RSCIs one-day treatment program in Florida, USA, is priced to bring stem cell treatment benefits to the greatest possible number of SCI patients.

Dallas, TX (PRWEB) March 26, 2014

The Repair Stem Cells Institute (RSCI http://www.repairstemcells.org) announces its new Double Benefits for SCI stem cell treatment program specifically to benefit sufferers of Spinal Cord Injuries (SCI). The Regenerative Center, headed by Dr. Melvin M. Propis, a well-known practitioner of stem cells science, is located in Ft. Lauderdale, Florida, U.S.A. RSCIs program is by far the least expensive SCI treatment program available using real stem cells treatments within FDA regulations.

A Spinal Cord Injury (SCI) refers to any injury to the spinal cord caused by trauma rather than disease. Depending on where the spinal cord and nerve roots are damaged, the symptoms can vary widely, from pain to paralysis to incontinence. SCIs are described as "incomplete," which normally means a partial but significant paralysis, to a "complete" injury, which means a total loss of function. The number of people in the United States in 2014 who have SCI has been estimated at over a quarter million, with approximately 12,000 new cases each year.

The Repair Stem Cells Institute is the worlds only stem cell patients advocacy group whose mission is to Educate, Advocate, and Empower people to make educated choices about their medical conditions and treatments in order to lead longer and more fulfilling lives. The Double Benefits for SCI program marks a milestone in RSCIs seven years of educating thousands and guiding hundreds to adult stem cell therapies by the worlds most competent stem cells doctors at 14 affiliated international stem cell treatment centers.

Highlights of RSCIs stem cell treatment for Spinal Cord Injury include:

An RSCI Spinal Cord Injury patient, Graham Faught, who received treatment in 2013 at the Florida treatment clinic, said, This treatment literally got me back on my feet. In April, I was confined to a wheelchair with little hope. By December, I was upright again, making some progress on the treadmill and hopeful for the future. Late Flash: March 20, Graham walked 20 feet with a walker. We expect to have videos soon.

Don Margolis, founder and chairman of the Repair Stem Cells Institute (http://www.repairstemcells.org), stated, We at RSCI are very proud to offer this incredible program for SCI patients. We are confident that it will be in the forefront of many more such treatment breakthroughs. Our next target for the summer of 2014 is a double for Multiple Sclerosis, hopefully at the same price!

Currently, adult stem cell treatments are being used to help patients recover from over 150 debilitating chronic conditions previously thought to be untreatable, including the Big Three Heart Disease, Diabetes, and Cancer -- as well as Alzheimers, Parkinsons, Spinal Cord Injury, Liver Disease, Cerebral Palsy, Renal Failure, Arthritis, Autism, and Diabetes. A full list of diseases stem cells can help can be found on the RSCI website (http://www.repairstemcells.org). To date, commercial stem cell treatments have been used by over 30,000 patients with a 65% success rate.

YORK, Pa. (AP) - A York County soldier left partially paralyzed when he was shot in Afghanistan nearly two years ago is banking on stem cells to help him regain movement.

Matthew Hanes, 22, of Manchester Township will head to China in April to undergo surgery to repair part of his damaged spinal cord.

Doctors essentially will use minor surgery and stem cell therapy to build a bridge over two vertebrae that were shattered when Hanes was shot.

At the minimum Ill get at least some feeling back where I dont have it in certain places, but I could get everything back if it goes well, Hanes said.

U.S. Army Cpl. Hanes was shot while on patrol in Afghanistan in June 2012. He was left with limited use of his upper body and no use of his lower extremities.

RESEARCH: Soon after he returned to the U.S., Hanes began researching stem cell therapy as possible treatment.

Thats how he found Puhua International Hospital in Beijing, where he will fly on April 1 for the treatment. Hes slated to return stateside later that month.

Its coming up slowly now that I know its on, Hanes said.

During his research, Hanes said he found the U.S. is so far behind on stem cell research compared to some countries in Asia, such as China, and Europe.

For years, the federal government imposed tight restrictions on stem cell research until it was loosened in 2009 by President Barrack Obama.

PITTSBURGH, March 18, 2014 Stem cells derived from human muscle tissue were able to repair nerve damage and restore function in an animal model of sciatic nerve injury, according to researchers at the University of Pittsburgh School of Medicine. The findings, published online today in the Journal of Clinical Investigation, suggest that cell therapy of certain nerve diseases, such as multiple sclerosis, might one day be feasible.

To date, treatments for damage to peripheral nerves, which are the nerves outside the brain and spinal cord, have not been very successful, often leaving patients with impaired muscle control and sensation, pain and decreased function, said senior author Johnny Huard, Ph.D., professor of orthopaedic surgery, and Henry J. Mankin Chair in Orthopaedic Surgery Research, Pitt School of Medicine, and deputy director for cellular therapy, McGowan Institute for Regenerative Medicine.

"This study indicates that placing adult, human muscle-derived stem cells at the site of peripheral nerve injury can help heal the lesion," Dr. Huard said. "The stem cells were able to make non-neuronal support cells to promote regeneration of the damaged nerve fiber."

The researchers, led by Dr. Huard and Mitra Lavasani, Ph.D., first author and assistant professor of orthopaedic surgery, Pitt School of Medicine, cultured human muscle-derived stem/progenitor cells in a growth medium suitable for nerve cells. They found that, with prompting from specific nerve-growth factors, the stem cells could differentiate into neurons and glial support cells, including Schwann cells that form the myelin sheath around the axons of neurons to improve conduction of nerve impulses.

