The cytoskeleton is a highly dynamic network, where structures are constantly built and destroyed. Cell migrati-on or cell division are prominent examples for this self organization and concomitant force generation. While until now, research focussed mainly on the mechanics of static structures, we concentrate on dynamic networks far from equilibrium. We reconstitute functional modules starting from a 3 component minimal model system and quantify the underlying processes. The experiments are accomplished by the development of computational tools to simulate the underlying processes. In the long run we want to increase the complexity of the system and design dynamic actin structures which mimic cytoskeletal reorganization and force exertion and finally to develop a minimal migratory system based on predictions obtained from simulations.
