amputee to walk with speed and effort comparable to those with biological legs. Called the emPower, the apparatus weighs a few pounds and houses 12 sensors, three computers, tensioning springs, and muscle-tendon actuators. The ankle system is manufactured by a private company Herr started called BionX.

Last year, Herr advanced another of his labs goals, to improve human performance beyond what nature intends by creating a brace-like exoskeleton device that reduces the metabolic cost of walking. The implications for people who want to get places fasteror perhaps a soldier trying to conserve energy on a long marchare vast.

In the near future, Herr and his colleagues at the MIT center are committed to, among other things, reversing paralysis. Herrs goal is to develop a synthetic spinal cord thataids the damaged original. A prosthesis, in other words.

In his office, Herr draws up his pant leg and rolls down a silicone sleeve to show me a newly developed fabric that lines the socket of his prosthetic and cushions the problematic intersection between the biological stump and the man-made limb. The exquisitely comfortable fitdigitally derived, he explains, but highly personalis something he delights over with a savoring gush.

With our first meeting nearing its end, I grow distracted thinking about the wounded few Herr has smiled upon. In 2014, he worked on a bionic prosthetic for the dancer Adrianne Haslet-Davis, who lost her left leg in the Boston Marathon bombing. Currently, hes working with Hari Budha Magar, a double-amputee former Gurkha soldier who plans to climb Mount Everest in 2018, and also Jim Ewing, an old New Hampshire climbing buddy. Ewing was climbing a wall on vacation in the Cayman Islands in 2014 when he fell with his teen daughter on belay. She couldnt brake the rope, and he plummeted some 60 feet, shattering his pelvis and left foot on impact.

The dancer, the Gurkha, the climber, and Herr himself are examples of what he often describes as the millions of humans who might appear broken but are not. Haslet-Davis, on a bionic limb embedded with dance intelligence, brilliantly performed the rumba again, and Ewing underwent a pioneering amputation procedure developed by Herrs biomechatronics team in partnership with MIT colleague and surgeon Matthew Carty, who performed the operation at Brigham and Womens Faulkner Hospital, to prepare Ewing for an advanced prosthesis. Magar will be outfitted with short prosthetics to reduce leg drag and sophisticated crutches for speed as he attempts Everest history.

The stories Herr tells, the future he sees, the beautifully functioning artificial limb before meits all I can do not to show him my atrophied left leg and ask for his godlike intervention to fix what I know is broken. But I dont, not yet.

When I wrote Herr to tell him about my interest in his work, I summarized my case history. I explained how in the summer of 2014, I found myself with increasingly debilitating nerve and lower-back pain. When I finally got an MRI, I learned that I had an extremely rare bone cancer called chordoma that had spread from my lower lumbar vertebrae into my right hip flexor. Radiation and a difficult multi-stage surgery successfully removed the softball-size tumor, but months later, possibly due to a loss of blood to the spinal cord, Id yet to regain sensation or strength in my hips and legs. The doctors didnt know if it was permanent, but the prognosis didnt look good.

Id expected a rapid, maybe even exceptional recovery. I am an athlete and adventurer who has had the good fortune to do a lot of cool stuff over the years. Id become a whitewater guide, climbed Grand Teton, raced the hill climb at Mount Washington on foot and by bike, and mountain-biked half the 3,000-mile-plus Great Divide route. I expected to complete the other half someday.

Id progressed from a walker to a cane, from a recumbent tricycle to a pedal-assist e-bike. Then my nerve regeneration halted. In May 2015, after the surgery, Id contacted Boston neurologist Bill David for muscle and nerve testing. An avid cyclist and kindredspirit, hed hopefully stuck needles into my skin every six months to chart my recovery. Late last year, he confirmed what I had already sensed. Short of a miracle, Id gone about as far as I could. I really wish that we had met on a mountain or river as opposed to a medical clinic, David said.

Id negotiated several stages of recovery, but the one I feared most was right nowat the end, my future fixed. Ive been coming to grips with who I am as an incomplete paraplegic and figuring out how to make the best version of this new person, I wroteto Herr.

Id imagined a stirring epilogue to our encounters, a moment perhaps when a radical trial arose and a crazy volunteer was needed. To be closer to the person I once was, I would try anythinginjected viruses, exoskeletal suits, implants. When I got together with a close friend for lunch, I told her how the story with Herr was progressing, and how the limbs he created were so advanced that Id read about people wanting them even though their leg complications didnt medically require amputation. She listened carefully. Let me ask you something, she said. Would you, um, get your legs cut off?

Exactly when in his childhood Hugh Herr decided to become the worlds best climber is impossible to pinpoint, but the goal was nurtured during family road trips across the West. He and his older brothers climbed, fished, and hiked in the American and Canadian Rockies, whetting the youthful Herrs appetite for adventure. The Shawangunk Mountains in New York were a four-and-a-half-hour drive from the Herrs home in Lancaster, Pennsylvania. The Gunks were an emerging mecca in the seventies, and Herr quickly established himself as a prodigy, climbing this stuff when I was 11 that only adults had done, and at 15 that no one else had done, he says.

When he and Jeff Batzer, a friend from Lancaster, drove to New Hampshires Mount Washington in January 1982 for a weekend ice-climbing outing, it wasnt to do anything audacious. Theyd attempt a classic route in Huntingtons Ravine, and maybe, depending on the weather and avalanche conditions, summit Mount Washington before racing down for the 12-hour drive home. Herr was a 17-year-old junior in high school, his friend Batzer, 20.

