Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications ...

Using staged embryos, researchers report a genomic analysis of mouse gastrulation and organogenesis. The post-implantation period is a dramatic one for the mouse embryo. Over the course of about 3 ...

Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a 'black box' of human development. This is because human embryos are ...

In a recent study published in the Cell journal, researchers showed that post-gastrulation synthetic embryos (sEmbryos) could be synthesized outside the uterus using mouse naïve embryonic stem cells ...
