In 2021, scientists grew human stem cells in a monkey embryo, creating a human-ape hybrid. Is this mad science? Is it immoral ...

Scientists have successfully used human stem cells to patch a hole in a monkey’s retina, restoring the primate’s vision and marking a successful step forward in the quest to treat age-related vision ...

NEW YORK -- For the first time, researchers have used the cloning technique that produced Dolly the sheep to create healthy monkeys, bringing science an important step closer to being able to do the ...

Chinese scientists clone monkeys using the same technique that produced Dolly the sheep two decades ago, breaking a technical barrier that could open the door to copying humans.

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.

Transplanted human stem cells successfully repaired macular holes in monkey models of the disorder. This is according to a new study from researchers at the Center for Biosystems Dynamics Research at ...

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 ...