The decision to tack on the summit of Washington turned out to be a tragic mistake. They left a sleeping bag and bivy sack behind to reduce weight but encountered howling winds and blizzard conditions near the top, and they ended up losing their way, mistakenly descending into a different valley from where theyd come.

After four days trekking through a storm in deep snow and below-freezing temperatures to find their way out, Herr was no longer able to walk. Early on in the odyssey, he had punched through a frozen streambed into shin-deep water, soaking his boots and pants, and was suffering from severe frostbite. In Second Ascent, a biography by Alison Osius, Herr said that he had reconciled himself to death when a backcountry snowshoer saw some of Batzers tracks and followed them to a makeshift shelter the two were bivouacked in. The climbers were evacuated to a nearby hospital in Littleton, where doctors treated both for hypothermia and frostbite. Herrs legs were in terrible shape. At the hospital, he learned that doctors might not be able to save them and that a member of his search party, a 28-year-old climbing-school instructor named Albert Dow, had been killed in an avalanche. Two months later, doctors amputated Herrs legs four inches below the knee. Batzers fingers on his right hand were amputated, along with his left foot and the toes on his right foot.

I asked my doctor after the amputation what Id be able to do with my new body, Herr recalls. The doctor said, What do you want to do? I said I wanted to drive a car, ride my bike, and climb. The doctor said youll be able to drive a car, but with hand controls. He said I would not be able to ride a bike or return to climbing.

Herr did all of the above within a year. He worked closely with his prosthetist on one pair of artificial legs after another and tinkered on his own in the machine shop of a vocational school hed begun attending in 1981. He soon figured out that he could hack his artificial limbs to suit the requirements of particular climbing routes. He built limbs that extended or shortened his stature; he carved out feet with wedge ends to slice into crevices. He began to knock off routes that he hadnt been able to do previously, including leading an ascent of Vandals at Skytop, the first 5.13 on the East Coast. It ignited a new controversy: that his adaptations were a form of cheating. Herr likes to tell audiences that he invited his affronted rivals to chop off their own legs.

Some people were bitter and angry about the accident, says Jim Ewing, a summer roommate of Herrs in the 1980s, and with Hugh coming back and climbing so well, they started making up excuses, saying things like, He can stand on a dime, his feet dont get sore, he doesnt have calf fatigue. Id just look at these people and think, By God, you havent seen this guy crawl to the toilet in the middle of the night because he doesnt have his legs on. He is handicapped; it is a handicap. People had no idea.

While there was a lot of media attention about Herrs accident, he kept private the struggles and self-doubt he faced after he lost his legs. When he returned to New Hampshire to climb again 18 months later, the unease from locals over Dows death and Herrs resurgence was palpable.

The harsh early views of Herr didnt soon go away. When I asked him what he thought when the American Alpine Club last year honored him at a celebratory awards evening in Denver, he said he was stunned. They had named him a new inductee of the Hall of Mountaineering Excellence for lasting contributions on and off the mountain. It shocked me, he said. The initial story line of the accident was that these young, irresponsible, incompetent climbers caused the death of an experienced, beloved local climber. That narrative went on for a very long time. So for two decades at least, I wouldnt even expect the American Alpine Club to invite me to be in the audience.

When Herr talks about Albert Dow, who he never met, its with the fondness of a friend. That was Albert! he recounts about Dows insistence that he go looking for Herr and Batzer because hed want someone to do the same for him. Last year, Herr told a Reddit audience that he strives to honor Dow. I hate the idea that his death somehow enabled me to live so I could do good work, he says. What I like is that his kindness and who he wasand his sacrificeinspired me to work really hard.

In 1985, Herr free-climbed New Hampshires exceptionally steep and unprotected Stage Fright, with his friend Jim Surette on belay. It was a significant and life-threatening milestone, and afterward Herr had a dream that set his new path. He describes a nightmare in which Surette, bunking on a neighboring couch, throws off his covers to reveal mangled, bloody, amputated legs. We both go Aaah! in the dream, says Herr, but then I turn to Jimmy and say, Dont worry, Jimmy, its just a dream. Im the one without legs. Prior to that, in all my dreams I would be running and jumping, and I would have my biological legs. It was the first time my brain recognized my new state.

Some mightve interpreted the nightmare with melancholy, an attempt to come to terms with a sorrowful lifelong condition. Herr saw it as a beautiful vision.

The auditorium is full at the Princeton, New Jersey, headquarters of the Robert Wood Johnson Foundation, all 150 in attendance looking stage left as Herr introduces an image of himself in a New Hampshire hospital room decades earlier. What do you see? he asks.

It is Herr in the moments after his legs have been amputated. The 17-year-old is gazing down at a white sheet and the outline of his stumps. The audience is riveted.

What do you see? he asks again. I see a new beginning, he declares. I see beauty.

Herr, who prefers to use the term unusual instead of handicapped or disabled, often says that he wouldnt want his biological legs back. He loves the legs he started building after the accident and has steadily improved upon for the past several decades.

His meteoric rise in academia is almost as improbable as his comeback to elite climbing. I actually graduated from high school not being able to take 10 percent of 100, he says. I had no idea what a percent was. His older brothers were all in construction. He understood that the family trade was unavailable to him, so he shut himself away and applied the same obsessive focus to science that hed once reserved for climbing. He read everything he could find and enrolled at the local college, Millersville University.

Wed watch all these films of animals locomoting to try to learn about motion, says Don Eidam, his first adviser at Millersville and an unapologetic superfan who writes a newsletter about Herr. Hed put all these ideas on my blackboard, and the chalk would literally be disintegrating. Hed call me at midnight with an idea. Ive never met anyone so committed or intense.

