Overview of Research and Education
Research Contents: We are interested in the behaviors of cells and tissues, especially collective cell migration, 3D morphogenesis, and tissue construction. To understand these phenomena, we utilize soft biomaterials (e.g. collagen gels, Matrigels) for cell culture to mimic biological environments and analyze the behaviors with approaches of both molecular biology and mechanobiology. Furthermore, we are using extracellular matrices of different stiffness and investigating the mechanism of cancer progression induced by substrate stiffening. We are able to contribute to improve regenerative medicine and cancer therapy with our research approaches.
