NEWARK Stem cells might repair damage in a spinal cord, regenerating tissue currently considered irreparable. Electrical implants are already allowing a quadriplegic to control a robotic hand with their thoughts. And scientists are working on protein therapy that would keep a bad injury from becoming catastrophic .

These were just some of the advances in treating spinal cord injuries that were heralded at a symposium Wednesday at the University of Medicine and Dentistry of New Jersey. It was the second annual meeting of national scientists and researchers coming together in Newark to sharing their expertise.

The presentations show further advances since last years inaugural event, according to the experts.

"Everything Im seeing here is completely different than what I learned as a medical student 25 years ago," said Robert Heary, a UMDNJ neurosurgeon, the co-director of the Reynolds Family Spine Laboratory at the Spine Center of New Jersey, and the organizer of the event.

Stem cell implantation in a dozen spinal-cord patients is underway in Switzerland, according to Aileen Anderson, an associate professor of physical medicine and rehabilitation at the University of California-Irvine who has been involved in the work. She said the human clinical trial involving multipotent cells at the University of Zurich will be going through 2015 at least but stem cells advances have been moving relatively quickly.

"Cholesterol drugs took 30 years to get to market," Anderson said. "Stem cells as potential therapeutics have moved pretty quickly."

Some of the work presented variations upon a microscopic theme.

A UMDNJ team presented work in which an immune-system protein is suppressed to reduce inflammation allowing better recovery after catastrophic injury in mice. Michele Basso, a professor at the Ohio State University College of Medicine, presented work that showed rodents walking was dramatically improved after the another protein was suppressed, and they got exercise.

"We begin to see a gain of function that we wouldnt normally see," said Basso.

Still others focused on the technologies that being used to currently treat patients.

ANN ARBOR Three patients with amyotrophic lateral sclerosis will be permitted to receive a second dose of stem cells delivered directly to the spinal cord, in a clinical trial being led by the University of Michigans Eva Feldman, M.D.

The U.S. Food and Drug Administration approved the second treatment after a review concluded that the patients showed no adverse effects from their first implantation surgeries.

All have ALS, the inevitably fatal degenerative disease of the nervous system that many call Lou Gehrigs disease. They received injections directly into the lumbar, or lower, area of the spinal cord.

None of the patients experienced any long-term complications related to either the surgical procedure or the implantation of stem cells, or showed signs of rejecting the cells. And in the months following the surgery to inject the cells, none showed evidence that their ALS progression was accelerating.

These patients will receive a second implantation to the cervical, or upper, region of the spine where the nerves that control breathing reside. Most ALS patients die of respiratory failure as these nerves die or are damaged by the disease.

We believe that the cells and the route of administration are safe, said Feldman, principal investigator of the trial and the director of the UMs A. Alfred Taubman Medical Research Institute. The FDA go-ahead to bring these three patients back for re-dosing is a further validation of that.

The trial is funded by Neuralstem, to which Feldman is an unpaid consultant.

This Phase 1 safety trial, which is taking place at Emory University in Atlanta, began in January 2010. After reviewing safety data from the first 12 patients, the FDA granted approval for the trial to advance the cervical injections. Three patients so far have received injections to that area. Those to be re-dosed will come from the first cohort of 12.

Results from that cohort recently were featured in the peer-reviewed journal Stem Cells in an article authored by Feldman and her colleagues at Emory, including neurologist Jonathan Glass, M.D. and neurosurgeon Nick Boulis, M.D., who performed the implantation surgeries. Boulis, an adjunct professor at UMs Medical School and a Taubman Scholar, also developed the device used to inject the stem cells into the spinal cord, which received a notice of patent allowance from U.S. Patent and Trademark Office in October.

Regenerative medicine gets a cash boost from the nation's health ministry, but stricter regulations are needed to ensure safety

May 1, 2012

By Soo Bin Park of Nature magazine

Seoul, South Korea

The South Korean health ministry announced last month that research into stem cells and regenerative medicine will receive a funding boost of 33 billion won (US$29 million) in 2012, four times that given in 2011. Overall, six different ministries will invest 100 billion won in stem-cell research this year.

Until last year, public investment in stem cells in South Korea was relatively low and targeted mainly at basic research. But the country's Ministry of Health and Welfare is now expanding its support for clinical research on stem cells, with the money being used to link basic research to intermediate or clinical studies. The aim is to commercialize the research at an early stage.

