Graphene & electricity to change stem cells for nerve regrowth

Researchers looking for ways to regenerate nerves can have a hard time obtaining key tools of their trade.

Schwann cells are an example. They form sheaths around axons, the tail-like parts of nerve cells that carry electrical impulses. They promote regeneration of those axons. And they secrete substances that promote the health of nerve cells.

In other words, they’re very useful to researchers hoping to regenerate nerve cells, specifically peripheral nerve cells, those cells outside the brain and spinal cord.

But Schwann cells are hard to come by in useful numbers.

So researchers have been taking readily available and noncontroversial mesenchymal stem cells

Stem Cells For ALS

Advancements in stem cell research may one day help surgeons provide treatment for Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig’s disease, a deadly neurodegenerative disease characterized by the selective death of motor neurons.

CD133+ stem cells are known to have the capacity to differentiate into neural lineages and may provide an alternative treatment for patients suffering from ALS and other neurodegenerative diseases.

According to Newswise, Linda Kelley, Ph.D., director of the University of Utah’s Cell Therapy Facility, James Campanelli, Ph.D., of University of Utah spin-out Q Therapeutics, Inc., and Utah native Nicholas Maragakis, M.D., of The Johns Hopkins University

Geron explains stop on stem cell study

MENLO PARK, Calif., August 18, 2009 – Geron Corporation announced that its IND (Investigational New Drug application) for GRNOPC1, a cell therapy for neurologically complete, subacute spinal cord injury, has been placed on clinical hold by the FDA pending the agency’s review of new nonclinical animal study data submitted by the company. A clinical hold is an order that the FDA issues to a sponsor to delay a proposed trial or to suspend an ongoing trial.

Since filing the IND, Geron has been undertaking studies to enable dose escalation of its spinal cord injury product, and has been investigating application

Piloting stem cells presents a challenge for treatments

Complications and unanticipated side-effects that have slowed the progression of stem cell studies from the lab to the clinic could soon change, researchers say.
For a decade, stem cells have tantalized scientists and patients with their promise to regenerate damaged tissues and offer treatments for incurable diseases.

No one hears, however, about the individuals who died due to complications of surgery, said Dr. Hans Keirstead, a Canadian researcher who made a paralyzed rat walk back in 2004 by injecting its spinal cord with cells derived from human embryonic stem cells.
Keirstead’s lab at the University of California-Irvine just received approval

Video: StemCells Inc. using Neural Stem Cells for their Neuroprotective Effect

Discover StemCells, Inc. A pioneer in the field of neural stem cells, StemCells Inc was founded by the renown Irving Weissman, Fred Gage, and David Anderson. Martin McGlynn, CEO, presents StemCells Inc’s use of neural stem cells, and clinical development strategy based on the neuroprotective effect of neural stem cells.

Stem Cells Inc is preparing a BLA for NCL (a.k.a. Batten’s Disease). Martin reveals the source of the stem cells used, as well as the quantity of cells needed for the treatment of various diseases. StemCells Inc’s next clinical trials (PMD, spinal cord, macular degeneration) and milestones are also presented
