Our research group aims to clarify the mechanisms by which cells sense mechanical stimuli and regulate their activities in tissue adaptation, regeneration and stem cell differentiation in morphogenesis. To better understand the mechano-regulation of these dynamical processes through the complex hierarchical structure-function relationships, bridging spatial and temporal scales from microscopic molecular/cellular activities to macroscopic tissue behaviors is very important. Based on multiscale biomechanics, our group is involved in the integrated biomechanics and mechanobiology researches of modeling and simulation combined with experiments, focusing on mechano-biochemical couplings in the system dynamics.
Research and EducationLiving systems have the ability to functionally adapt to the changing mechanical environment by remodeling their structures dynamically at the organ, tissue, cellular and molecular levels. The mechanical environment also has an enormous influence on the dynamic rearrangement of the multicellular system during morphogenesis in tissue development as well as the remodeling of intracellular structures during cell division and cell migration. To address these interdisciplinary issues from mechanical viewpoints, we are conducting biomechanics research aiming to mechanically understand structural and functional dynamics at the molecular, cellular, and tissue levels, as well as mechanobiology research aiming to elucidate these biological functions, particularly research integrating in vitro experiments, mathematical modeling and computer simulation based on mechanics. Furthermore, our goal is to create new materials and structures for regenerative medicine by integrating self-organized structures appearing in a bottom-up manner in bio-molecular systems, with nano- and micro-technologies which control their structures by a top-down engineering approach.
