In this image of mouse embryonic fibroblasts undergoing reprogramming, each colored dot represents messenger RNA associated with a specific gene that is active in cells being reprogrammed. Red dots represent... Several years ago, biologists discovered that regular body cells can be reprogrammed into pluripotent stem cells — cells with the ability to become any other type of cell. Such cells hold great promise for treating many human diseases.
