Before the process of gastrulation, the embryo continuous to form an epithelial sheet of cells. The primitive streak is the visible. Specifically, they establish all brain regions, a neural tube, a beating heart and a gut tube. As the embryo undergoes all of these changes, its cells continuously undergo mitosis, allowing the embryo to grow in size, as well as complexity33. This process provides the basic embryonic architecture, an inner layer separated from an outer layer, from which all animal forms arise. In chick, the formation of the internal layers requires the generation of a macroscopic convection-like flow, which involves up to 50,000 epithelial cells in the epiblast. This process is called gastrulation. In embryology, gastrulation is a process in which an embryo transforms from a bilaminar germinal disc (hypoblast and epiblast) to a trilaminar germinal disc (endoderm, mesoderm and ectoderm) during early development.
