Lab-grown, virus-free stem cells repair retinal tissue in mice

Investigators at Johns Hopkins report they have developed human induced-pluripotent stem cells capable of repairing damaged retinal vascular tissue in mice. The stem cells, derived from human umbilical cord-blood and coaxed into an embryonic-like state, were grown without the conventional use of viruses, which can mutate genes and initiate cancers, according to the scientists.
