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 ...

Caltech researchers have developed a powerful new method for creating embryo-like structures from stem cells that could ...

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

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 ...

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 ...

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

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 ...

A powerful new method for creating embryo-like structures from stem cells that could transform how we study fertility.