In mouse studies, the researchers injected human muscle-derived stem/progenitor cells into a quarter-inch defect they surgically created in the right sciatic nerve, which controls right leg movement. Six weeks later, the nerve had fully regenerated in stem-cell treated mice, while the untreated group had limited nerve regrowth and functionality. Twelve weeks later, treated mice were able to keep their treated and untreated legs balanced at the same level while being held vertically by their tails. When the treated mice ran through a special maze, analyses of their paw prints showed eventual restoration of gait. Treated and untreated mice experienced muscle atrophy, or loss, after nerve injury, but only the stem cell-treated animals had regained normal muscle mass by 72 weeks post-surgery.

"Even 12 weeks after the injury, the regenerated sciatic nerve looked and behaved like a normal nerve," Dr. Lavasani said. "This approach has great potential for not only acute nerve injury, but also conditions of chronic damage, such as diabetic neuropathy and multiple sclerosis."

Drs. Huard and Lavasani and the team are now trying to understand how the human muscle-derived stem/progenitor cells triggered injury repair, as well as developing delivery systems, such as gels, that could hold the cells in place at larger injury sites.

Introducing the spinal cord

The spinal cord is the delicate tissue encased in and protected by the hard vertebrae of the spinal column. Together the brain and spinal cord form the bodys central nervous system.

The spinal cord is made up of millions of nerve cells that carry signals to and from the brain and out into other parts of the body. The information that allows us to sit, run, go to the toilet and breathe travels along the spinal cord.

The main cell type found in the spinal cord, the neuron, conveys information up and down the spinal cord in the form of electrical signals. An axon(also known as a nerve fibre) is a long, slender projection of a neuron that conducts these signals away from the neuron's cell body. Each neuron has only one axon, and it can be as long as the entire spinal cord, up to 45cm in an adult human.

The axons that carry messages down the spinal cord (from the brain) are called motor axons. They control the muscles of internal organs (such as heart, stomach, intestines) and those of the legs and arms. They also help regulate blood pressure, body temperature, and the bodys response to stress.

The axons that travel up the cord (to the brain) carry sensory information from the skin, joints and muscles (touch, pain, temperature) and from internal organs (such as heart and lungs). These are the sensory axons.

Neurons in the spinal cord also need the support of other cell types. The oligodendrocyte, for example, forms structures that wrap around and insulate the axon. Called myelin, this insulating material helps the electrical impulse to flow quickly and efficiently down the axon.

A spinal cord injury affects both neurons and the myelin sheath that insulates axonsWhen the spinal cord is injured, the initial trauma causes cell damage and destruction, and triggers a cascade of eventsthat spread around the injury site affecting a number of different types of cells. Axons are crushed and torn, and oligodendrocytes, the nerve cells that make up the insulating myelin sheath around axons, begin to die. Exposed axons degenerate, the connection between neurons is disrupted and the flow of information between the brain and the spinal cord is blocked.

The spine has different sections. The level of paralysis depends on the location of the injury.

ROCKVILLE, Md., March 17, 2014 /Emag.co.uk/ Neuralstem, Inc. (NYSE MKT: CUR) announced that the final results from the Phase I safety trial using NSI-566 spinal cord stem cells in the treatment of amyotrophic lateral sclerosis (ALS or Lou Gehrigs disease) were published in the peer-reviewed journal, Annals of Neurology http://onlinelibrary.wiley.com/doi/10.1002/ana.24113/full. In Intraspinal Neural Stem Cell Transplantation in Amyotrophic Lateral Sclerosis: Phase I Trial Outcomes, results were updated from Phase I interim data, reported earlier, to include data from the last six patients in the trial. These six patients were the first to receive cervical stem cell transplants. Three of them were also the first to be transplanted along the length of their spines, in both the lumbar and the cervical regions. The results showed that NSI-566 human spinal cord stem cells can be safely transplanted in both the lumbar and cervical spinal cord segments, did not accelerate disease progression, and warrant further study on dosing and therapeutic efficacy. Furthermore, the researchers were able to identify potential therapeutic windows, suggesting that more injections, as well as multiple injections, are better and may increase both the length and the magnitude of the potential benefits. This is consistent with the hypothesized neuroprotective mechanism-of-action for this cell therapy.

Photo Since concluding Phase I, the trial has progressed to Phase II at three centers, Emory University Hospital in Atlanta, Georgia, the ALS Clinic at the University of Michigan Health System, in Ann Arbor, Michigan, and Massachusetts General Hospital in Boston, Massachusetts, which treated its first patient in February. Treatment of three of the five Phase II cohorts has been completed.

Although this was a Phase I trial, and functional outcome data were collected for the purpose of assessing safety, we performed secondary analyses of these data as a means to gain insight into how cellular transplantation affected disease progression rates and to inform outcome assessment approaches in future trial phases, said Eva Feldman, MD, PhD, Director of the A. Alfred Taubman Medical Research Institute, Director of Research of the ALS Clinic at the University of Michigan Health System, principle investigator for the NSI-566/ALS trial and lead author. Dr. Feldman is also an unpaid consultant to Neuralstem.

