| Outline of Final Research Achievements |
In this study, we constructed a versatile platform for a high throughput and massive single cell imaging, time-lapse analysis of intracellular receptor dynamics and selective collection of target cells based on technologies such as high-density single array technology, photo-induced cell release technology and site-specific fluorescent labeling method, and applied this platform to broad field of cell engineering. We developed a new photoactivatable PEG-lipid by combining photo-cleavable and non-cleavable PEG-lipids, and succeeded in the fabrication of ultra-high density single cell array, the simultaneous patterning of various type of cells and selective immobilization and collection of circulating tumor cells Furthermore, we developed monitoring and simulation technologies for intracellular dynamics of membrane receptor of non-adherent cells, which is induced by stimuli from outside of cells, and constructed a novel drug screening system based on these technologies.
