For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

Scientists create a ‘mini-womb’ 3D model on a microfluidic chip which could lead to treatments for women affected by ...

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 - ...

A cell aggregation of human pluripotent stem cells and amniotic ectoderm cells generated by the published culture method and mimicking the gastrulation event in human embryos. Gray: nuclei, Cyan: ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo. "As you can see, all my lab is glass — ...