"From the current research atmosphere and infrastructure, the government has judged that stem-cell studies are now maturing," says Hyung Min Chung, president of Seoul-based biotechnology firm Cha Bio and Diostech and an adviser on the budget plan. He adds that his company is particularly pleased that government investment decisions on developing stem-cell therapies will be made more quickly.

Target market

The government money will be allocated to two areas: rare or incurable diseases for which there is little incentive for private investment, such as spinal cord damage; and common chronic conditions, such as arthritis, for which the aim is to help South Korean companies to capture part of the large potential market for treatments.

South Korea Steps Up Stem-Cell Work

When a person suffers a heart attack, scar tissue forms over the damaged areas of the heart, reducing the organs function. However, in a recent study, scientists successfully turned this scar tissue into working heart muscle without the use of stem cells.

Duke University researchers used molecules called microRNAs to convert scar tissue (called fibroblasts) into heart muscle cells in a living mouse, improving the hearts ability to pump blood.

According to the scientists, this process is much simpler than stem cell transplants and has none of the ethical concerns, making it a potential turning point in the science of tissue regeneration.

Right now, theres no good evidence stem cells can do the job, senior author Dr. Victor Dzau, a James B. Duke professor of medicine and chancellor of health affairs at Duke University, told FoxNews.com.

Scientists believe embryonic stem cells are the best to use for tissue regeneration because they are pluripotentmeaning they can become any type of cell in the body. However, Dzau said there have not been enough experiments done to prove how functional the stem cells are in regenerating tissues and whether or not they may form deadly tumors.

Additionally, there are ethical concerns about using cells derived from a human embryo, he said.

Meanwhile, adult stem cells avoid the controversy surrounding embryonic stem cells but have a limited capacity to form other types of cells. The results of using these adult stem cells for tissue regeneration are not as satisfying as one would like, Dzau said.

Rather than stem cells, the new method developed by Dzaus team uses microRNA moleculeswhich typically control gene activityand delivers them into the scar tissue that develops after a heart attack. The microRNAs are able to reprogram, or trick, the scar tissue into becoming heart muscle again instead.

Testing is still in its early stages, but so far, the method appears to be relatively easy, and the data looks very promising, according to the researchers.

Its a much simplified, feasible way of causing regeneration; very easy to use as therapy, Dzau said. With stem cells, you have to take them from the embryo or tissue in the body, grow them in culture, and re-inject themand then there can be technical and biological problems.

JACKSONVILLE, Fla. A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified by researchers at Mayo Clinic in Florida. Their study suggests other forms of cancer may also be driven by this gene, matrix metalloproteinase-10 (MMP-10).

The study, published in the journal PLoS ONE on April 24, shows that MMP-10 is a growth factor secreted and then used by cancer stem-like cells to keep themselves vital. These cells then drive lung cancer and its spread, and are notoriously immune to conventional treatment.

The findings raise hope for a possible treatment for non-small cell lung cancer, the leading cause of U.S. cancer deaths. Researchers discovered that by shutting down MMP-10, lung cancer stem cells lose their ability to develop tumors. When the gene is given back to the cells, they can form tumors again.

The power of this gene is extraordinary, says senior investigator Alan Fields, Ph.D., the Monica Flynn Jacoby Professor of Cancer Research within the Department of Cancer Biology at Mayo Clinic in Florida.

"Our data provides evidence that MMP-10 plays a dual role in cancer. It stimulates the growth of cancer stem cells and stimulates their metastatic potential,'' he says. "This helps explain an observation that has been seen in cancer stem cells from many tumor types, namely that cancer stem cells appear to be not only the cells that initiate tumors, but also the cells that give rise to metastases."

Dr. Fields says the findings were unexpected, for several reasons.

The first is that the cancer stem cells express MMP-10 themselves, and use it for their own growth. Most of the known members of the matrix metalloproteinase genes are expressed in the tumor's microenvironment, the cells and tissue that surround a tumor, he says. The enzymes produced by these genes are involved in breaking down the microenvironment that keeps a tumor in place, allowing cancer cells to spread, which is why other genes in this family have been linked to cancer metastasis.

"The fact that a gene like MMP-10, which codes for a matrix metalloproteinase that has been linked to metastasis, is actually required for the growth and maintenance of cancer stem cells is very surprising. One would not have predicted that such a gene would be involved in this process," Dr. Fields says.

