Research Interests
Cell migration:
Cell migration plays critical roles in various physiological and pathological processes. He took advantage of photoactivatable cell culture substrates to confine cells within a given geometry and induce their migration by controlled photo-irradiation of the substrate. For example, he demonstrated collective characteristics of cells became enhanced by increasing cluster size and culture time. This approach is useful not only for the systematic understanding of cell migration, but also for engineering migration characteristics for tissue engineering applications.
Dynamic cell micropatterning on a photoactivatable cell culture substrate:
Cell micropatterning is useful for tissue engineering, fundamental cellular studies, and cell alignment on sensing devices. He developed a glass coverslip modified with a silane-coupling agent having a photocleavable group, and applied it to dynamic cell micropatterning. In contrast to conventional methods, dynamic cell micropatterning allows one to in situ alteration of cell micropattern during cultivation. Based on this feature, he succeeded in guidance of protrusions from single cells and co-culturing of heterotypic single cells.
Fluorescence imaging of protein conformational change in living cells:
Proteins involved in intracellular signaling dynamically change their conformation upon activation. He synthesized fluorescent molecules that can be selectively attached to a peptide sequence in living cells. By genetically engineering a protein of interest to have the peptide sequence and labeled it with the fluorescent molecule, he developed a method for real-time imaging of protein conformational change in living cells. Based on this method, he succeeded in visualizing agonist-induced conformational dynamics of a cytosolic protein (calmodulin) and a membrane protein (β2 adrenergic receptor) in living cells.