In 1991, Herr became the first student from Millersville to be accepted at MIT. The academic degrees, innovations, and honors have since overflowed. He is the holder or coholder of over 100 patents. The powered prosthesis he developed for ankle-foot amputees was the product of a special mind with a special motivation. By copying the behavior of a biologically intact leg, Herr and his biomechatronics lab were able to create a breakthrough replacement. In 2011, Time crowned him the leader of the bionic age. Last year he won Europes top prize for inventors, the prestigious Princess of Asturias Award.

In Hughs mind, he has not successfully innovated until people are able to benefit from his innovation, says Tyler Clites, a Harvard-MIT student who has worked in Herrs lab for six years. He has said to me, Look, Tyler, Ive invented hundreds of times, but Ive only ever innovated twice. The two items, his prosthetic knee and the ankle-foot, are the only ones commercially available to others.

The idea of an endlessly upgradable human is something Herr feels in his bones. I believe in the near future, in a decade or two, when you walk down the streets of Boston, youll routinely see people wearing bionic systems, Herr told ABC News in a 2016 interview. In 100 years, he thinks the human form will be unrecognizable. The inference is that the abnormal will be normal, beauty rethought and reborn. Unusual people like Herr will have come home.

At a small luncheon after his talk in New Jersey, the organizers ask me to say a few words about my condition. I give a five-minute recap of my struggles with cancer, the spinal-cord complication, and my up-and-down recovery. It is my first time speaking publicly about my situation. As I do, I sneak a glance or two at Herr. I wonder what he thinks hearing me tell my story. He is sitting immediately to my right, raking through a towering salad.

There is no clear signal from him, but I leave feeling that Ive pulled ever so slightly into his orbit. I am also beginning to understand the weight he bears of being a savior. A friend who saw his impassioned SXSW talk in 2015 told me how she raced up to thank him afterward, only to encounter a different guy. He was polite but aloof. She was put off, but I think I understand. The man has to set boundaries. He cant save everybody.

You might say that Herrs the sort of disrupter the research world needs, or you might say hes overpromising. One spinal-cord-injury scientist I spoke with wasnt so sure that a bold tech solution is the answer in a field long focused on the biology of nerve regeneration.

Nicholas Negroponte, the cofounder and former director of the MIT Media Lab, says Herrs sense of humor helps him handle any negative commentary. Its particularlyimportant when you do and say risky things, some of which invite harsh criticism, he says. You smile and keep going, because you know youre right.

A week after his talk in New Jersey, Herr and I meet up at a seafood restaurant near his MIT office. I arrive 30 minutes early, wanting to get situated. Having lived with my disability for some time now, I understand that I cant just sweep in like I used to. Herr, to my surprise, given his packed schedule, arrives ten minutes early.

Herr told me earlier that he rarely pushes himself on climbs anymore. He proudly mentioned his two preteen, homeschooled daughters, who are avid hikers and spend almost every weekend with Herrs former wife, Patricia Ellis Herr, in the White Mountains happily exhausting themselves. They long ago summited Mount Washington and have high-pointed in 46 of the 50 states.

Herr and I talk at length about some of the people he has worked with and why. The Haslet-Davis project took a group from his biomechatronics lab 200 days to create the prosthetic, counting down to the 2014 TED Talk. She said she wanted to dance again. I really related, he says. He told himself, Im an MIT professor, I have resources. The timeline was tight enough that there was a TED Talk plan A (with her) and plan B (without). As everyone knows who has watched the video, Herrs team hit its deadline. Haslet-Davis unforgettably danced again, and there wasnt a dry eye because of it.

But as incredible as the moment was, its a source of frustration that the prosthetic cant be permanently handed over to Haslet-Davis. While Herr would love to give it to her, its a prototype that would cost millions to reproduce. As for Herrs climbing buddy Jim Ewing, thats a similarly uncertain situation. Months after Ewing had his foot amputated, he was fitted with a newly designed ankle-foot prosthetic that responds to his brain waves and allows him to feel his appendage. It is also a prototype that Ewing will eventually have to return.

Haslet-Davis and Ewing understood that they were part of a research project and wouldnt be able to keep the prototypes. Meanwhile, Herrs knee and ankle prosthetics, which cost tens of thousands of dollars, arent yet widely covered by insurance and remain too expensive for most who have a need for them. Herr has been in discussions with insurers to try and change that. According to Amputee Coalition of America estimates, there are 185,000 new lowerextremity amputations annually in the U.S. By contrast, there are only 1,700 emPower ankles in circulation right now. About half of them are worn by vets, paid for through reimbursements covered by the Department of Veterans Affairs.

Herrs work is important and coming from a good place, says Alisha Sarang-Sieminski, an associate professor of bioengineering at the Massachusetts-based Franklin W. Olin College of Engineering, a school involved in numerous projects related to lower-cost accessibility design. But people have different needs for different contexts. Also, so much of the high tech is really not accessible to very many people financially. Should people keep building them? Definitely. Should we also explore basic solutions? Yes.

Still, Ewings pioneering amputation is a huge success for Herrs group, the Brigham and Womens surgical team, and, most notably, Ewing. When I visited him at a climbing gym near Portland, Maine, he was planning a trip back to the Cayman Islands. For Ewing, the amputation has reduced the acute pain he used to feel in his biological foot and dramatically changed his outlook. He says that after his accident, he contemplated suicide. Being alive isnt enough, he says. Breathing isnt enough. I had to do something. Hugh understood my motivation probably better than I did.

Herr hadnt seen Ewing for years when he got an e-mail from him asking for advice about his foot. He was in a bad place, says Herr. Also, I really felt for his daughter. I know guilt so well, that poor girl.