Dublin - Research and Markets (http://www.researchandmarkets.com/research/bac5f5c5/strategic_developm) has announced the addition of the "Strategic Development of Neural Stem & Progenitor Cell Products" report to their offering.

Overview: Neurogenesis is the process by which neurons are created. This process is most active during pre-natal development when neurogenesis is responsible for populating the growing brain. Neural stem cells (NSCs) are the self-renewing, multipotent cells that differentiate into the main phenotypes of the nervous system. These cell types include neurons, astrocytes, and oligodendrocytes. Neural progenitor cells (NPCs) are the progeny of stem cell division that normally undergo a limited number of replication cycles in vivo.

The terms neuronal and neural also need to be defined. Technically speaking, neuronal means pertaining to neurons, and neural means pertaining to nerves, which are the cordlike bundles of fibers made up of neurons. Since both terms ultimately are descriptive of neurons, the scientific community uses the terms "neuronal" and "neural" interchangeably. The complexity of this issue is explored from a marketing perspective within this report.

In 1992, Reynolds and Weiss were the first to isolate neural stem cells from the striatal tissue of adult mice brain tissue, including the subventricular zone, which is a neurogenic area. Since then, neural progenitor and stem cells have been isolated from various areas of the adult brain, including non-neurogenic areas like the spinal cord, and from other species, including humans. During the development of the nervous system, neural progenitor cells can either stay in the pool of proliferating undifferentiated cells or exit the cell cycle and differentiate.

This market report focuses on recent advances in NSC research applications, explores research priorities by market segment, highlights individual labs and end-users of neuronal stem cell research products, explores the competitive environment for NSC research products, and provides 5-year growth and trend analysis. It provides detailed guidance for companies that wish to offer strategically positioned NSC research products, including cells, kits, assays, and related media and reagents.

ROCKVILLE, Md., March 28, 2012 /PRNewswire/ --Neuralstem, Inc. (NYSE Amex: CUR) announced that safety results from the first 12 patients with amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) to receive its stem cells were reported online in the peer-reviewed publication, STEM CELLS, on March 13th. "Lumbar Intraspinal Injection of Neural Stem Cells in Patients with ALS: Results of a Phase I Trial in 12 Patients" (http://www.ncbi.nlm.nih.gov/pubmed/22415942.1) reports that one patient has shown improvement in his clinical status, even though researchers caution that the study was not designed to show efficacy. Additionally, there was no evidence of accelerated disease progression due to the intervention in any of the 12 patients, who were followed from 6-18 months after they were transplanted with the cells. All of the patients, who received transplants in the lumbar (lower back) region, tolerated the treatment without any long-term complications related to either the surgery or the cells.

(Logo: http://photos.prnewswire.com/prnh/20061221/DCTH007LOGO )

The 12 patients, part of the ongoing Phase I trial to evaluate the safety of Neuralstem's stem cells and transplantation procedure in patients with ALS, were the first in the world to receive intraspinal stem cell injections. Results from these patients were also were reported at the American Academy of Neurology Annual Meeting last September.

Based on a positive safety assessment, the trial has now been approved by the FDA to progress to transplanting ALS patients in the cervical (upper back) region of the spine, where the goal is to protect the motor neurons which affect respiratory function, and possibly prolong life. The fourteenth patient was transplanted earlier this month. All patients were treated at Emory University Hospital in Atlanta, Georgia.

"For these first 12 patients, we have met the objective of the Phase I trial, demonstrating safety for both the procedure of intraspinal injection and the presence of the neural stem cells in the spinal cords of ALS patients," said Jonathan Glass, MD, lead author of the publication. "We are encouraged by these results and have now advanced our trial to injections into the cervical spinal cord, targeting the motor neurons that control respiratory function." Dr. Glass is Professor of Neurology and Pathology at Emory University School of Medicine, as well as the Director of the Emory ALS Center.

"This important peer-reviewed publication reinforces our belief that we have demonstrated a safe, reproducible and robust route of administration into the spine for these spinal cord neural stem cells," said Eva Feldman, MD, PhD, Director of the A. Alfred Taubman Medical Research Institute and Director of Research of the ALS Clinic at the University of Michigan Health System. "The publication covers data up to 18 months out from the original surgery. However, we must be cautious in interpreting this data, as this trial was neither designed nor statistically powered to study efficacy." Dr. Feldman is senior author on the study, principal investigator (PI) of the ALS trial and serves as a consultant to Neuralstem as part of her University of Michigan activities.

