On the contrary, he left open the possibility of funding studies using embryos created specifically so their cells can be harvested -- which Congress has barred, but which some advocates would like to allow. The president took no position on whether scientists should be permitted to create embryos for the sole purpose of dismembering them for their stem cells.
He did, however, reject another option. "We will ensure," he said, "that our government never opens the door to the use of cloning for human reproduction. It is dangerous, profoundly wrong and has no place in our society, or any society."
Is that a scientific judgment? No, it's a philosophical one, reflecting Obama's moral values. Apparently, the folks in the white lab coats can't be relied on to answer all questions.
But this position is hard to square with his professed approach. On one hand, the president says his policy is "about letting scientists like those here today do their jobs, free from manipulation or coercion." On the other, he will use coercion to keep them from doing reproductive cloning.
What this mandate means is simple: It may be permissible for scientists to create cloned embryos and kill them. It's not permissible to create cloned embryos and let them live. Their cells may be used for our benefit, but not for their own.
There lies the reality of embryonic stem cell research: It turns incipient human beings into commodities to be exploited for the sake of people who are safely past that defenseless stage of their lives.
It's a change that poses risks not just to days-old human embryos. The rest of us may one day reap important medical benefits from this research. But we may lose something even more vital.
