3D cell motion on a sagittal section of a mid-gastrulation Xenopus laevis embryo. Red arrows designate maximum cell speed (~4 µm min^–1): mesendodermal leading-edge runners (top center); endodermal wall of inflating archenteron (left); blastopore (bottom center). Note pronounced vegetal rotation on lower right and epibolic movement throughout the periphery.
