Millions of neurons branch throughout our bodies, keeping them in close communication with our brains. This peripheral network begins to take shape long before birth, as the cells of a growing embryo ...

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

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 - ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

Their findings, recently reported in the journal Nature, overturn longstanding assumptions in developmental biology and could change the way scientists think about treatments for a variety of ...
