Atomic Force Microscopy to Study Mechanics of Living Mitotic Mammalian Cells

概要

While biochemical pathways within mitotic cells have been intensively studied, the mechanics of dividing cells is only poorly understood. In our recent report, an experimental system combining fluorescence and atomic force microscopy was set up to study dynamics of mitotic rounding of mammalian cells. We show that cells have a rounding pressure that increases upon mitotic entry. Using specific inhibitors or perturbations, we revealed biological processes required for force generation that underpin the cell rounding shape change during mitosis. The significance of the finding and an outlook are discussed.
