HONG KONG (Reuters) – Chinese researchers have managed to create powerful stem cells from mouse skin and used these to generate fertile live mouse pups.

They used induced pluripotent skin cells, or iPS cells — cells that have been reprogrammed to look and act like embryonic stem cells. Embryonic stem cells, taken from days-old embryos, have the power to morph into any cell type and, in mice, can be implanted into a mother’s womb to create living mouse pups.

Their experiment, published in Nature, means that it is theoretically possible to clone someone using ordinary connective tissue cells found on the person’s skin, but the experts were quick to distance themselves from such controversy.

“It has generated now more than 100 of second-generation (mice) and more than 100 third-generation (mice). It really demonstrates how fertile and strong the system is.”
