| Outline of Final Research Achievements |
The aim of this project is to model collective behavior of cell moving on a substrate. As a method, we used non-biological experimental model as well as mathematical model. We found that shape of excluding volume, competition between conservative and non-conservative force, transition of particle condition, can be relevant components affecting on collective motion in an experimentally tractable manner.
Our experimental as well as mathematical model showed that the collective motion of elements that is coupled though diffusion field will be an interesting class, in which competition between conservative and non-conservative force appears. Our experimental model system developed in this project, droplet and particle moving on a water surface, and polystyrene particle moving under alternating electric field, will be candidates for models to reproduce collective behavior of cells interacting though diffusion field.