"As this article points out, our experience in the lumbar spinal cord has been overwhelmingly positive," commented Karl Johe, PhD, study author and Neuralstem Chairman and Chief Scientific Officer. "We have already transplanted two patients in the cervical spinal cord, where we believe we can affect patients' lives the most by improving their breathing. We are in active discussions with the FDA to increase the number of cells and the number of injections as well."

"We wish to thank the teams at Michigan and Emory for the tireless efforts required to refine this breakthrough method of administration of our neural stem cells. We'd also like to thank the patients and families involved in the trial," said Richard Garr, Neuralstem CEO and President. "The progress we have made to date is both substantial, and a true team effort."

About the Study

Safety results were reported on the first 12 patients in an ongoing Phase I study to evaluate the safety of Neuralstem's spinal cord stem cells (HSSC's), as well as the transplantation technique, in the treatment of ALS (amyotrophic lateral sclerosis, or Lou Gehrig's disease).

Neuralstem ALS Stem Cell Trial Interim Results Reported in the Journal, STEM CELLS

From being unable to move the majority of his body in 2008 to taking steps with leg braces today, Mount Shastas Corben Brooks is proving that a spinal cord injury isnt the end of the world.

Three and a half years after a high school football injury left him a quadriplegic, Mount Shastas Corben Brooks is focused on recovery while in New Delhi, India, where hes receiving a third round of stem cell treatments not yet available in the United States.

The ever-optimistic 20 year old can now stand with minimal assistance, take steps with leg braces, wiggle his toes, partially close his hands and feel the majority of his legs.

Corben said hes looking forward to Labor Day Weekend, when his family will host Thunder in the Park in Mount Shasta, an event which will include the raffle drawing for a custom built motorcycle dubbed Corbens Ride, as well as live music, a chili cookoff, pancake breakfast and a poker run. Thunder in the Park will coincide with the Mount Shasta Police Departments Show & Shine car show in attempt to keep visitors in Mount Shasta the entire weekend.

Without the support of our community and countless other people I wouldn't be where I am today, Corben said via email from India last week. I can honestly say that without the help from my family, friends, this wonderful community and all who have so generously gone out of their way to help me, I would not be in the remarkable position that I am today. Thank you is nowhere near an adequate enough word to express my thanks.

Though he knows stem cell treatments are controversial, Corben said after each treatment he sees more function and sensation in his body for up to nine months after returning home.

So far on this trip I have gained new sensation and feeling in the back of my legs and hamstrings and additional feeling on my left foot, Corben said.

The results of a recent MRI also showed encouraging results, said Corben.

What we saw was the stem cells have been reducing the amount of scar tissue in my spinal cord at the injury site, Corben said. With the scar tissue being reduced, my nerves are given the opportunity to reestablish a connection. And we believe that is why I have been seeing continual recovery during and after these treatments.

Since his last visit in 2011, Corben said his walking has improved greatly, thanks to the help of his trainer back at home, Lisa Pigoni.

(KOREA HERALD/ASIA NEWS NETWORK) - A joint research team from South Korea and Germany said on Friday they have created stem cells that have the potential to help treat people suffering from dementia and spinal cord trauma.

Scientists from Konkuk University and the Max Planck Institute said they have successfully used somatic cells from mice to create so-called induced neural stem cells (iNSCs) that can be cultivated for over a year under laboratory conditions.

The iNSCs have also been injected into the brains of mice and differentiated into various nerve cells without growing into malignant tumors.

'The discovery marks the first time ordinary somatic cells have been artificially engineered to become adult stem cells,' said Prof Han Dong Wook, a professor of stem cell biology at Konkuk, who led the research.

The Gairdner Foundation announced today that Howard Hughes Medical Institute (HHMI) researchers Thomas M. Jessell and Michael Rosbash are recipients of the prestigious 2012 Canada Gairdner International Awards in recognition of their contributions to medical science.

The awards, which are presented annually, recognize scientists responsible for some of the worlds most significant medical discoveries. Jessell, who became an HHMI investigator at Columbia University in 1985, was honored for discovering basic principles of communication within the nervous system. The Foundation states that Jessells work has been instrumental in revealing important steps in the process that guides the early development of neurons, as they establish the precise connections between the spinal cord and muscles.

