Tiny, a mouse created from powerful stem cells created from mouse skin, looks around on a sofa in China in this January 2009 photograph made available July 24, 2009. Chinese researchers have managed to create powerful stem cells from mouse skin and used these to generate fertile live mouse pups. Led by Qi Zhou at the Chinese Academy of Sciences's State Key Laboratory of Reproductive Biology, the team created pluripotent skin cells, or iPS cells, using mouse fibroblasts, which are cells found in connective tissue in the skin. Pluripotent skin cells are cells that have been reprogrammed to look and act like embryonic stem cells. Reuters Pictures 4 months ago
