Reprogrammed mouse skin cells yield mice that can breed
Chinese scientists have created 27 healthy mice from reprogrammed cells known as induced pluripotent stem (iPS) cells. The iPS cells were reprogrammed from adult mouse skin cells by modifying four key genes using retroviruses, turning them into an embryo-like state. iPS cells are a hot research topic at present as they offer the prospect of a limitless supply of an individual's own stem cells if the technique is replicated in humans, potentially avoiding the pitfal...