Rosbash, who became an HHMI investigator at Brandeis University in 1989, was highlighted for discoveries that have revealed the genetic underpinnings of the circadian clock. Circadian clocks are active throughout the bodys cells, where they use a common genetic mechanism to control the rhythmic activities of various tissues. Rosbash, Jeffrey C. Hall, emeritus professor of biology at Brandeis University, and Michael W. Young of the Laboratory of Genetics at The Rockefeller University, were honored by the Gairdner Foundation for pioneering discoveries concerning the biological clock responsible for circadian rhythms.

The Canada Gairdner Awards will be presented at a dinner in Toronto in October as part of the Gairdner National Program, a month-long lecture series given by Canada Gairdner Award winners at 21 universities from St Johns to Vancouver.

Thomas M. Jessell, Ph.D.

For the past two decades, Thomas Jessell has worked to understand how nerve cells in the developing spinal cord assemble into functional circuits that control sensory perception and motor actions. Ultimately, his research may provide a more thorough understanding of how the central nervous system is constructed and suggest new ways to repair diseased or damaged neurons in the human brain and spinal cord.

There is increasingly persuasive evidence to suggest that many neurodevelopmental and psychiatric disordersfrom motor neuron diseases to autism and schizophreniaresult from defects in the initial assembly of connections in the developing brain, says Jessell. By understanding the cellular and molecular processes that control the normal wiring pattern of these connections, we may eventually be able to design more rational and effective strategies for repairing the defects that underlie brain disorders.

Jessell's work has revealed the details of a molecular pathway that converts nave progenitor cells in the early neural tube into the many different classes of motor neurons and interneurons that assemble together to form functional locomotor circuits. This molecular pathway involves critical environmental signaling molecules such as Sonic hedgehog, and a delicate interplay of nuclear transcription factors that interpret Sonic hedgehog signals to generate diverse neuronal classes.

The principles that have emerged from Jessell's studies in the spinal cord have been found to apply to many other regions of the central nervous system, thus establishing a basic ground plan for brain development. His work has also defined many of the key steps that permit newly generated neurons to form selective connections with their target cells.

One potential strategy for brain repair involves the use of stem cells, and Jessell and his colleagues have demonstrated that mouse embryonic stem cells can be converted into functional motor neurons in a simple procedure that recapitulates the normal molecular program of motor neuron differentiation. Remarkably, these stem cell-derived motor neurons can integrate into the spinal cord in vivo and contribute to functional motor circuits. This work may uncover additional aspects of the basic program of motor neuron development, as well as pointing the way to new cell and drug-based therapies for motor neuron disease and spinal cord injury.

MCKINNEY (CBSDFW.COM) - If you have ever dealt with back pain, then you know how quickly it can take over your life. But some North Texans are discovering that tiny cells in their own bodies could be key to long-lasting relief.

A simple walk on a beautiful day is not something that Kim Ferracioli takes for granted, as the McKinney resident has been dealing with debilitating back pain for years due to a bad disk in her lower spine. It was so painful, she said. Everytime I would stand up or sit too long, it was just a horrible pinching feeling.

When steroid injections, physical therapy and a minimally-invasive surgery actually made the pain worse, Ferracioli decided to try a new therapy that is revolutionizing the way that doctors treat spinal injuries.

Were using your stem cells, which decreases the rate for complications, explained Dr. Rob Dickerman, a neurosurgeon and one of a few doctors in the country using a patients own stem cells to actually grow new bones from scratch. We can remove a disk and put them between the bones of the spine, and itll stimulate a fusion.

Dickerman removes stem cells from a patients hip and places them in a disk-like carrier. Once implanted into the patients spine, within three months, the stem cells begin to grow into new bone where the damaged disk was removed.

There was an automatic difference, said Ferracioli about the procedure. I could get up out of chairs. I didnt need the cane anymore.

Dickerman said that the success of these procedures are just the first steps for stem cell use in the spine. He hopes that they will soon be able to treat more serious injuries. If we can tweak these cells, Dickerman explained, to make it beneficial to these patients that for the most part have irreparable injuries, that would just be a huge advance in science.