Ewing says that the way hed set up the ropes is to blame for his daughters inability to brake the fall. Though she has returned to climbing at the gym and bouldering, she wasnt interested in rope climbing in the accidents aftermath, and Ewing worried that hed ruined the sporta passion theyd shared for yearsfor her.

Meanwhile, the gift Herr has given Ewing is exceptional. It might be the first time Herr is not the most technologically advanced lower-limb amputee. Herr often describes himself and others facing disabilities as astronauts testing new life-enabling technologies. As for his own legs, Herr wants to go even further but would need to leave the U.S. to undergo the operation he has in mind. Id love to do it, he says, without revealing any details about the procedure. Im just weighing the risk. I definitely dont want to go backwards.

In the short term, hes using a newly designed set of titanium legs and pushing forward on his work, noting hoped-for funding this year from the military to show we can synthetically take over a paralyzed limb. Herr then asks about my rehabilitation experience. This is finally my chance, I think, to ask if theres anything he can do for me.

I tell him that I identify with amputees and often wonder how some people without legs are more adept than some of us with them. Every time I watch a person with artificial legs walking, I selfishly wonder, Why not me? Why not us? Herr says they have some good ideas but acknowledges that the field has been way more successful in the amputation arena than with spinal-cord injuries. Its hard, he says.

While Herr has complete autonomy selecting projects in his lab, his interventions are rare, and they dont happen unless the time and circumstances are right. Often, people ask for help and I dont have the resources or the solution, he says. Exceptions like Haslet-Davis and Ewing come from feeling deeply about it and being in the position to make it happen.

I realize talking to Herr that its not my story thats weak, its the technology. Id incorrectly understood his comment about an imminent cure. Paralysis is lowhanging fruit in that its a condition they can impact in ten to twenty years instead of fifty. There are no toys to play with in Herrs lab closet. Not yet.

Before Herr and I wrap up our last visit, I ask what hed do if he were at an impasse. Its clear, at least to me, that Im talking about myself. Being a scientist, he focuses on process. He says he throws everything and anything at a problem. He visualizes each idea as a rock and starts turning them over. He mentions an acquaintance who came to see him earlier in the day who was struggling with depression. Herr started in, imagining at hyperspeed all the places the person might go and hadnt yet. Acupuncture? No? Meditation? No? Are you running? No? What medications have you tried? One? One! Theres like 20 antidepressants! Go, go, go! he says he wanted to plead. He chuckles at his overexuberance, but his belief is real. This can be solved!

When I say goodbye to Herr and watch him bound down from the upper level of the restaurant to the rain-drenched sidewalk, Im struck by a malaise. Maybe its the rain. Maybe its the opportunity lost. Maybe its the way he flipped a switch on his emPower ankle and raced effortlessly into the street. But then I think about Herr turning over one rock at a time and the span of possibilities he presented to help with depression. Im not out of options. There are hundreds of researchers working on a paralysis cure, and I immediately think of a world map I saw recently on a website with dozens of bright red circles representing centers of innovation. I can hear the words of my neurologist, who on my last visit leaned in with something else when he said goodbye. Keep moving, he urged. Theres even a clinic in New Hampshire I heard about where theyve produced exceptional walking recoveries using a robotic gait trainer available nowhere else in the U.S.

I begin to wonder, was Herrs story about his depressed acquaintance allegorical? An on-the-spot intervention? Had I just been, ever so lightly, smiled upon, too?

Repairing the Nervous System with Stem Cells | stemcells …

By daniellenierenberg

by David M. Panchision*

Diseases of the nervous system, including congenital disorders, cancers, and degenerative diseases, affect millions of people of all ages. Congenital disorders occur when the brain or spinal cord does not form correctly during development. Cancers of the nervous system result from the uncontrolled spread of aberrant cells. Degenerative diseases occur when the nervous system loses functioning of nerve cells. Most of the advances in stem cell research have been directed at treating degenerative diseases. While many treatments aim to limit the damage of these diseases, in some cases scientists believe that damage can be reversed by replacing lost cells with new ones derived from cells that can mature into nerve cells, called neural stem cells. Research that uses stem cells to treat nervous system disorders remains an area of great promise and challenge to demonstrate that cell-replacement therapy can restore lost function.

The nervous system is a complex organ made up of nerve cells (also called neurons) and glial cells, which surround and support neurons (see Figure 3.1). Neurons send signals that affect numerous functions including thought processes and movement. One type of glial cell, the oligodendrocyte, acts to speed up the signals of neurons that extend over long distances, such as in the spinal cord. The loss of any of these cell types may have catastrophic results on brain function.

Although reports dating back as early as the 1960s pointed towards the possibility that new nerve cells are formed in adult mammalian brains, this knowledge was not applied in the context of curing devastating brain diseases until the 1990s. While earlier medical research focused on limiting damage once it had occurred, in recent years researchers have been working hard to find out if the cells that can give rise to new neurons can be coaxed to restore brain function. New neurons in the adult brain arise from slowly-dividing cells that appear to be the remnants of stem cells that existed during fetal brain development. Since some of these adult cells still retain the ability to generate both neurons and glia, they are referred to as adult neural stem cells.

These findings are exciting because they suggest that the brain may contain a built-in mechanism to repair itself. Unfortunately, these new neurons are only generated in a few sites in the brain and turn into only a few specialized types of nerve cells. Although there are many different neuronal cell types in the brain, we now know that these new neurons can quot;plug inquot; correctly to assist brain function.1 The discovery of these cells has spurred further research into the characteristics of neural stem cells from the fetus and the adult, mostly using rodents and primates as model species. The hope is that these cells may be able to replenish those that are functionally lost in human degenerative diseases such as Parkinson's Disease, Huntington's Disease, and amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), as well as from brain and spinal cord injuries that result from stroke or trauma.

