University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...

In a scientific “first,” a tiny heart structure composed of human cells has been successfully grown within a pig embryo. Interestingly, this heart kept beating on its own for an impressive 21 days.

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Researchers at UCL and the Francis Crick Institute have, for the first time, identified the origin of cardiac cells using 3D images of a heart forming in real-time, inside a living mouse embryo. For ...

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 ...
