Gastrulation is a process common to nearly all metazoan organisms during which an embryo with distinct tissue layers develops out of a seemingly unstructured assembly of cells referred to as 'blastula ...

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 ...

Gastrulation is the formation of the three principal germ layers - endoderm, mesoderm and ectoderm. Understanding the formation of the basic body plan is not only important to reveal how the ...

Insights into the origin of bilaterian characteristics will be obtained by investigating the four basal bilaterian taxa: Cnidaria, Ctenophora, sponges and the placozoan Trichoplax adhaerens.

Gastrulation is the process that creates the 3 axes of the body. While this stage was thought to be driven solely by chemical signals, new tools made it possible to test whether physical forces play ...

It’s one of life’s most defining moments—that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage for ...

Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement ...

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...
