The creation of a woolly-mouse embryo marks a significant leap in the field of de-extinction, bringing us one step closer to reviving the iconic woolly mammoth. By combining advanced gene-editing ...

Researchers announce the development of a mouse embryo model, complete with beating hearts and the foundations for a brain and other organs, out of mouse embryonic stem cells. Just two weeks after ...

When a sperm meets an egg, a lot has to go right for an embryo to develop into a complete organism. One critical step of ...

A six-legged mouse embryo, with extra limbs in place of genitals, has been engineered by scientists. It sounds like sci-fi, we know – but the curious creature, which also has several of its internal ...

Scientists funded in part by the National Institutes of Health have generated a mouse embryo model, or embryoid, that develops beyond neurulation—formation of the neural tube, which gives rise to the ...

As people age, so do all of our cells, which accumulate damage over time. But why our offspring don’t inherit those changes — effectively aging a child even before birth — has been a mystery. “When ...
