Professor Henry T. "Hank" Greely comments on ABC 7 News (KGO) about a recent stem cell breakthrough reported by scientists in San Diego:

"For the first time they took cells from living human beings and managed to make five-day-old embryos that were genetically identical to those living human beings," says Prof. Hank Greely with Stanford Law School.

...

"I'm not sure I see any ethical problem there. The women aren't enticed to do this by money for research; the parents chances of having a baby aren't diminished," says Prof. Greely.

Professor Greely specializes in laws surrounding bioscience. He says stem cell research will remain controversial as long as human eggs and embryos are used.
