Insulin-like signal needed to keep stem cells alive in adult brain

Researchers at University of California - Berkeley found an insulin-like signal necessary to keep stem cells alive in the adult brain. Blocking apoptosis genes alone is not enough, as neural stem cells also require an insulin-type signal to persist. The study suggests that manipulating the insulin pathway may be essential for re-growin...
