A human embryo at roughly three to four weeks of development. The Tiangong experiment uses stem cell-derived embryo models at ...

The embryos cannot develop into humans, and are being used to study development in outer space.

China launched embryo-like structures made from living human stem cells to its Tiangong space station for a first-of-its-kind ...

A clutch of artificial human embryos on China’s Tiangong space station could help researchers better understand whether human ...

China's Tianzhou-10 mission just delivered embryo-like structures made from living stem cells to the Tiangong space station. Experiments could shed light on how radiation and microgravity affect human ...

Microgravity and higher radiation levels in orbit could disrupt cell alignment, gene expression, or organ formation.

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

A 190-million-year-old dinosaur embryo is the oldest recorded one to date, say scientists who hope the find helps them understand the development of a long-necked plant eater. Researchers in Canada, ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...
