Researchers 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 weeks after fertilization. This is ...

All embryos of a single pod usually wriggle out one after another within several minutes. Once out, they immediately shed an embryonic membrane called the serosa. An individual hatchling, lying on its ...

Mesoderm arises at gastrulation and contributes to both the mouse embryo proper and its extra‐embryonic membranes. Two‐photon live imaging of embryos bearing a keratin reporter allowed recording ...

The APs were described as embryonic based on the relatively depolarized resting membrane potential and slow AP upstroke. Repeated impalements of an individual beating outgrowth revealed a reproducible ...

It's not hard to deduce where it came from." Gauna argues that the milky film he captured coming off the animal is embryonic membrane from birth and says the shape of its dorsal fin doesn't match ...

Sternes believes the material was a residual embryonic membrane composed of a nutrient-rich "milk" that the mother secreted in the uterus before the pup was live-born. Although it is possible that ...

Illustration: Rikke Linssen During the initial days after fertilization, the nutrient layer surrounding the embryo is not fully developed, allowing for more space. The membrane may play a crucial role ...

These naive cells are then made to form cells of the embryo, placenta, yolk sac and "extraembryonic mesoderm membrane" — the precursor to the chorionic sac, the outermost membrane that surrounds ...
