Don't order the birth announcements yet. Top experts are saying that despite impressions to the contrary, the human embryos created by a Korean team are not a great—or terrifying—leap toward a cloned baby.

Make no mistake: the Korean scientists have no intention of attempting such an act. During a mid-February press conference announcing their achievement, they implored every country to follow Korea's example and outlaw human reproductive cloning. Instead, they seek to explore the medical potential of stem cells—which they managed to glean from one cloned embryo.

Korean researchers transferred the nucleus of a nonreproductive cell containing a woman's genes into a nucleus-free egg from the same donor. After a jolt of electricity, the reconfigured egg begins to divide. A human stem cell line was derived from one such embryo. (Photo credit: AAAS/Science)

Some day, researchers may grow stem cells into immunogenetically-matched replacement tissues to treat . . . [Full Text of this Article]
