Yet another major breakthrough has taken place in generating stem cells without killing an embryo. Scientists have found a way to take one cell from an embryo and multiply it into human stem cells. The procedure does not kill the embryo, and, in fact, embryos that have had this cell haircut have been successfully implanted and brought to term. This method seems especially promising because, unlike other non-lethal approaches discovered recently that require more research, it already works in creating new lines of stem cells!