Pre-surgical disease progression rates for the various functional outcome measures were calculated to create slopes for each patient, so that we could determine if post-surgical data points, at 6, 9, 12 and 15 months, improved relative to predicted points. We also did analyses to determine which, if any, functional outcome assessment most closely correlated with the overall ALSFRS-R scores, said Dr. Feldman. Comparison of the outcome data to predicted outcome points in group E (patients who received both lumbar and cervical injections) revealed improvements in a significant number of measures at 6, 9, 12 and 15 months post-surgery. Overall, 50% of the patients in the trial showed improvement across multiple clinical measures at the same time points. We also found that a measure of grip strength correlated most closely with the overall ALSFRS-R scores.

Dr. Feldman added, Finally, we conducted an analysis to identify the most biologically active period of the injected cells for the patients receiving both lumbar and cervical injections. This analysis reveals that the maximal periods of benefit correlate with the two surgical interventions. Importantly, as the bell-shaped curve associated with each intervention is likely due to disease progression, increasing the total cell dose, and applying multiple applications of these stem cells, may increase both the length and magnitude of the potential benefit. We are of course exploring this very dosing regimen in our ongoing Phase II trial.

The completion of this Phase I study is a major milestone for the testing of intraspinal stem cell therapy for ALS, said Jonathan Glass, MD, Professor of Neurology and Pathology, Emory University School of Medicine and Director of the Emory ALS Center, site principal investigator and a senior study author. We have now shown that the procedure is safe for both lumbar and cervical injections, allowing us to move forward with an aggressive program to test whether this treatment will improve the course of disease for patients with ALS.

This peer-reviewed article is the first such report of cervical and dual-targeted intraspinal transplantation of neural stem cells in ALS subjects, said Karl Johe, PhD, Neuralstems Chairman of the Board and Chief Scientific Officer. We believe our cells offer a means to replace lost cells, provide neurotrophic support, and improve the diseased microenvironment. This study demonstrates these factors, and that the cells and the novel surgical route of administration are safe and well-tolerated. Our ability to directly inject cells into the cervical regions of the spinal cord represents a significant advance in the field of cell therapy.

We would like to thank the incredible teams at both Michigan and Emory who made this study possible, and who continue working with us today in our ongoing Phase II trial. Wed like to give special thanks to Dr. Jonathan Glass, Director of the Emory ALS Center, the Emory site principle investigator, and Dr. Nick Boulis, Associate Professor of Neurosurgery at Emory School of Medicine, the surgeon for all of the Phase I surgeries, and the inventor of the spinal-mounted stabilization and injection platform and floating cannula surgical devices used to deliver the cells, concluded Dr. Johe.

Because neurons (nerve cells) in the central nervous system (the brain and spinal cord) do not repair or replace themselves after being injured, researchers are investigating whether transplanting cells into an injured area can restore function.

One of the many challenges for researchers is obtaining cells that will function as neurons in the brain or spinal cord. Because a persons body doesnt have spare neurons for transplantation, efforts are being made to find other cells that can be transformed into neurons. One potential source is stem cells from human embryos. Less than a week after conception cells in an embryo begin to differentiate that is, they begin to form specific types of cells, such as bone cells, red blood cells, heart muscle cells, and so on. Stem cells are simply cells that can differentiate into other types of cells. Early in the life of an embryo stem cells have the potential to differentiate into the more than two hundred types of cells in a human body. There are other kinds of stem cells, including stem cells in adults, which can differentiate into a more limited number of types of cells.

Using embryonic stem cells for transplantation is controversial because it is necessary to first create human embryos to produce the stem cells and then kill the embryos in the process of harvesting the stem cells. Opponents of the process contend that it is unethical or immoral to create and then kill any form of human life for the purpose of harvesting stem cells. Proponents of stem cell transplantation either claim that embryos created in a laboratory have no value or significance apart from producing stem cells or that the end of helping injured or ill people justifies the means of creating and then killing human life.

Apart from the controversy about creating and killing human embryos, stem cell researchers are faced with another challenge which is partly practical and partly ethical. The bodys immune system recognizes what is part of the body and what is not. Every cell in the body has protein molecules on the surface of the cell wall that identify the cell as being part of the body (these are known as human leukocyte antigens (HLA)). These markers are recognized by the cells in our immune systems. If the immune system doesnt detect the bodys specific markers, it will sound the alarm and go on the attack. This allows our immune system to recognize and fight invaders in the form of bacteria, viruses, and fungi, protecting us from diseases that would otherwise kill us.

However, this same ability of the immune system presents a serious problem when tissue from another person (or animal) is transplanted into the body. The immune system will ordinarily identify the transplant as foreign and begin to attack it. The attack is carried out by cells using chemical weapons that can kill other cells. This process is known as transplant rejection.

To prevent rejection two different strategies have been used. One is to find a transplant donor who has genetic markers (HLA) that are similar to those of the person receiving the transplant. The more similar the markers, the less likely it is that the immune system will reject the transplant. The other strategy is to administer drugs to transplant recipients that suppress the ability of the immune system to recognize and target transplants for destruction. While these drugs usually work, they have numerous side-effects and can make an individual more vulnerable to infections. Often times both strategies are used.

