...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...
...draw it right where it is and hold it. It is a reasonable moral calculus to use and thus derive some good from an already doomed, fertility clinic blastocyst. Moreover, federal funding would for the first time permit the procedure to be regulated...
...Stem-cell production permitted only from otherwise discarded fertility-clinic embryos or from fetal cadavers...
...FERTILITY CLINICS During in-vitro fertilization, clinics routinely fuse more than one egg with sperm. That way, if implanting a fertilized egg doesn't work the first time, they can try again. This practice has left thousands of unwanted embryos stored in clinic freezers. James Thomson, left, the first scientist to establish a human stem-cell line, used such embryos...
...ABORTED FETUSES John Gearhart, above right, the Johns Hopkins biologist credited, along with Thomson, with first culturing stem cells, extracted his from fetuses donated by women at a nearby abortion clinic...
