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 breathe new life into paralyzed gymnast

Ananth Rao talks passionately about his ambition of being a top-level gymnast just like his hero, Commonwealth Games gold medallist Ashish Kumar.

Every few minutes though, the 24-year-old Mysore lad pauses to express repressed sorrow. But there are no tears, just a hint of regret on his pained face as he recollects the fateful day when his dreams were cruelly snuffed out.

Ananth, like any other budding gymnast, was eager to impress at the Dasara Games in September 2010 when the state-level star mistimed a somersault during a practice routine.

Ananth’s head crashed on to the mat and he heard

Warning issued against stem cell tourism by experts

Warnings are being issued by experts of the dangers of medical tourism saying that unproven stem cell therapy overseas could leave patients worse off.

Signing up for stem cell therapy is worth the risk for many people who are suffering with conditions like spinal injury, multiple sclerosis, motor neuron or Parkinson’s disease.

A medical journal reported earlier this year that an Israeli teenager developed brain tumors after experimental injections at a Russian clinic.

There are alternate reports also of patients contracting meningitis after treatments in China.

A handbook will be released by the Australian Stem Cell Centre to help patients analyze radial stem

Video: Neural Stem Cells and CNS Disorder

What is a neural stem cell? How can they help treat neurological disorders such as Alzheimer’s disease, Parkinson’s disease, spinal cord injury, stroke, ALS (Lou Gehrig‘s Disease)? Evan Snyder of the Burnham Institute helps define neural stem cells (NSC), explaining that they are relatively inaccessible in the adult patient, but that they seem to benefit from some immunotolerance.

It follows that we may be able to use readily available lines of embryonic stem cells for therapy in neurodegenerative disease. Evan reviews current clinical applications for neural stem cells (including as a vehicle for small molecule delivery), and gives his

Stem cells: Therapy for dogs and horses could translate to humans

It may seem surprising, but more than 1,700 dogs in the USA with arthritis have already been treated with their own stem cells.

Remember the saying “Patient Heal Thyself?” We all — human and animals — carry around a stem cell repair kit that is used every day in helping heal the minor bumps, bruises, cuts and more serious injuries.

These stem cells are called “adult” stem cells and are found throughout the body. They sit there waiting for the signal that they are needed and they rush to the scene of the injury and begin the healing process.

So we really