One potential solution to the problem of transplant rejection would be to create a transplant with markers identical to those of the person receiving the transplant. A persons DNA contains the unique blueprint for that persons body, including the details for the markers (HLA) that are recognized by the immune system. Some researchers are attempting to insert human DNA into cells that are then used to create human embryos. This process is known as cloning that is, artificially producing another organism with DNA that is identical to the DNA of the donor. Cloning has been performed with some types of animals but not with a human being(1). If human cloning is eventually successful, the clone would have markers identical to those of the DNA donor. This would potentially allow transplants to be created with the DNA of the patient, which would be recognized by the immune system as belonging to the body. There would be no potential for transplant rejection and no need for drugs to suppress the immune system.

However, even if cloning is successful, researchers will still need to learn how to stimulate an embryonic stem cell to produce a neuron rather than a skin cell or some other type of cell. Transplanting undifferentiated stem cells runs the risk of creating a tumor, an event which has actually occurred when embryonic stem cells have been transplanted into mice. Furthermore, while finding a source of cells that can differentiate into neurons is one major challenge in developing a cure for spinal cord injuries, there are others (click on the Treatments for the Future link under the Spinal Injury Treatment tab.) Consequently, any effective treatment to repair spinal cord injuries using embryonic stem cells lies years, if not a decade or more, in the future.

Cloning is one example of genetic engineering, an activity in which people manipulate DNA to create organisms that wouldnt otherwise exist in nature. While the first mammal (Dolly the sheep) was cloned in 1997, some clones have had health problems not characteristic of the species (including Dolly), are more prone to have offspring with birth defects, or have much shorter than normal life spans. The long term results of cloning are not known. As a result, ethical issues abound, and particularly when human cloning is the issue.

Stem Cell Research in pursuit of Spinal Cord Injury ...

Research from Karolinska Institutet in Sweden suggests that the expression of the so called MYC gene is important and necessary for neurogenesis in the spinal cord. The findings are being published in the journal EMBO Reports.

The MYC gene encodes the protein with the same name, and has an important role in many cellular processes such as proliferation, metabolism, cell death and the potential of differentiation from immature stem cells to different types of specialized cells. Importantly it is also one of the most frequently activated genes in human cancer.

Previously MYC has been shown to promote proliferation and inhibit differentiation in dissociated cells in culture. However, in the current study researchers demonstrate that in the intact neural tissue from chickens, MYC promotes differentiation of neural cells rather than their proliferation.

"We hope that this news knowledge can be important for developing future strategies to promote nerve cell development, for example in patients with spinal cord injuries," says principal investigator Marie Arsenian Henriksson, professor at the Department of Microbiology, Tumor and Cell Biology at Karolinska Institutet.

New findings on neurogenesis in spinal cord

Cells have a metabolism that can be altered according to its function. If cellular metabolism is disturbed, it can lead to disease of the entire organism. Researchers at the Vetmeduni Vienna discovered that the uncoupling proteins UCP2 and UPC4 are involved in different types of cellular metabolism. As a result, cell alterations can now be detected much earlier than was thus far possible. This research work was recently published in the PLOS ONE journal.

UCPs or uncoupling proteins are present in mitochondria, the powerhouse of each cell in the body. The functions of most of the five known UCPs remain mysterious (UCP2-UCP5), whereby only the distinct function for UCP1 has thus far been discovered. UCP1 is responsible for heat production when muscle activity is deficient such as is the case with babies and animals in hibernation. The research team at the Department of Physiology and Biophysics at the University of Veterinary Medicine in Vienna were able to provide a fundamental explanatory concept for the function of UCP2 and UPC4 for the first time. Each of these proteins are involved in different types of cell metabolism.

UCP2 in Stem Cells and Cancer Cells

In earlier studies of immune cells, lead author, Anne Rupprecht, had already shown that UCP2 could be involved in increased metabolism. Embryonic stem cells precisely exhibit such an increased metabolism, as they rapidly and continually divide, just like cancer cells. Rupprecht searched for various UCPs in embryonic stem cells of mice and in effect found UCP2. "Very high amounts of UCP2 even indicated an especially strong increase in metabolism. In other studies UCP2 had also already been detected in cancer cells", according to Rupprecht.

UCP4 in Nerve Cells

In contrast to UCP2, UCP4 is only found in nerve cells. Nerve cells have a completely different metabolism. They seldom divide, unlike stem cells and cancer cells. The research team of Prof. Elena Pohl therefore examined embryonic stem cells that differentiated to nerve cells in culture. On the basis of this model system, the researchers could show that UCP2 is still existent in the quickly reproducing stem cells, yet at the moment of differentiation are replaced by UPC4.

"In our work, we have examined the natural process of cell differentiation from stem cells to neurons. We know that metabolism changes during differentiation. The fact that we found UCP2 in one case and in the other UCP4 proves for the first time that these proteins are associated with varying types of cell metabolism", specified Elena Pohl.

The researchers, for example, found only UCP2 in neuroblastoma cells - nerve cells that have malignant changes. UCP4, the usual protein of nerve cells was not detectable. UPC4 apparently got lost in the changed nerve cells that were on their way to becoming rapidly reproductive cancer cells.

Hot on the trail of cellular metabolism: Researchers unravel the function of cell proteins

They used a process similar to one they used in an earlier project published last September where they reported creating neural networks in the brains of mice. In both cases the researchers reprogrammed the nerve support cells known as astrocytes into functional nerves. Astrocytes tend to be abundant, particularly at the site of injury where they proliferate and form scar tissue that actually prevents regrowth of the damaged nerves.

