Many have been relying on a kind of moral escape hatch: the fact that every year there are tens of thousands of frozen embryos left over from fertility treatments in clinics around the country. National Institutes of Health guidelines say it is O.K. to do research on cells from such embryos, most of which would be destroyed anyway; but it is wrong to create an embryo solely for the purpose of harvesting...
...capture an embryonic stem cell, scientists must find an embryo, or blastocyst (from umbilical cord tissue, a frozen sample from a fertility clinic, an aborted fetus, or, most controversially, from a cloned specimen) ideally a few days after fertilization. Researchers then extract stem cells from the blastocyst, and, they hope, use those blank slates to create new, potentially curative, cells...
