Many of the cell and tissue movements in Xenopus
gastrulation happen simultaneously. Still identify the different types of
behaviors that occur during Xenopus gastrulation:
A. Epiboly: The thinning
and spreading of the animal cap cells over the vegetal hemisphere, powered by
proliferation and radial intercalation.
B. Vegetal rotation:
Vegetal cells asymmetrically press up against the inner blastocoel roof on the
dorsal side.
C. Bottle cell formation
and invagination: The leading edge of invaginating cells crawls up onto the
blastocoel roof.
D. Involution and cell
migration: Localized apical constriction at the dorsal blastopore lip creates
anisotropic forces that foster invagination.
E. Convergence and
extension: The targeted medial-to-lateral intercalation of cells on the midline
(convergence) drives anterior-posterior axis elongation (extension).

In cloning experiments on the frog xenopus laevis, nuclei were removed from intestinal cells of tadpoles and transplanted into zygotes whose nuclei had been removed. A small percent of these zygotes developed into normal frogs, suggesting that