The Texas teams first step involved using a biologic substance to manipulate the expression of genes in the astrocytes at the site of spinal injury in the mice. They tried 12 different ones before they found one that is efficient in turning the protective cells into progenitor cells for nerves; think of them as middlemen between nerve stem cells and adult nerve. They then used a common drug called valproic acid to encourage those progenitor cells to mature into functioning nerves.

The work seems to map out a strategy to get new nerve growth directly in patients, or in vivo. The paper was published in Nature Communication and a press release from the university was picked up by ScienceCodex and it quoted the senior researcher Chun-Li Zhang on the impact:

CIRM Stem Cell Research Updates: Team tricked scar tissue ...

The video begins like a clip from a James Bond movie, where the billionaire tycoon announces his plan to save humanity.

"Since the dawn of time, great men have challenged the status quo and dared to dream," an off-screen female narrator says in a sultry British accent while images of Leonardo da Vinci, Martin Luther King and other great historical figures parade across the screen.

The great man in question is none other than Peter Nygrd, the Helsinki-born, Manitoba-raised fashion magnate best known as the founder of Nygrd International.

And his plan to save humanity? Use stem-cell research to cure diseases and live forever, just as you would expect a billionaire tycoon to declare in a Bond movie.

In a 10-minute YouTube video titled Bahamas Stem Cell Laws: The Peter Nygrd Breakthrough, the 70-year-old former Winnipegger claims to be at the forefront of scientific and legislative efforts to further the achievements of stem-cell research.

Nygrd claims to have lobbied the Bahamian government to further stem-cell research, though the Bahamas Weekly reported the island nation's attorney general denied the billionaire was involved in drafting legislation.

That alone is fascinating, but Nygrd isn't just a stem-cell advocate. He says he's personally involved in the research by receiving injections of his own cells grown in Peter, or rather, petri dishes.

Yes, Nygrd claims he is actually getting younger. In his video, he calls stem-cell research a game-changer for humanity.

"This could eliminate all disease. This perhaps is immortality," he breathlessly states in a video that appears entirely serious.

"Ponce de Leon had the right idea. He was just too early," Nygrd continues, referring to the 16th-century conquistador who searched for the fountain of youth. "That was then. This is now."

Nygrd uses stem cells to pursue immortality

UT Southwestern Medical Center researchers created new nerve cells in the brains and spinal cords of living mammals without the need for stem cell transplants to replenish lost cells.

Although the research indicates it may someday be possible to regenerate neurons from the body's own cells to repair traumatic brain injury or spinal cord damage or to treat conditions such as Alzheimer's disease, the researchers stressed that it is too soon to know whether the neurons created in these initial studies resulted in any functional improvements, a goal for future research.

Spinal cord injuries can lead to an irreversible loss of neurons, and along with scarring, can ultimately lead to impaired motor and sensory functions. Scientists are hopeful that regenerating cells can be an avenue to repair damage, but adult spinal cords have limited ability to produce new neurons. Biomedical scientists have transplanted stem cells to replace neurons, but have faced other hurdles, underscoring the need for new methods of replenishing lost cells.

Scientists in UT Southwestern's Department of Molecular Biology first successfully turned astrocytes -- the most common non-neuronal brain cells -- into neurons that formed networks in mice. They now successfully turned scar-forming astrocytes in the spinal cords of adult mice into neurons. The latest findings are published today in Nature Communications and follow previous findings published in Nature Cell Biology.

"Our earlier work was the first to clearly show in vivo (in a living animal) that mature astrocytes can be reprogrammed to become functional neurons without the need of cell transplantation. The current study did something similar in the spine, turning scar-forming astrocytes into progenitor cells called neuroblasts that regenerated into neurons," said Dr. Chun-Li Zhang, assistant professor of molecular biology at UT Southwestern and senior author of both studies.

"Astrocytes are abundant and widely distributed both in the brain and in the spinal cord. In response to injury, these cells proliferate and contribute to scar formation. Once a scar has formed, it seals the injured area and creates a mechanical and biochemical barrier to neural regeneration," Dr. Zhang explained. "Our results indicate that the astrocytes may be ideal targets for in vivo reprogramming."

The scientists' two-step approach first introduces a biological substance that regulates the expression of genes, called a transcription factor, into areas of the brain or spinal cord where that factor is not highly expressed in adult mice. Of 12 transcription factors tested, only SOX2 switched fully differentiated, adult astrocytes to an earlier neuronal precursor, or neuroblast, stage of development, Dr. Zhang said.

In the second step, the researchers gave the mice a drug called valproic acid (VPA) that encouraged the survival of the neuroblasts and their maturation (differentiation) into neurons. VPA has been used to treat epilepsy for more than half a century and also is prescribed to treat bipolar disorder and to prevent migraine headaches, he said.

The current study reports neurogenesis (neuron creation) occurred in the spinal cords of both adult and aged (over one-year old) mice of both sexes, although the response was much weaker in the aged mice, Dr. Zhang said. Researchers now are searching for ways to boost the number and speed of neuron creation. Neuroblasts took four weeks to form and eight weeks to mature into neurons, slower than neurogenesis reported in lab dish experiments, so researchers plan to conduct experiments to determine if the slower pace helps the newly generated neurons properly integrate into their environment.

In the spinal cord study, SOX2-induced mature neurons created from reprogramming of astrocytes persisted for 210 days after the start of the experiment, the longest time the researchers examined, he added.

