Phase field method to model single cell locomotion and collective cell interactions — •Sergio Alonso — Group of Computational Biology and Complex Sytems, Department of Physics, Universitat Politècnica de Catalunya, Barcelona, Spain

The interior of the living cells is complex and different types of processes happens simultaneously. Such dynamics are regulated by biochemical reactions and the dynamics of different biochemical components which are commonly modeled by reaction-diffusion equations. Polarization is typically described by Reaction-Diffusion processes and determines the head and the tail of the motion of the cell. Such process has to be connected with cell deformation and cell locomotion. The definition of a dynamical phase field to determinate the interior of the cell is a common tool for biophysical modelers. Here, I will review this technique and note some application in the case of crawling amoebae.
