Cells From The Iris May Replace Retinal Photoreceptors
by Dan Roberts November 2001 An online publication of the December 2001 publication of Nature Neuroscience has reported that, with genetic manipulation, cells from the iris may be able to replace photoreceptor cells in the retina. In recent experiments, Dr. Masatoshi Haruta of Kyoto University and colleagues took iris cells from rat eyes, then introduced [Read More]
U-M Scientist Finds Clues in the Development of Light-Sensitive Eye Cells
