A highly-magnified image of photoreceptors, also known as rods and cones, in the human retina.
So, here I am catching up on some journal reading, when Nature sends out an eblast touting new exciting advances in stem cell work, including a paper about the eye. Of course, I immediately jump to the site and find a research paper published online that reports on the modestly successful transplantation of precursor rod cells — cells that are more developed than stem cells but not quite mature rod cells — into mice with night blindness (congenital stationary night blindness). While vision improvement was not dramatic, the treated mice did see better in dim lighting; they were able to navigate a water maze in greatly reduced light much better than untreated mice. Read more
Steve is highly respected for his expertise and tireless commitment to finding treatments and cures for vision-robbing retinal diseases.
