| Outline of Final Research Achievements |
In this study, we use microfabrication technology and folding technology of origami engineering to create microplates that serve as scaffolds for cells, and by folding the cells after culturing them, the shape changes due to the folding of the cells during the process of morphogenesis. We aimed to elucidate the relationship between mechanical stimulation and the mechanism of morphogenesis in vivo. During the research period, we produced a magnetic microplate, cells were cultured on the plate, and then the microplate was folded and unfolded using a magnetic field under a microscope, and the shape of the cells was successfully controlled three-dimensionally. By using a magnetic material, it can be driven in a non-contact manner, so it is possible to change the shape of cells without the need for wiring.
