| Outline of Final Research Achievements |
In this study, we developed an observatoin system that displays quantitatively and continuously the cultured cells continuously and non-invasively using focused ultrasound, and displays with acoustic impedance that is equivalent to elastic parameter. As the condition of the cytoskeleton highly reflects onto the elasticity of the cell, the degenerative process of the cytoskeleton of the cancer cell after being exposed to anticancer drugs, and the differentiation process of the myoblast calls were observed non-invasively and continuously in live condition. Together with the aim of application to regenerative medicine, we attempted to observe iPS cells.
