Title: Re: Explain gastrulation and summarize the germ layers produced during this process. Post by: eggslily on Dec 8, 2016 Gastrulation is the rearrangement and migration of the cells of the bilaminar embryonic disc to form the trilaminar embryonic disc. This is the stage at which the three germ layers develop. The first cells that migrate in this way become the inner germ layer, or endoderm, which replaces the hypoblast. The next cells that migrate to a position between the epiblast and endoderm, and this becomes the middle layer, the mesoderm. The remaining cells of the epiblast form the outer layer, the ectoderm.
