| Outline of Final Research Achievements |
We developed a mathematical model of elastic cytoskeleton. Based on this model, we identified the conditions that F-actins self-organize to bundle structure, mesh structure and network structure. We also developed a mathematical model of microtubule orientation in axon and dendrite, and then reproduced three distinct orientation patterns depending parameters. In addition, based on FERT imaging on migratory cells, we clarified how molecular signals are transmitted to morphological changes via cytoskeletal regulation. Moreover, we constructed a theory describing bi-directional attractive and repulsive turning response of the nerve growth cone.
