Gastrulación. Introducción. ▫ Es la etapa más compleja de la 3a. Semana. ▫ Ocurre en todas las especies. ▫ Formación de las tres hojas germinativas y. La gastrulación es el proceso mediante el cual se forma, a partir de la migración de poblaciones celulares ubicadas en el epiblasto, un embrión trilaminar. Gastrulación ⇒ Las células del mesodermo proliferan hacia la membrana bucofaríngea, un poco más hacia arriba, sobre la cabeza.
