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 ...

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

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.

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

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

According to multiple studies, one in three pregnancies results in miscarriage, and one in 33 babies that are born will have a birth defect, due to the embryo forming incorrectly in the womb. Studying ...

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 ...

Embryonic morphological development is delayed in live pregnancies ending in miscarriage, according to a prospective cohort study from the Netherlands. Among over 600 singleton pregnancies, those ...
