Epiblast Cells During Gastrulation
The third week of development and the formation of the primitive streak sparks the beginning of gastrulation. Gastrulation is when the three germ cell layers develop as well as an organism’s body plan. During gastrulation, cells of the epiblast, a layer of the bilaminar blastocyst, migrate towards the primitive streak, enter it, and then move apart from it through a process called ingression.
