Research Abstract

Mechanisms of unique cell movement of isolated gastrula cells and roles of this movement in morphogenetic cell movement during gastrulation were studied in amphibian gastrulae. Cell biological study revealed that intracellular Ca2+ concentration changes and actin polymerization play in the unique cell movement of isolated gastrula cells and morphogenetic cell movement of intact gastrula. The present study suggested that development and formation of the Ca2+ signaling mechanisms in embryonic cells during gastrulation play an important role in the initiation and execution of morphogenetic cell movement during gastrulation.
