Mice embryonic stem cells turned into retina curing blindness in the treated animal

Mice embryonic stem cells turned into retina curing blindness in the treated animal

In an article entitled, “Photoreceptor precursors derived from three-dimensional embryonic stem cell cultures integrate and mature within adult degenerate retina” published online in 21st July, 2013, issue of Nature Biotechnology, Anai Gonzalez-Cordero, and 14 associates affiliated to three Departments, Institute of Child Health, University College London, London, injected postnatal retinas into visually impaired adult mice. They previously demonstrated retinal repair and restoration of vision through transplantation of photoreceptor precursors. Researchers at the University College London have successfully transplanted light-sensitive cells from an artificial retina grown from embryonic stem cells. Employing an ingenious transplant technique researchers were able to reverse blindness in mice by injecting embryonic stem cells which turned into a retina. Being aided by rods they pick up light and send it to the brain for conversion into images. Scientists believe that in five years they would be able treat humans thereby improving their vision. This is a piece of good news for elderly patients suffering from Macular degeneration as the treatment may save their eyes from total degeneration leading to total blindness.
