This project models collective cell migration and differentiation as part of a wound healing process. The hybrid mathematical model used in this project consists of an agent-based model for the cells combined with a system of coupled partial differential equations for two forms of the growth factor molecule TGF-beta. The model is implemented in Morpheus, a software package designed for the simulation and integration of cell-based models with PDEs. We determine some conditions in which the additional release of TGF-beta by myofibroblasts is conducive to the migration and differentiation of fibroblasts.