Research is already underway in several labs around the world, transplanting a patients own stem cells to repair spinal cord injuries and even traumatic brain injuries. Dickerman hopes to see these treatments hit the mainstream within the next few years.

In the meantime, Ferracioli said that this new procedure is the only thing that gave her life back. I had to literally pull this back leg up the stairs, Ferracioli recalled. Now, I can just go no pain!

Stem Cells Could Be Key To Back Pain Relief

Newswise MANHATTAN, KAN. -- Research from a Kansas State University professor may make it easier to recover after spinal cord injury or to study neurological disorders.

Mark Weiss, professor of anatomy and physiology, is researching genetic models for spinal cord injury or diseases such as Parkinson's disease. He is developing technology that can advance cellular therapy and regenerative medicine -- a type of research that can greatly improve animal and human health.

"We're trying to build tools, trying to build models that will have broad applications," Weiss said. "So if you're interested in neural differentiation or if you're interested in response after an injury, we're trying to come up with cell lines that will teach us, help us to solve a medical mystery."

Weiss' research team has perfected a technique to use stem cells to study targeted genetic modifications. They are among a handful of laboratories in the world using these types of models for disease. The research is an important step in the field of functional genomics, which focuses on understanding the functions and roles of these genes in disease.

The researchers are creating several tools to study functional genomics. One such tool involves developing new ways to use fluorescent transporters, which make it easier to study proteins and their functions. These fluorescent transporters can be especially helpful when studying neurological disorders such as Parkinson's disease, stroke and spinal cord injury.

"People who have spinal cord injury do not experience a lot of regeneration," Weiss said. "It is one of the problems of the nervous system -- it is not great at regenerating itself like other tissues."

The researchers want to discover a way to help this regenerative process kick in. By studying signals from fluorescing cells, they can understand how neural stem cells are reactivated.

"We want to try and make these genetic markers, and then we can test different kinds of treatment to see how they assist in the regenerative process," Weiss said.

Weiss' stem cell research has appeared in two recent journals: Stem Cells and Development and the Journal of Assisted Reproduction and Genetics. His research has been funded by the National Institutes of Health and university funds, including the Johnson Cancer Research Center.

Weiss' seven-member research team includes a visiting professor, two full-time researchers, a graduate student and three undergraduates. He has also been collaborating with researchers from the University of Kansas Medical Center.

Doctor Wise Young in Hong Kong on February 22, 2012. Young, a leading researcher in spinal cord injuries, says China could hold the key to a cure that he has been searching for since he met late actor Christopher Reeve in the 1990s. AFP pic

US-based Doctor Wise Young first used the word cure in relation to his work after a conversation with Reeve, the Superman hero who became quadriplegic in an equestrian accident in 1995.

Reeve contacted him looking for help and the two became close friends. The actor died of heart failure in 2004 at the age of 52, having devoted his life to raising awareness about spinal cord injuries and stem-cell research.

But it was a star of a different sort, Chinese gymnast Sang Lan, who set Young on the path he believes has brought a cure closer than ever, thanks to ground-breaking clinical trials of stem-cell therapy he is conducting in China.

Everybody assumed that Im doing this in China because I wanted to escape George W. Bush, but thats not the case at all, Young said in an interview, recalling the former US presidents 2001 decision to effectively stop Federal funding of embryonic stem cell research.

I started the clinical trials in 2005 here in Hong Kong ... mainly because of a promise that I made to a young woman. Her name is Sang Lan.

Sang crushed her spine during a routine warm-up exercise at the Goodwill Games in New York in 1998. She met Young as she underwent treatment and rehabilitation in the United States over the next 12 months.

Her parents came to me and asked whether or not there would ever be a cure for her, and I said were working very hard on it, recalled Young, who was by then one of the leading US experts on spinal cord injuries.

When she went back to China after doing her rehabilitation in New York she cried and asked how would therapies go from the United States to China.

In those days China was still relatively poor and backward so she didnt think that any therapy would be coming from China. So I started in 1999 to talk to all the spinal cord doctors in China.

Philadelphia, PA, March 13, 2012 A new study suggests that administering FTY720, an oral drug that has shown promise in trials for human multiple sclerosis, significantly improves locomotor recovery in mice with spinal cord injury (SCI). The research suggests a possible new avenue to counteract the degeneration of the spinal cord in human SCI. The study will be published in the April 2012 issue of The American Journal of Pathology.

