newscientist.com "A dip in a chemical cocktails has coaxed brain cells into reversing their life history and becoming neural stem cells again. Scientists were surprised how easy it was to reprogram the cells. The reprogramming is a key step towards developing medical treatments in which patients receive implants of their own tissue after it has been altered and multiplied in the lab. Rejuvenated neural stem cells could help repair the damage caused by Parkinson's disease, for example The simplicity of reprogramming the cells also challenges the assumption that a cell's fate is sealed once it begins to develop into a particular type of tissue. "It's another example in the growing realisation that cell plasticity is enormous," says Evan Snyder, an authority on neural stem cells at Harvard Medical School in Massachusetts. "It shows that dormant genetic programs can be reawakened," he says... Source: Science (vol 289, p 1754)" snip
