Cell transplants have successfully restored vision to mice which had lost their sight, leading to hopes people could benefit in the same way. UK scientists treated animals which had eye damage similar to that seen in many human eye diseases.
They were able to help them see again by transplanting immature retinal stem cells into their eyes.
UK experts welcomed the study, published in the magazine Nature, saying it was “stunning” research. If the results can be translated into a treatment for human eye disease, it could help the millions of people with conditions ranging from age-related macular degeneration to diabetes. – bbc
