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 ...

For decades, scientists have been able to look at individual moments in the development of an embryo: a snapshot of a ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

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 ...

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