Myelin is a fatty tissue that covers the fibers between nerve cells – it’s not unlike the insulation on electrical wiring. When that tissue is compromised, the cells have difficulty communicating, and neurological diseases such as multiple sclerosis can be the result. If the myelin of MS sufferers could be regrown, then it’s possible that the disease could be cured. Recently, a team of scientists successfully regenerated myelin in mice, using human skin cells that were reprogrammed into brain cells.
