CHICAGO — The American Medical Association (search) endorsed cloning (search) for research purposes Tuesday, saying the procedure is medically ethical but allowing doctors who oppose the practice to refuse to perform it.
"It makes a stance for science," said Dr. Michael Goldrich, incoming chairman of the committee that drafted the cloning report.
The proposal focuses on a procedure designed to create embryos to cultivate their stem cells, which are master cells that can potentially grow into any type of human tissue. Scientists believe such cells could potentially be used to treat a wide range of human diseases.
Such early embryos would be discarded when they consist of only a few cells, but they could theoretically develop into a human if implanted into a woman's uterus.
The proposal received wide support from doctors and medical groups including the American Society for Reproductive Medicine (search). But some adamantly opposed it with arguments reminiscent of the nationwide abortion debate.
Calling embryo cloning for research purposes medically ethical is "totally inappropriate ... when a number of us believe that human beings start with two cells," said Dr. John McMahon of Helena, Mont.
The proposal echoed recommendations from a National Academy of Sciences panel last year, which advocated a government ban on cloning to produce humans but said cloning for research should be allowed.
The U.S. House earlier this year passed a Bush administration-backed measure that would ban both types of cloning. The measure hasn't been acted on in the Senate.
The AMA's Council on Ethical and Judicial Affairs submitted the proposal with hopes that it would become official AMA policy. Policymaking delegates adopted the measure without debate after discussing the issue Sunday.
