Researchers have developed the first-ever embryo-like model from human embryonic stem cells, a workaround that will let them examine birth defects and diseases they couldn’t otherwise, given ethical ...

Technological, ethical and legal issues have limited the understanding of the early stages of embryonic development in humans, despite its importance in basic developmental biology and reproductive ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Why do pregnancies last longer in some species than others? Researchers at the Francis Crick Institute have found the clock that sets the speed of embryonic development and discovered the mechanism is ...
