Progenitor cells that will contribute to formation of specific heart tissues are derived from distinct regions of the ...

The authors therefore propose that, compared to anamniotes, the chick (and possibly all amniotes) evolved an additional intercalation event that occurs in the ectoderm and precedes gastrulation.

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 ...

To answer this, Prakash and three other collaborators studied chick development using fluorescent ... to better understand human and mouse gastrulation in the future and the emergence of birth ...
