ScienceDaily for July 22, 2010 reported on new stem cells.
New research, published in the journal Development, by Dr. Anthony-Samuel LaMantia, professor of Pharmacology & Physiology and director of the newly formed GW Institute for Neuroscience, and his colleagues have identified the stem cells that generate three critical classes of nerve cells -- olfactory receptors (ORNs), vomeronasal (VRNs) and gonadotropin releasing hormone (GnRH) neurons -- that are responsible for enabling animals and humans, to eat, interact socially and reproduce.