Beyond the initial tissue damage, much of the degradation of the spinal cord in SCI is due to a cascade of secondary injuries, including neuronal and glial apoptosis, inflammation, glial scar formation, local edema and ischemia, and oxidative stress. The aim of current SCI treatment is to counteract the mechanisms of secondary injury and prevent their pathological consequences, because central nervous system (CNS) neurons have very limited capacity to self-repair and regenerate.

Researchers from the Jichi Medical University School of Medicine and the Graduate School of Medicine at the University of Tokyo had previously shown that the concentration of the lysophospholipid mediator, sphingosine 1-phosphate (S1P), was significantly increased in the location of a contusion injury, triggering the migration of neural progenitor/stem cells to the site of the injury. They hypothesized that targeting S1P receptors may become a candidate therapy for various refractory central nervous system disorders, including SCI.

FTY720 acts as a broad S1P receptor modulator. Its efficacy in central nervous system disorders is believed to derive from immunomodulation. Researchers found that orally administering FTY720 to mice shortly after contusion SCI significantly improved motor function recovery. Importantly, they found that the therapeutic effects of FTY720 were not solely dependent on immune modulation. The administration of FTY720 induced lymphopenia, clearing lymphocytes from the blood, and reduced T-cell infiltration in the spinal cord. But it did not affect the early infiltration of neutrophils and activation of microglia, and it did not reduce plasma levels and mRNA expression of inflammatory cytokines in the spinal cord. Tests in mice with severe combined immunodeficiency (SCID mice) with SCI found that FTY720 significantly improved recovery of hind limb motor function.

"These data clearly indicate the importance of immune-independent functions of FTY720 in the amelioration of functional deficits after SCI in mice," explains lead investigator Yoichi Sakata, MD, PhD, Research Division of Cell and Molecular Medicine, Center for Molecular Medicine, Jichi Medical University School of Medicine.

Dr. Sakata notes that S1P receptors exist in many types of cells and play a role in many cellular processes. "We observed that FTY720 decreased vascular permeability and astrocyte accumulation in injured spinal cord. These changes were also noted in SCID mice, suggesting they are not dependent on lymphocyte function. Increased vascular permeability can lead to destruction of the blood-brain barrier in spinal cord, and astrocyte accumulation is the main cellular component of glial scar after CNS injury. FTY720 might counteract these secondary injuries and thereby prevent their pathological consequences."

"Our data suggest that targeting S1P receptors with FTY720 is an attractive therapeutic approach for SCI," Dr. Sakata concludes. "However, further evaluation utilizing larger animals such as non-human primates will be necessary to confirm its efficacy in treating SCI. Further, strategies targeted at modulating the SIP concentration in injured CNS may lead to new therapeutic approaches towards repairing various CNS disorders."

Research suggests new therapeutic approach for spinal cord injury

OKLAHOMA -- An Oklahoma House subcommittee recently approved a bill that would provide state funding for an umbilical cord blood bank. Doctors say the cord blood provides a source of stem cells without causing harm to an unborn child.

Oklahoma State Representative John Enns nearly lost his life after the Tracker he was driving rolled over, breaking his back in 3 places and leaving him paralyzed.

"Before my accident which was in 2004, I was a microbiology professor I taught about these stemcells and I taught the difference between embryonic and adult stem cells, which is huge," Enns said. "My accident happened and then I got even more involved in because this is something that may help a paralyzed person in the future with spinal cord injuries help them to actually get up and walk."

Enns now spends most his time in a wheelchair but continues to research the benefits of umbilical cord blood. He recently authored a bill that would fund a public umbilical cord blood bank for the state.

"What we will do with that is because it is pretty expensive to get it started, we will increase the amount that you pay when you get a birth certificate by $5. This will have a 5 year sunset on it which means in 5 years it will go away," Enns said.

"After the baby is delivered and the placenta is about to be thrown a way the cells can save the life of someone who has luekemia or a genetic problem where replacing their existing bone marrow is important to their cure."

OBI's president, Dr. John Armitage, says the benefits of having an umbilical cord blood bank greatly outweighs its cost..

"There is this future benefit that cant be underestimated," Armitage said. "These cells are going to eventually be used by biotechnology firms to do amazing things in terms of new tissue generation and repairing anything from hearts to any tissue in the body."

