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 ...

The process of a single-celled zygote developing into a complex multicellular organism is precisely regulated at spatial and temporal levels in vivo. However, understanding the mechanisms underlying ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

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 ...

In primates, abnormalities during gastrulation and early organogenesis lead to a high incidence of early abortion and developmental defects at birth 8. Thus, elucidating the cellular and molecular ...

Scientists in the Brivanlou lab used light-inducible gene expression (yellow circle) and embryo models to demonstrate that, at the start of gastrulation, body-axis formation requires an interplay ...

Egg whites may be perfect for a health-conscious breakfast, but egg yolks turned out to be the key ingredient for cultivating bird embryonic stem cells (ESCs) in the lab. Using a growing medium of egg ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

Humans have around 30 trillion cells in our adult bodies. Amazingly, each of these cells came from a handful of about 100 stem cells in the earliest days of development. The ability of these embryonic ...
