The existence of a vital support system of cells around stem cells in the brain explains why stem cells by themselves can't generate neurons in a lab dish, a major roadblock in using these stem cells for injury repair. "We believe these findings will have important implications for human therapy," said Chay Kuo, M.D., Ph.D., George Brumley Jr...