Scientists are applying these new stem cell discoveries in two ways in their experiments. First, they are using current knowledge of normal brain development to modulate stem cells that are harvested and grown in culture. Researchers can then transplant these cultured cells into the brain of an animal model and allow the brain's own signals to differentiate the stem cells into neurons or glia. Alternatively, the stem cells can be induced to differentiate into neurons and glia while in the culture dish, before being transplanted into the brain. Much progress has been made the last several years with human embryonic stem (ES) cells that can differentiate into all cell types in the body. While ES cells can be maintained in culture for relatively long periods of time without differentiating, they usually must be coaxed through many more steps of differentiation to produce the desired cell types. Recent studies, however, suggest that ES cells may differentiate into neurons in a more straightforward manner than may other cell types.

Figure 3.1. The NeuronWhen sufficient neurotransmitters cross synapses and bind receptors on the neuronal cell body and dendrites, the neuron sends an electrical signal down its axon to synaptic terminals, which in turn release neurotransmitters into the synapse that affects the following neuron. The brain neurons that die in Parkinson's Disease release the transmitter dopamine. Oligodendrocytes supply the axon with an insulating myelin sheath.

Second, scientists are identifying growth (trophic) factors that are normally produced and used by the developing and adult brain. They are using these factors to minimize damage to the brain and to activate the patient's own stem cells to repair damage that has occurred. Each of these strategies is being aggressively pursued to identify the most effective treatments for degenerative diseases. Most of these studies have been carried out initially with animal stem cells and recipients to determine their likelihood of success. Still, much more research is necessary to develop stem cell therapies that will be useful for treating brain and spinal cord disease in the same way that hematopoietic stem cell therapies are routinely used for immune system replacement (see Chapter 2).

The majority of stem cell studies of neurological disease have used rats and mice, since these models are convenient to use and are well-characterized biologically. If preliminary studies with rodent stem cells are successful, scientists will attempt to transplant human stem cells into rodents. Studies may then be carried out in primates (e.g., monkeys) to offer insight into how humans might respond to neurological treatment. Human studies are rarely undertaken until these other experiments have shown promising results. While human transplant studies have been carried out for decades in the case of Parkinson's disease, animal research continues to provide improved strategies to generate an abundant supply of transplantable cells.

The intensive research aiming at curing Parkinson's disease with stem cells is a good example for the various strategies, successful results, and remaining challenges of stem cell-based brain repair. Parkinson's disease is a progressive disorder of motor control that affects roughly 2% of persons 65 years and older. Triggered by the death of neurons in a brain region called the substantia nigra, Parkinson's disease begins with minor tremors that progress to limb and bodily rigidity and difficulty initiating movement. These neurons connect via long axons to another region called the striatum, composed of subregions called the caudate nucleus and the putamen. These neurons that reach from the substantia nigra to the striatum release the chemical transmitter dopamine onto their target neurons in the striatum. One of dopamine's major roles is to regulate the nerves that control body movement. As these cells die, less dopamine is produced, leading to the movement difficulties characteristic of Parkinson's disease. Currently, the causes of death of these neurons are not well understood.

For many years, doctors have treated Parkinson's disease patients with the drug levodopa (L-dopa), which the brain converts into dopamine. Although the drug works well initially, levodopa eventually loses its effectiveness, and side-effects increase. Ultimately, many doctors and patients find themselves fighting a losing battle. For this reason, a huge effort is underway to develop new treatments, including growth factors that help the remaining dopamine neurons survive and transplantation procedures to replace those that have died.

The strategy to use new cells to replace lost ones is not new. Surgeons first attempted to transplant dopamine-releasing cells from a patient's own adrenal glands in the 1980s.2,3 Although one of these studies reported a dramatic improvement in the patients' conditions, U.S. surgeons were only able to achieve modest and temporary improvement, insufficient to outweigh the risks of such a procedure. As a result, these human studies were not pursued further.

Another strategy was attempted in the 1970s, in which cells derived from fetal tissue from the mouse substantia nigra was transplanted into the adult rat eye and found to develop into mature dopamine neurons.4 In the 1980s, several groups showed that transplantation of this type of tissue could reverse Parkinson's-like symptoms in rats and monkeys when placed in the damaged areas.The success of the animal studies led to several human trials beginning in the mid-1980s.5,6 In some cases, patients showed a lessening of their symptoms. Also, researchers could measure an increase in dopamine neuron function in the striatum of these patients by using a brain-imaging method called positron emission tomography (PET) (see Figure 3.2).7

The NIH has funded two large and well-controlled clinical trials in the past 15 years in which researchers transplanted tissue from aborted fetuses into the striatum of patients with Parkinson's disease.7,8 These studies, performed in Colorado and New York, included controls where patients received quot;shamquot; surgery (no tissue was implanted), and neither the patients nor the scientists who evaluated their progress knew which patients received the implants. The patients' progress was followed for up to eight years. Unfortunately, both studies showed that the transplants offered little benefit to the patients as a group. While some patients showed improvement, others began to suffer from dyskinesias, jerky involuntary movements that are often side effects of long-term L-dopa treatment. This effect occurred in 15% of the patients in the Colorado study.7 and more than half of the patients in the New York study.8 Additionally, the New York study showed evidence that some patients' immune systems were attacking the grafts.

