Researchers at Tongji University have identified arachidonic acid (ARA) metabolism as a critical regulator of early human embryo implantation. Using a novel in vitro co-culture system of human ...

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 ...

The work appears in Cell. "Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said ...

Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists. By Carl Zimmer Scientists at Columbia University have ...
