In Print Photo by Phil Farnsworth From Focus: Receptors Discovered that Direct Rod Cell Development HMS researchers have identified a surprising mechanism by which rod photoreceptors--specialized light-gathering cells that line the retina--develop from a pool of undifferentiated precursors. Tracy Young (left) and Connie Cepko demonstrate that a pair of neurotransmitter receptors relay the cues that tell the immature cells to develop into rods. The findings could lead to new methods of restoring or replacing these delicate cells, which are lost in retinitis pigmentosa and other blinding diseases.   Publications Online BBS Bulletin Focus HMI World HSTconnector MD-PhD Newsletter MedEd News Mentations On The Brain   Related Links InteliHealth Harvard Health Publications		Headlines HMOs May Improve Diabetes Care By Providing Home Monitors Upcoming Fourth Annual J.
