Brain stem cells remain dormant until needed to make more neurons but little is known about the molecular guards that keep them quiet - or 'wake' them up. Scientists from the Salk Institute for Biological Studies say they have identified the signal that prevents stem cells from doing too much proliferating, a move that protects the brain against too much cell division and ensuring a pool of neural stem cells that lasts a lifetime. read more