Spinal cord injuries can lead to an irreversible loss of neurons, and along with scarring, can ultimately lead to impaired motor and sensory functions. Scientists are hopeful that regenerating cells can be an avenue to repair damage, but adult spinal cords have limited ability to produce new neurons. Biomedical scientists have transplanted stem cells to replace neurons, but have faced other hurdles, underscoring the need for new methods of replenishing lost cells.

Scientists in UTSouthwesterns Department of Molecular Biology first successfully turned astrocytes the most common non-neuronal brain cells into neurons that formed networks in mice. They now successfully turned scar-forming astrocytes in the spinal cords of adult mice into neurons. The latest findings are published today in Nature Communications and follow previous findings published in Nature Cell Biology.

Our earlier work was the first to clearly show in vivo (in a living animal) that mature astrocytes can be reprogrammed to become functional neurons without the need of cell transplantation. The current study did something similar in the spine, turning scar-forming astrocytes into progenitor cells called neuroblasts that regenerated into neurons, said Dr. Chun-Li Zhang, assistant professor of molecular biology at UTSouthwestern and senior author of both studies.

Astrocytes are abundant and widely distributed both in the brain and in the spinal cord. In response to injury, these cells proliferate and contribute to scar formation. Once a scar has formed, it seals the injured area and creates a mechanical and biochemical barrier to neural regeneration, Dr. Zhang explained. Our results indicate that the astrocytes may be ideal targets for in vivo reprogramming.

The scientists' two-step approach first introduces a biological substance that regulates the expression of genes, called a transcription factor, into areas of the brain or spinal cord where that factor is not highly expressed in adult mice. Of 12 transcription factors tested, only SOX2 switched fully differentiated, adult astrocytes to an earlier neuronal precursor, or neuroblast, stage of development, Dr. Zhang said.

In the second step, the researchers gave the mice a drug called valproic acid (VPA) that encouraged the survival of the neuroblasts and their maturation (differentiation) into neurons. VPA has been used to treat epilepsy for more than half a century and also is prescribed to treat bipolar disorder and to prevent migraine headaches, he said.

REGINA Meeting Rick Hansen during his Man in Motion world tour sparked six-year-old Josef Buttigiegs fascination with biology and set his career course in motion.

Twenty-eight years after first meeting Hansen, Buttigieg is a biology professor at the University of Regina. Recently he received a $100,000 grant over two years from the Saskatchewan Health Research Foundation (SHRF) to improve the lives of people with spinal cord injuries.

One day Buttigieg hopes hes able to heal his hero.

He vividly recalls hearing Hansen speak at his elementary school in Toronto and talking with him afterwards.

I was really curious about how being in a car accident can result in a spinal cord injury or not being able to walk I just couldnt fathom that, Buttigieg said.

During his first year at McMaster University in Hamilton, Buttigieg again crossed paths with Hansen when he spoke at the university during a ceremony where he received an honorary doctorate.

Further inspired, Buttigieg became a volunteer research student in a spinal cord injury lab at McMaster before pursuing graduate studies there. He went on to work with a prominent neurosurgeon specializing in spinal cord injuries before arriving at the U of R in 2011 and starting his research program.

One of the focuses of Buttigiegs research is stem cell regeneration for spinal cord injuries, stroke and multiple sclerosis.

In terms of the damage to the nervous system, its very similar between the three cases, he said.

When a spinal cord is healthy, a signal is sent from the brain to the nerve, and then the nerve is turned off.

A new study describes the complexity of the new T cell repertoire following immune-depleting therapy to treat multiple sclerosis, improving our understanding of immune tolerance and clinical outcomes.

In the Immune Tolerance Network's (ITN) HALT-MS study, 24 patients with relapsing, remitting multiple sclerosis received high-dose immunosuppression followed by a transplant of their own stem cells, called an autologous stem cell transplant, to potentially reprogram the immune system so that it stops attacking the brain and spinal cord. Data published in the Journal of Clinical Investigation quantified and characterized T cell populations following this aggressive regimen to understand how the reconstituting immune system is related to patient outcomes.

ITN investigators used a high-throughput, deep-sequencing technology (Adaptive Biotechnologies, ImmunoSEQTM Platform) to analyze the T cell receptor (TCR) sequences in CD4+ and CD8+ cells to compare the repertoire at baseline pre-transplant, two months post-transplant and 12 months post-transplant.

Using this approach, alongside conventional flow cytometry, the investigators found that CD4+ and CD8+ lymphocytes exhibit different reconstitution patterns following transplantation. The scientists observed that the dominant CD8+ T cell clones present at baseline were expanded at 12 months post-transplant, suggesting these clones were not effectively eradicated during treatment. In contrast, the dominant CD4+ T cell clones present at baseline were undetectable at 12 months, and the reconstituted CD4+ T cell repertoire was predominantly composed of new clones.

The results also suggest the possibility that differences in repertoire diversity early in the reconstitution process might be associated with clinical outcomes. Nineteen patients who responded to treatment had a more diverse repertoire two months following transplant compared to four patients who did not respond. Despite the low number of non-responders, these comparisons approached statistical significance and point to the possibility that complexity in the T cell compartment may be important for establishing immune tolerance.