MissionIR would like to highlight Neuralstem, Inc. (NYSE AMEX: CUR). The company's patented technology enables the ability to produce neural stem cells of the human brain and spinal cord in commercial quantities, and the ability to control the differentiation of these cells constitutively into mature, physiologically relevant human neurons and glia. In addition to ALS, Neuralstem is also targeting major central nervous system conditions with its cell therapy platform, including spinal cord injury, ischemic spastic paraplegia, chronic stroke, and Huntington's disease.

In the company's news yesterday,

Neuralstem reported dosing of the fourteenth patient in its ongoing Phase I clinical trialing of the companys spinal cord neural stem cells in ALS (amyotrophic lateral sclerosis or Lou Gehrigs disease), marking the second patient to receive cells in the cervical (upper back) region of the spine and the trials first female patient. This is the first FDA-approved neural stem cell trial for the treatment of ALS.

This treatment is designed to help remediate breathing function loss associated with progressive ALS, and the transplantation of stem cells observed in the trial will be keenly watched for safety/efficacy of spinal cord neural stem cells, as well as the intraspinal transplantation method. The first twelve patients received lumbar (lower back) transplants and the trial has now been underway since January of 2010.

Having begun with non-ambulatory patients and progressing to patients able to walk, this trial has now entered into the final six patients, all of whom will receive cervical transplants, with trial conclusion projected for six months after the final surgery is complete. The proprietary CUR spinal cord delivery platform with floating cannula has helped tremendously in making this dream a possibility and represents a true breakthrough in the field, making the first ever intraspinal injections feasible.

Chairman and CSO of CUR, Karl Johe, PhD., was proud to be breaking new ground with this latest cohort of patients, as it represents a major milestone for the trial, with direct implantation of cells into the gray matter of the spinal cord in the cervical region. Dr. Johe was especially proud of the potential these successful surgeries represent for the numerous patients who suffer from significant quality of life impairment due to ALS. With the 14th successful transplant notched into their belts, CUR is confident that the demonstration of safety in this novel procedure is going quite well.

This is a huge coup for CUR which is also making significant advancements towards developing a robust cell therapy platform capable of addressing a wide range of major central nervous system conditions, ranging from spinal cord injuries and chronic stroke, to ischemic spastic paraplegia and other crippling conditions. The company has an IND submitted to FDA for Phase I safety trials in chronic spinal cord injury.

The company is also well-positioned to service systematic screening needs in the large chemical library space. With proprietary screening technology and the ability to generate appropriate human neural stem cell lines, CUR is ready to leverage discovered/patented compounds that help to stimulate brain activity and neuron regeneration. The potential exists to even reverse debilitating CNS conditions.

The company has also received FDA clearance to conduct a Phase Ib safety trial for their first small molecule compound, NSI-189, for treatment of MDD (major depressive disorder); technology that could easily pan out into schizophrenia, bipolar disorder, and Alzheimers offerings.

HONG KONG, March 7, 2012 (AFP) - One of the world's leading researchers into spinal cord injuries says China could hold the key to a cure that he has been searching for since he met late actor Christopher Reeve in the 1990s.

US-based Doctor Wise Young first used the word "cure" in relation to his work after a conversation with Reeve, the "Superman" hero who became quadriplegic in an equestrian accident in 1995.

Reeve contacted him looking for help and the two became close friends. The actor died of heart failure in 2004 at the age of 52, having devoted his life to raising awareness about spinal cord injuries and stem-cell research.

But it was a star of a different sort, Chinese gymnast Sang Lan, who set Young on the path he believes has brought a cure closer than ever, thanks to ground-breaking clinical trials of stem-cell therapy he is conducting in China.

"Everybody assumed that I'm doing this in China because I wanted to escape George W. Bush, but that's not the case at all," Young told AFP in an interview, recalling the former US president's 2001 decision to effectively stop Federal funding of embryonic stem cell research.

"I started the clinical trials in 2005 here in Hong Kong ... mainly because of a promise that I made to a young woman. Her name is Sang Lan."

Sang crushed her spine during a routine warm-up exercise at the Goodwill Games in New York in 1998. She met Young as she underwent treatment and rehabilitation in the United States over the next 12 months.

"Her parents came to me and asked whether or not there would ever be a cure for her, and I said we're working very hard on it," recalled Young, who was by then one of the leading US experts on spinal cord injuries.
