South Korean researchers say they've successfully cloned a human embryo

Washington-AP -- Researchers in South Korea claim to have been the first to successfully clone a human embryo -- and then harvest the master stem cells that could someday be used to cure diseases.

Scientists from Seoul National University credit their success to extremely fresh donor eggs and very gentle handling.

The development is expected to trigger new international debate over banning human cloning. While the Bush administration wants a total embargo, others support this type of "therapeutic cloning" -- that might eventually let patients grow their own replacement tissue.

Some doctors think it's the key to creating customized cures for diabetes, Parkinson's and other diseases.

The research will be presented today at a meeting of the American Association for the Advancement of Science.
