For the first time, scientists have created embryos that are a mix of human and monkey cells. The embryos, described Thursday in the journal Cell, were created in part to try to find new ways to ...

Scientists injected human stem cells into macaque embryos into a study on human development. Some of the embryos continued to develop for 20 days, researchers said. But the experiment has sparked an ...

Scientists based in China have created a monkey chimera with two sets of DNA, experimental work they say could ultimately benefit medical research and the conservation of endangered species. The ...

The images are unsettling, to put it mildly: a baby monkey whose skin grows eerily green, with glowing fingertips reminiscent of E.T. This is “#10,” the world’s first live-born monkey that’s largely ...

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, ...

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 ...
