Researchers have produced two monkeys with a procedure similar to that used to clone a sheep in Scotland, a development expected to help research into AIDS, alcoholism, depression and other illnesses.

Gleaning stem cells from cloned monkey embryos, as a team of Oregon researchers has done, is an impressive step. But it probably won't lead to medical treatments anytime soon. One hurdle is ethical ...

NEW YORK -- Scientists in Oregon say they've reached the long-sought goal of cloning monkey embryos and extracting stem cells from them, a potentially major step toward doing the same thing in people.

Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos. In June, ...

Not too shabby, humans. New research shows that certain primate stem cells have pluripotency superior to some types derived from mice. The study, published in Nature, maps how pluripotency differs ...
