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 ...

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 ...

Here’s what a pregnancy looks like inside a microfluidic chip. At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining of the ...

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 ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...
