Via EurekAlert!: "The ability to produce neuroprotectors, proteins that protect the human brain against neurodegenerative disorders such as Parkinson's and ALS, is the holy grail of brain research. A technology developed at Tel Aviv University does just that, and it's now out of the lab and in hospitals to begin clinical trials with patients suffering from amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. ... the technology is now a patent-pending process that takes stem cells from a patient's own bone marrow and causes them to differentiate into astrocyte-like cells, which are responsible for the well-being of the brain's neurons. The cells release neurotrophic factors, or neuroprotectants, which have been shown to play a key role in reducing the progress of ALS, a debilitating disease characterized by the progressive degeneration of motor neurons, resulting in paralysis of a patient's limbs and organ function. ... In the mouse model, we were able to show that the bone marrow derived stem cells prevent degeneration in the brain following injection of selective neurotoxins. ... Researchers also demonstrated that transplantation of these cells increased the survival rate in the mouse model of ALS and significantly delayed the progress of motor dysfunction. ... The technology was licensed to BrainStorm Cell Therapeutics that has developed it into a clinical grade product called NurOwn, which is now being used in a clinical trial at Jerusalem's Hadassah Medical Center. BrainStorm Cell Therapeutics has recently struck an agreement to expand clinical trials to Massachusetts General Hospital in collaboration with the University of Massachusetts Medical School."
