Embryos have been produced from skin cells, according to researchers in California. In a report that could lead to the advancement of stem cell research, the embryos that were produced were clones of the two men who supplied the skin cells.

Is this science fiction? No -- reality. Although stem cell development with the use of cloned embryos has been done before, the duplication of results can be seen as a measure of success. In this case, would you be in support of stem cell lines grown from "cloned" embryos -- not "real" embryos?

The philosophical versus medical discussion can start anew here, even though Dr. George Daley indicated that the real next breakthrough would come when stem cell lines are created from cloned human embryos. Others stated that it was only "a matter of time" before that happened.