However, promising findings emerged from these studies as well. Younger and milder Parkinson's patients responded relatively well to the grafts, and PET scans of patients showed that some of the transplanted dopamine neurons survived and matured. Additionally, autopsies on three patients who died of unrelated causes, years after the surgeries, indicated the presence of dopamine neurons from the graft. These cells appeared to have matured in the same way as normal dopamine neurons, which suggested that they were acting normally in the brain.

Figure 3.2. Positron Emission Tomography (PET) images from a Parkinson's patient before and after fetal tissue transplantation. The image taken before surgery (left) shows uptake of a radioactive form of dopamine (red) only in the caudate nucleus, indicating that dopamine neurons have degenerated. Twelve months after surgery, an image from the same patient (right) reveals increased dopamine function, especially in the putamen. (Reprinted with permission from N Eng J Med 2001;344(10) p. 710.)

Researchers in Sweden followed the severity of dyskinesia in patients for eleven years after neural transplantation and found that the severity was typically mild or moderate. These results suggested that dyskinesias were due to effects that were distinct from the beneficial effects of the grafts.9 Dyskinesias may therefore be related to the ways that transplantation disturbs other cells in the brain and so may be minimized by future improvements in therapy. Another study that involved the grafting of cells both into the striatum (the target of dopamine neurons) and the substantia nigra (where dopamine neurons normally reside) of three patients showed no adverse effects and some modest improvement in patient movement.10 To determine the full extent of therapeutic benefits from such a procedure and confirm the reliability of these results, this study will need to be repeated with a larger patient population that includes the appropriate controls.

The limited success of these studies may reflect variations in the fetal tissue used for transplantation, which is of limited quantity and can not be standardized or well-characterized. The full complement of cells in these fetal tissue samples is not known at present. As a result, the tissue remains the greatest source of uncertainty in patient outcome following transplantation.

The major goal for Parkinson's investigators is to generate a source of cells that can be grown in large supply, maintained indefinitely in the laboratory, and differentiated efficiently into dopamine neurons that work when transplanted into the brain of a Parkinson's patient. Scientists have investigated the behavior of stem cells in culture and the mechanisms that govern dopamine neuron production during development in their attempts to identify optimal culture conditions that allow stem cells to turn into dopamine-producing neurons.

Preliminary studies have been carried out using immature stem cell-like precursors from the rodent ventral midbrain, the region that normally gives rise to these dopamine neurons. In one study these precursors were turned into functional dopamine neurons, which were then grafted into rats previously treated with 6-hydroxy-dopamine (6-OHDA) to kill the dopamine neurons in their substantia nigra and induce Parkinson's-like symptoms. Even though the percentage of surviving dopamine neurons was low following transplantation, it was sufficient to relieve the Parkinson's-like symptoms.11 Unfortunately, these fetal cells cannot be maintained in culture for very long before they lose the ability to differentiate into dopamine neurons.

Cells with features of neural stem cells have been derived from ES-cells, fetal brain tissue, brain tissue from neurosurgery, and brain tissue that was obtained after a person's death. There is controversy about whether other organ stem cell populations, such as hematopoietic stem cells, either contain or give rise to neural stem cells

Many researchers believe that the more primitive ES cells may be an excellent source of dopamine neurons because ES-cells can be grown indefinitely in a laboratory dish and can differentiate into any cell type, even after long periods in culture. Mouse ES cells injected directly into 6-OHDA-treated rat brains led to relief of Parkinson-like symptoms. Further investigation showed that these ES cells had differentiated into both dopamine and serotonin neurons.12 This latter type of neuron is generated in an adjacent region of the brain and may complicate the response to transplantation. Since ES cells can generate all cell types in the body, unwanted cell types such as muscle or bone could theoretically also be introduced into the brain. As a result, a great deal of effort is being currently put into finding the right quot;recipequot; for turning ES cells into dopamine neuronsand only this cell typeto treat Parkinson's disease. Researchers strive to learn more about normal brain development to help emulate the natural progression of ES cells toward dopamine neurons in the culture dish.

The recent availability of human ES cells has led to further studies to examine their potential for differentiation into dopamine neurons. Recently, dopamine neurons from human embryonic stem cells have been generated.13 One research group used a special type of companion cell, along with specific growth factors, to promote the differentiation of the ES cells through several stages into dopamine neurons. These neurons showed many of the characteristic properties of normal dopamine neurons.13 Furthermore, recent evidence of more direct neuronal differentiation methods from mouse ES cells fuels hope that scientists can refine and streamline the production of transplantable human dopamine neurons.

One method with great therapeutic potential is nuclear transfer. This method fuses the genetic material from one individual donor with a recipient egg cell that has had its nucleus removed. The early embryo that develops from this fusion is a genetic match for the donor. This process is sometimes called quot;therapeutic cloningquot; and is regarded by some to be ethically questionable. However, mouse ES cells have been differentiated successfully in this way into dopamine neurons that corrected Parkinsonian symptoms when transplanted into 6-OHDA-treated rats.14 Similar results have been obtained using parthenogenetic primate stem cells, which are cells that are genetic matches from a female donor with no contribution from a male donor.15 These approaches may offer the possibility of treating patients with genetically-matched cells, thereby eliminating the possibility of graft rejection.

Scientists are also studying the possibility that the brain may be able to repair itself with therapeutic support. This avenue of study is in its early stages but may involve administering drugs that stimulate the birth of new neurons from the brain's own stem cells. The concept is based on research showing that new nerve cells are born in the adult brains of humans. The phenomenon occurs in a brain region called the dentate gyrus of the hippocampus. While it is not yet clear how these new neurons contribute to normal brain function, their presence suggests that stem cells in the adult brain may have the potential to re-wire dysfunctional neuronal circuitry.

