For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

By examining genetic clues that linger in adult cells, scientists have now gained surprising insights into the developmental ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

Images and videos of embryo modelsFor the first time, stem cells typically considered restricted to forming body tissues spontaneously formed a ...

Their findings, recently reported in the journal Nature, overturn longstanding assumptions in developmental biology and could ...
