Many pregnancies face challenges before a woman even knows she is expecting. One reason is the embryo’s rapid growth; any disruption during this stage can affect development. During week 3, the embryo ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

In July, researchers in the United Kingdom published a code of practice on how human stem cells should be used to mimic embryo development in the laboratory. This code was produced by a working ...

Their “programmable” embryo-like structures, also known as embryoids, can be used to study the role of certain genes in early development The earliest days after fertilization, once a sperm cell meets ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

A molecular tracking technology called DNA Typewriter can record the cellular lineage of a mouse embryo, from a single cell to over a million.