This is one of the first studies to quantitatively compare the baseline T cell repertoire with the reconstituted repertoire following autologous stem cell transplant, and provides a previously unseen in-depth analysis of how the immune system reconstitutes itself following immune-depleting therapy.

StemCells, Inc. Expands Phase I/II Spinal Cord Injury Trial to North America

NEWARK, Calif., Jan. 10, 2014 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM) announced today that a team at the University of Calgary successfully transplanted its first subject in the Company's Phase I/II clinical trial in chronic spinal cord injury, with the Company's proprietary HuCNS-SC human neural stem cells. The ninth subject to enroll in the trial, which was initiated in Switzerland, is the first spinal cord injury patient to have undergone transplantation in North America. This expansion from a single-site, single-country study to a multi-site, multi-country program accelerates the current trial, which should complete enrollment of the remaining three patients this quarter, and pave the way for a controlled Phase II efficacy study that StemCells, Inc. plans to initiate mid-year to further investigate its HuCNS-SC product candidate as a treatment for spinal cord injury.

"With this transplantation in Canada, we have the first international trial investigating neural stem cells for spinal cord injury," said Stephen Huhn, M.D., FACS, FAAP, Vice President, CNS Clinical Research at StemCells, Inc. "The 12-month data from the first cohort has demonstrated a favorable safety profile, and sensory gains first detected in two of the three subjects at the six-month assessment have persisted. The third subject remains stable. We are extremely encouraged with the progress of our spinal cord injury program and the transition into an international study will accelerate completion of enrollment."

Steve Casha, M.D., Ph.D., FRCSC, the principal investigator at the University of Calgary, added, "We are proud to be the first center to enroll a subject in North America. This important research is yielding critical insight into the use of stem cells in treating spinal cord injury patients. The results should serve as a solid foundation for the Company's planned Phase II controlled efficacy study and represents an important step in the development of this promising technology."

"We have closely followed the conduct of the StemCells, Inc. trial at the University of Zurich, under the direction of Dr. Armin Curt," said Michael Fehlings M.D., Ph.D., FACS, FRCSC. Dr. Fehlings is Medical Director of the Krembil Neuroscience Centre, Professor of Neurosurgery at the University of Toronto, head of the Spinal Program at the Toronto Western Hospital, and principal investigator for the trial at the University of Toronto. "There is a large unmet medical need for treatments in spinal cord injury. The opening of sites in North America is great news for the worldwide community of patients and their families, as well as for researchers. There is a strong rationale to explore novel therapeutic approaches to treating spinal cord injury, and we are pleased to be working with StemCells at the forefront of this trailblazing study."

About the StemCells, Inc. Spinal Cord Injury Clinical Trial

The Company's Phase I/II clinical trial is designed to assess both safety and preliminary efficacy of HuCNS-SC cells as a treatment for chronic spinal cord injury. The Company plans to enroll 12 subjects with thoracic (chest-level) neurological injuries at the T2-T11 level, classified as complete or incomplete according to the American Spinal Injury Association Impairment Scale.

To date, nine patients have been enrolled and transplanted with HuCNS-SC cells.Each of the first three subjects suffered a complete injury prior to enrolling in the study. Twelve months after transplantation of the HuCNS-SC cells, data showed multi-segment gains in sensory function in two of the first three subjects, one of which converted from a complete injury classification to an incomplete injury.The third subject in this cohort remained stable, 12 months after transplantation. The company expects to report additional interim data on both the first and second cohorts by mid-2014.

The trial is currently enrolling spinal cord injury patients at three centers: the University of Calgary; the University of Toronto; and at Balgrist University Hospital, University of Zurich, a world-leading medical center for spinal cord injury and rehabilitation. Patients who may qualify and are interested in participating in the study in North America should contact the University of Calgary at 403-944-4334 or the University of Toronto at 416-603-5285. For information on enrollment in Switzerland, interested parties may contact the study nurse either by phone at +41 44 386 39 01, or by email at stemcells.pz@balgrist.ch.

All subjects who enroll in the trial will receive HuCNS-SC cells through direct transplantation into the spinal cord and will undergo temporary treatment with immunosuppressive drugs.Evaluations will be regularly performed in the post-transplant period in order to monitor and assess the safety of the HuCNS-SC cells, the surgery and the immunosuppression, as well as to measure any change in neurological function.Preliminary efficacy will be evaluated based on defined clinical endpoints, such as changes in sensation, motor function and bowel/bladder function.The Company intends to follow the effects of this intervention long term, and each of the subjects will be invited to enroll in a separate four-year observational study after completing the Phase I/II study.In addition, the Company plans to initiate a controlled Phase II efficacy trial in in spinal cord injury in 2014.

Junior middleweight Boyd Melson has a fight scheduled for tomorrow night at the Roseland Ballroom in Manhattan against Donald Ward. Its a fight that Melson (13-1-1, 4 KOs) says he expects will be difficult, despite Ward being a late replacement for veteran Mike Ruiz. Its a fight, however, thats relatively small in relation to the one Melson fights on a daily basis.

Thats because Melson, an Army captain in the U.S. Army Reserves, is also battling a much tougher foe: spinal cord injuries. As a boxer who donates his full purses to spinal cord research, its easy to say he has a dog in this fight and its one where hes continuing to punch, despite the odds.

