Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can provide ...

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 - ...

Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

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 ...

The human brain's remarkably prolonged development is unique among mammals and is thought to contribute to our advanced learning abilities. Disruptions in this process may explain certain ...

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 ...

A new study led by scientists from the Hebrew University of Jerusalem and INSERM identified genes essential for turning embryonic stem cells into brain cells, including a gene linked to a previously ...
