WASHINGTON (Reuters) - One gene directs both embryonic and adult stem cells to perform the self-renewal function that is crucial in their potential broad use in medical treatments, researchers said on Thursday. While the biology of these types of stem cells is very different, a study published in the journal Cell showed that they share at least this one key feature -- a gene called Zfx that controls their ability to self-renew.
