We have been exploring molecular mechanisms of pattern formation of vertebrate embryos, with central nervous system, limb bud and heart as model organs, and with several key transcription factors as our keen interest. Nonetheless, we have noticed that extensive analyses on the genetic programs are not sufficient for understanding thoroughly the dynamic pattern formation of developing embryos. Recently, we have identified that several proteins change their shapes and conformation in response to physical forces that are generated by cells, hereby such strains trigger next biochemical responses. We are now studying this novel mechanism to understand functional roles of physical forces generated by cells and sensed by cells.
