China has delivered the world's first human artificial embryo models to orbit to test how microgravity affects human ...

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

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

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 ...

Chinese researchers have mapped the world's first complete spatiotemporal gene expression atlas of human embryos during the ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

The current practice of freezing embryos—used to assist reproduction in humans or animals or to conserve endangered species—routinely causes ice to form within the cells, ripping through cell ...

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 ...
