| Outline of Final Research Achievements |
The main thrust of this study is to unravel the correlation between adhesion-induced tension and cytoskeleton dynamics out of equilibrium. Precisely functionalized planar lipid membranes (supported membranes) are used as a quantitative surrogate surface to modulate the coupling between cells and model surfaces. Unique experimental techniques developed in our lab are utilized to unravel the influence of adhesion-induced tension on the active ordering of cytoskeletons and the spatio-temporal patterns in cell migration. The experiments with cells undergoing different modes of deformation and migration, such as neural granule cells and cancerous epithelial cells, enable to gain general principles of non-equilibrium dynamics of cytoskeletons inside self-propelled, crawling cells.