The adult brain's capacity for self-repair has been studied by investigating how the adult rat brain responds to transforming growth factor alpha (TGF), a protein important for early brain development that is expressed in limited quantities in adults.16 Injection of TGF into a healthy rat brain causes stem cells to divide for several days before ceasing division. In 6-OHDAtreated (Parkinsonian) rats, however, the cells proliferated and migrated to the damaged areas. Surprisingly, the TGF-treated rats showed few of the behavioral problems associated with untreated Parkinsonian rats.16 Additionally, in 2002 and 2003, two research groups isolated small numbers of dividing cells in the substantia nigra of adult rodents.17,18

These findings suggest that the brain can repair itself, as long as the repair process is triggered sufficiently. It is not clear, though, whether stem cells are responsible for this repair or if the TGF activates a different repair mechanism.

Many other diseases that affect the nervous system hold the potential for being treated with stem cells. Experimental therapies for chronic diseases of the nervous system, such as Alzheimer's disease, Lou Gehrig's disease, or Huntington's disease, and for acute injuries, such as spinal cord and brain trauma or stoke, are being currently developed and tested. These diverse disorders must be investigated within the contexts of their unique disease processes and treated accordingly with highly adapted cell-based approaches.

Although severe spinal cord injury is an area of intense research, the therapeutic targets are not as clear-cut as in Parkinson's disease. Spinal cord trauma destroys numerous cell types, including the neurons that carry messages between the brain and the rest of the body. In many spinal injuries, the cord is not actually severed, and at least some of the signal-carrying neuronal axons remain intact. However, the surviving axons no longer carry messages because oligodendrocytes, which make the axons' insulating myelin sheath, are lost. Researchers have recently made progress to replenish these lost myelin-producing cells. In one study, scientists cultured human ES cells through several steps to make mixed cultures that contained oligodendrocytes. When they injected these cells into the spinal cords of chemically-demyelinated rats, the treated rats regained limited use of their hind limbs compared with un-grafted rats.19 Researchers are not certain, however, whether the limited increase in function observed in rats is actually due to the remyelination or to an unidentified trophic effect of the treatment.

Getting neurons to grow new axons through the injury site to reconnect with their targets is even more challenging. While myelin promotes normal neuronal function, it also inhibits the growth of new axons following spinal injury. In a recent study to attempt post-trauma axonal growth, Harper and colleagues treated ES cells with a combination of factors that are known to promote motor neuron differentiation.20 The researchers then transplanted these cells into adult rats that had received spinal cord injuries. While many of these cells survived and differentiated into neurons, they did not send out axons unless the researchers also added drugs that interfered with the inhibitory effects of myelin. The growth effect was modest, and the researchers have not yet seen evidence of functional neuron connections. However, their results raise the possibility that signals can be turned on and off in the correct order to allow neurons to reconnect and function properly. Spinal injury researchers emphasize that additional basic and preclinical research must be completed before attempting human trials using stem cell therapies to repair the trauma-damaged nervous system.

Since myelin loss is at the heart of many other degenerative diseases, oligodendrocytes made from ES cells may be useful to treat these conditions as well. For example, scientists recently cultured human ES cells with a combination of growth factors to generate a highly enriched population of myelinating oligodendrocyte precursors.21,22 The researchers then tested these cells in a genetically-mutated mouse that does not produce myelin properly. When the growth factor-cultured ES cells were transplanted into affected mice, the cells migrated and differentiated into mature oligodendrocytes that made myelin sheaths around neighboring axons. These researchers subsequently showed that these cells matured and improved movement when grafted in rats with spinal cord injury.23 Improved movement only occurred when grafting was completed soon after injury, suggesting that some post-injury responses may interfere with the grafted cells. However, these results are sufficiently encouraging to plan clinical trials to test whether replacement of myelinating glia can treat spinal cord injury.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is characterized by a progressive destruction of motor neurons in the spinal cord. Patients with ALS develop increasing muscle weakness over time, which ultimately leads to paralysis and death. The cause of ALS is largely unknown, and there are no effective treatments. Researchers recently have used different sources of stem cells to test in rat models of ALS to test for possible nerve cell-restoring properties. In one study, researchers injected cell clusters made from embryonic germ (EG) cells into the spinal cord fluid of the partially-paralyzed rats.24 Three months after the injections, many of the treated rats were able to move their hind limbs and walk with difficulty, while the rats that did not receive cell injections remained paralyzed. Moreover, the transplanted cells had migrated throughout the spinal fluid and developed into cells that displayed molecular characteristics of mature motor neurons. However, too few cells matured in this way to account for the recovery, and there was no evidence that the transplanted cells formed functional connections with muscles. The researchers suggest that the transplanted cells may be promoting recovery in some other way, such as by producing trophic factors.

This possibility was addressed in a second study in which scientists grew human fetal CNS stem cells in culture and genetically modified them to produce a trophic factor that promotes the survival of cells that are lost in ALS. When grafted into the spinal cords of the ALS-like rats, these cells secreted the desired growth factor and promoted the survival of the neurons that are normally lost in the ALS-like rats.25 While promising, these results highlight the need for additional basic research into functional recovery in ALS disease models.

Stroke affects about 750,000 patients per year in the

U.S. and is the most common cause of disability in adults. A stroke occurs when blood flow to the brain is disrupted. As a consequence, cells in affected brain regions die from insufficient amounts of oxygen. The treatment of stroke with anti-clotting drugs has dramatically improved the odds of patient recovery. However, in many patients the damage cannot be prevented, and the patient may permanently lose the functions of affected areas of the brain. For these patients, researchers are now considering stem cells as a way to repair the damaged brain regions. This problem is made more challenging because the damage in stroke may be widespread and may affect many cell types and connections.

