Scientists genetically “reprogrammed” human skin cells to possess the same properties as those that make up the retina.

The process involved first turning them into pluripotent stem (IPS) cells, which have the potential to develop into virtually every kind of tissue in the body.

By exposing the IPS cells to a specific cocktail of chemicals, the scientists then caused them to grow into partially developed retina cells – the light-sensitive cells at the back of the eye which transmit nerve signals to the brain.
Although the work, published in the Proceedings of the National Academy of Sciences, is
