| Outline of Final Research Achievements |
In this study, we explored the function of intracellular calcium ions in epithelial morphogenesis by using the neural tube closure of the African clawed frog as a model. As a result, we developed the technique that induces one of the cellular movements necessary for epithelial sheet deformation, called apical constriction, and revealed the molecular mechanism of it. Moreover, we proposed the mechanical basis by which the synchrony of the apical constriction affects the efficiency of tissue deformation. The results of this study are expected to contribute to the understanding of the principle of morphogenesis of various epithelial organs as well as the neural tube.