However, researchers from Sweden recently observed that strokes in rats cause the brain's own stem cells to divide and give rise to new neurons.26 However, these neurons, which survived only a couple of weeks, are few in number compared to the extent of damage caused. A group from the University of Tokyo added a growth factor, bFGF, into the brains of rats after stroke and showed that the hippocampus was able to generate large numbers of new neurons.27 The researchers found evidence that these new neurons were actually making connections with other neurons. These and other results suggest that future stroke treatments may be able to coax the brain's own stem cells to make replacement neurons.

Taking an alternative approach, another group attempted transplantation as a means to treat the loss of brain mass after a severe stroke. By adding stem cells onto a polymer scaffold that they implanted into the stroke-damaged brains of mice, the researchers demonstrated that the seeded stem cells differentiated into neurons and that the polymer scaffold reduced scarring.28 Two groups transplanted human fetal stem cells in independent studies into the brains of stroke-affected rodents; these stem cells not only survived but migrated to the damaged areas of the brain.29,30 These studies increase our knowledge of how stem cells are attracted to diseased areas of the brain.

There is also increasing evidence from numerous animal disease models that stem cells are actively drawn to brain damage. Once they reach these damaged areas, they have been shown to exert beneficial effects such as reducing brain inflammation or supporting nerve cells. It is hoped that, once these mechanisms are better understood, this stem cell recruitment can potentially be exploited to mobilize a patient's own stem cells.

Similar lines of research are being considered with other disorders such as Huntington's Disease and certain congenital defects. While much attention has been called to the treatment of Alzheimer's Disease, it is still not clear if stem cells hold the key to its treatment. But despite the fact that much basic work remains and many fundamental questions are yet to be answered, researchers are hopeful that repair for once-incurable nervous system disorders may be amenable to stem cell based therapies.

Considerable progress has been made the last few years in our understanding of stem cell biology and devising sources of cells for transplantation. New methods are also being developed for cell delivery and targeting to affected areas of the body. These advances have fueled optimism that new treatments will come for millions of persons who suffer from neurological disorders. But it is the current task of scientists to bring these methods from the laboratory bench to the clinic in a scientifically sound and ethically acceptable fashion.

Americord Offers New Option for Banking Placental Tissue – Business Wire (press release)

By LizaAVILA

NEW YORK--(BUSINESS WIRE)--Americord, the fastest growing cord blood bank in the country, and a leader in the advancement of umbilical cord blood, cord tissue, and placental tissue banking, has expanded customer options to now offer placental tissue banking as a stand-alone service.

As one of the only companies to offer placental tissue banking, Americord believes in the importance of offering new mothers an opportunity to preserve their stem cells for potential future use. We are therefore launching placental tissue banking as a stand-alone service, without the need to bank umbilical cord blood.

While many families have embraced Americords cord blood and tissue bundles, some have expressed interest in storing only placental tissue, commented Erin Willigan, Vice-President of Marketing at Americord. We wanted to respond to their desire to select individual services that best fit their budget and future plans.

Placental tissue contains mesenchymal stem cells (MSCs) that are a genetic match to the mother. These stem cells are multipotent, meaning that they can differentiate into many different types of cells, including organ and muscle tissue, skin, bone, cartilage, and fat cells. The placenta uses these stem cells to grow and function during pregnancy. After baby is delivered, stem cells from the placenta can be collected and stored for potential future use.

Due to their ability to multiply and become many different types of tissue, MSCs hold great promise for regenerative treatments. Over 50 clinical trials are currently researching therapeutic uses for MSCs, including treatments for Type 1 Diabetes, Alzheimers, and spinal cord injuries.

Using donor stem cells to treat spinal cord injury

A new study in mice published in The Journal of Neuroscience details a potential therapeutic strategy that uses stem cells to promote recovery of motor activity after spinal cord injury.

The transplantation of neural stem cells could help promote repair of an injured spinal cord, but the interaction between donor cells and the resident cells that are part of the body's immune response to injury is not well understood.

Hal Nguyen, Aileen Anderson and colleagues found that mice receiving stem cells derived from donated human brain tissue required depletion of a specific population of immune cells in order to improve the mice's ability to walk along a glass plate. Although the donor cells survived equally when transplanted immediately or 30 days after injury, their location and cell type changed with time. These results suggest that immune cells populating the spinal cord at different time points after injury affect the ability of stem cells to promote functional recovery.

Ryan Custer, Elder grad injured at Oxford party, thanks community for their support – WCPO

By Dr. Matthew Watson

CINCINNATI -- Ryan Custer tearfully thanked the community for their support at his prayer service Sunday.

I cant thank you guys enough, he said in front of a standing ovation at Elder High Schools Fieldhouse.

Custer, an Elder grad and Wright State freshman, suffered a traumatic spinal injury at a large party in April after he tried to jump into a shallow, makeshift pool.

Family and friends welcomed Custer home on Wednesday. He had been been recovering and undergoing therapy at University of Cincinnati Medical Center. He also traveled to Chicago to be considered for a stem cell study at Rush University.

Doctors injected 20 million stem cells into Custers neck, and HBO has been following his progress.

Ryans brother, Nick Custer, thanked the West Side community for being so uplifting to his family.

It means the world to us. It just shows you what a special kid Ryan is as a 19-year-old kid going through this, its just overwhelming support, he said.

Nick said Ryan will continue rehabilitation in Cincinnati, and he said Ryan is looking forward to the start of Wright States season.

Ryan wants to get back to the team as soon as possible, and they all want him to come back and help however he can. He misses them, definitely, Nick said.