Were trying to bring awareness to spinal cord injuries and fund a clinical trial to happen here in the U.S, explained Melson. Theres a clinical trial thats going to be happening at the end of this year that a doctor named Dr. Wise Young is working on. Hes doing a trial here hopefully in New York and New Jersey, before this year is out, where hes going to be using umbilical cord cells and injecting them into the spinal cord. He already did this in China and hes using that data to get FDA approval here.

15 out of the 20 patients he did that were paralyzed after seven years, one of them was as long as 19 years paralyzed, Melson continued. But 15 out of the 20 are walking now with a walker and no human assistance. Its out of this world. Its a miracle. Its real frustrating for me to know that in another part of the world we may have a cure for this and its not here yet. It stinks.

Despite his being profiled in a series of publications and television programs, Melson said theres still a way to go in matching the awareness of the issue to a potential cure.

Its still a big fight, he admitted. Maybe, locally in New York people know about it. Or theyll just know that I donate my purses. A lot of them think its stem cell research, which is not correct. That happened because theyre taking stem cells from the umbilical cord for this study but theyre adult stem cells. They were donated after the baby was born. But there are plenty of different types of therapies people are using, going outside stem cells. This one just happens to be using it but its to cure paralysis, not to study stem cells.

Melson isnt alone in his aim to obtain more spinal cord injury research and has even secured the support of a series of other fighters, including Steve Cunningham, Demetrius Andrade, Deandre Latimore, Edgar Santana and Danny Jacobs on his Team Fight to Walk.

Those are some pretty strong names right there, he said.

Hes right.

Up To 500,000 Spinal Cord Injuries Per Year Worldwide The World Health Organization says as many as 500,000 people suffer spinal cord injuries every year. And it says people with such injuries are much more likely to die early. Recently, the World Health Organization released a report called International Perspectives on Spinal Cord Injuries. Alana Officer works at the WHO. She says spinal cord injuries do more than just cause paralysis, or lack of movement. There are a lot more associated health problems, such as difficulty with bowel and bladder function, difficulty with sexual function, associated problems around mental health conditions. So its much broader than just experiencing paralysis. Alana Officer is the WHOs Coordinator for Disability and Rehabilitation. She says the main causes of spinal cord injuries are traffic accidents, falls and violence. She says some causes are more common in certain areas. For example, road traffic crashes are the main contributors of spinal cord injury in Africa and the Western Pacific region. Falls tend to be the leading cause in Southeast Asia and the Middle East. And then we have high rates of violence in certain countries. We have high rates in the U.S. We have high rates in South Africa. And then weve also got the non-traumatic causes of spinal cord injuries, such as tumors and cancers, tuberculosis and spinabifida. Most people think of tuberculosis as a lung disease. But in some African countries, it is responsible for about one third of the non-violent spinal cord injuries. The birth defect spinabifida causes damage to the spine. In severe cases, it can affect walking and daily activities. Health officials say they do not yet know the exact cause of spinabifida. But they say it may be linked to genes and the environment. Alana Officer says more men than women suffer spinal cord injuries. Theres a ratio of about two-to-one of males to females. Men tend to be more likely to experience spinal cord injury between the ages of about 20 and 29 -- women, or certainly girls much younger, between sort of 15 and 19. So thats our first peak in young people. And then we get a second peak, interestingly, in older people. And the major driver of that is falls, tumors, cancer, et cetera. She says the main reason people with spinal cord injuries are more likely to die early is lack of medical care. A lot of people with spinal cord injuries, certainly in low- and middle- income countries, do not get appropriate emergency response care. Mortality rates are very strongly affected by the quality of the health care system. For example, if youre in a low-income country, you are three times more likely of dying in (a) hospital following a spinal cord injury than you would be in a high-income country. Ms. Officer says many of the causes of spinal cord injury deaths in poor countries are preventable. These include urinary tract infections and pressure sores, also known as bedsores. These are areas of damaged skin caused by a person staying in one position too long. Bedsores are usually not life-threatening problems in wealthy countries. People with spinal cord injuries can live pretty much the same amount of time as somebody without a spinal cord injury. Theres a slight difference, but certainly life expectancy has increased considerably in high-income countries. And its not the case in low- income countries. Experts suggest immediate action if a spinal cord injury is suspected, including immobilization of the spine, restricting its movement. The WHO says that should be followed by what it calls, care appropriate to the level and severity of the injury, degree of instability of the spine and compression of nerves. It also suggests skilled rehabilitation and mental health services. The WHO notes that up to 30 percent of people with spinal cord injuries show clinically-significant signs of depression. There is currently no cure for paralysis from spinal cord injuries, but many researchers are looking for one. Alana Officer says there is much that can be done to prevent such injuries -- including building safer roads and vehicles, reducing drinking and driving and wearing seatbelts. Other measures include improving safety in sports and the workplace, and adding window guards to windows. She says spinal cord injuries would be reduced if doctors could identify and treat tuberculosis earlier and by improving nutrition to reduce spinabifida cases. Scientists Create Lung Tissue from Stem Cells Finally, scientists have used stem cell technology to create working lung cells. Researchers say stem cells also could be used to create new drugs to treat diseases that restrict breathing. And they think the cells could one day create tissue for lung transplant operations. The research is another step toward what is being called personalized medicine. Over the past several years, scientists have used stem cells and growth factors to force the bodys master cells to create other cells. This process has created heart, intestinal, liver, nerve and insulin-producing cells as possible replacements for diseased organs.
