On Your Last Nerve: Researchers Advance Understanding of Stem Cells

ScienceDaily (Nov. 17, 2009) — Researchers from North Carolina State University have identified a gene that tells embryonic stem cells in the brain when to stop producing nerve cells called neurons. The research is a significant advance in understanding the development of the nervous system, which is essential to addressing conditions such as Parkinson's disease, Alzheimer's disease and other neurological disorders.
