Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Analyzing embryo movements in uteruslike environments could offer clues to improving the success rate of in vitro ...

By tracking the fate of individual embryonic stem cells, researchers have found that endoderm cells—early embryonic cells ...

Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the woman’s uterus. Part of the problem is that researchers have no idea how ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Scientists recorded in 3D and in real time the exact moment a human embryo implanted itself in an artificial uterus, opening new avenues for treating infertility.

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...

The biological and legal definitions of “embryo” don’t match, and that will become a problem, according to Nicolas Rivron, PhD, of the Institute of Molecular Biotechnology of the Austrian Academy of ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

A research team has unveiled a non-destructive, highly accurate approach for determining the optimal timing of embryo rescue ...
