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 ...

Advances in genetic and computational tools have enabled researchers to study complex networks of gene expression in individual cells, and the patterns of gene expression in a population of cells ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

How do cells turn into organs? During embryonic development, three germ layers form, known as the endoderm, the mesoderm, and the ectoderm. These germ layers give rise to different parts of the ...

A mature cell of one type can be turned into a mature cell of another type without the cell having to pass through an earlier stage of development. This is called direct reprogramming, a reliable but ...
