Outline of Final Research Achievements

This study aims to reveal mechanical states of multicellular system in three-dimensional organogenesis using computational simulations of the reversible network reconnection (RNR) model. Because the displacement velocity of the whole tissue is assumed to be small in the RNR model, the applicability of the model is limited to small deformations. Therefore, to apply the RNR model to simulating dynamic organogenesis, we improved the RNR model by taking account of the effects of local velocity on deformations. Moreover, by simulating the process of epithelial growth within viscous liquid using the proposed model, we analyzed the effects of extracellular viscosity on epithelial morphogenesis.
