they cloned an embryo from the cell of a 30-year-old woman, scientists and

ethicists said cloning of humans, while controversial, is likely to be

"The question isn't whether they did it or not, but whether there is any

scientific reason to believe any top human fertility expert can't try and even

succeed in cloning a human," said Randall Prather, an animal embryo

researcher at the University of Missouri.

Dr. Prather and other scientists engaged in animal cloning experiments said

that breakthroughs in recent months in cloning mice and cattle, following the

cloning of a sheep in early 1997, suggest that duplicating such efforts in

humans is, if not possible now, likely to be possible soon. "The science is

there, or nearly there," said Dr. Prather who is attempting to clone pigs. He

noted that, if anything, humans, for technical reasons, "may turn out to

actually be easier to clone than some other animal species."

The Korean cloning announcement by fertility doctors Wednesday in Seoul

triggered a world-wide response of skepticism and alarm. Most countries,

including the U.S., have called for a moratorium on human clon

cloning of mice and cows reported in recent months "many of the cloned

people say it makes them feel queasy," Dr. Fost said. "These so-called

misinformation," Dr. Caplan said. "This isn't how scientists with integrity

But Dr. Wilmut destroyed that belief. This past summer, scientists in Hawaii

restricted. For example, scientists believed muscle cells could only make

embryos didn't advance to birth, probably because they were defective in

that much more work must be done in animals, especially primates, before

cells, adult cells have very specific functions that keep their activity
