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 ...

In new research, scientists grew mouse embryos to half term in an artificial womb. The milestone is equivalent to a human embryo at five weeks development. Early pregnancy and implantation are very ...

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 ...

Biologists have long held that a fetus needs a living uterus to develop. Maybe not anymore. By Gina Kolata The mouse embryos looked perfectly normal. All their organs were developing as expected, ...
