Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...

Resumen
Este resumen es generado por máquina.

La primera escisión del cigoto del ratón, no el punto de entrada del esperma, puede predecir la formación del eje del blastocisto. Este estudio de biología del desarrollo explora pruebas contradictorias sobre el prepatterning en embriones de mamíferos.
