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 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 ...

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 have advanced human-animal chimera research by successfully growing human cells within the organs of mice. This development could bring experts closer to the goal of custom-growing human ...

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 ...
