Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

BEIJING -- Chinese scientists reconstructed a 3D model of a human embryo within two to three weeks after fertilization, which opens a new door into very early human embryonic development. Out of ...

A recent study in Advanced Science presents a method for studying early human embryology by bioprinting epiblast-like structures from human-induced pluripotent stem cells (hiPSCs). The model forms a ...

The new platform's ethically grounded approach promises to reveal much about how human embryos form during the earliest stages of pregnancy. It's one of life's most defining moments -- that crucial ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow ...

At some point in our evolution, we lost the ability to activate a reproductive mechanism called embryonic diapause, which slows development, usually during the blastocyst stage. And so, unlike mammals ...

Only about one out of three conceptions leads to birth. 1 Approximately a third of embryos fail to attach to the uterus, while another third is lost after the embryo implants. “Human reproduction is ...
