Scientists genetically â??reprogrammedâ? 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.
Study leader Dr David Gamm, from the University of Wisconsin, said: â??This is an important step forward for us, as it not only confirms that multiple retinal cells can be derived from human IPS cells. but also shows how similar the process is to normal human retinal development.
