Advances in Modelling of Epithelial to Mesenchymal Transition
This paper presents simulations of in vitro Epithelial to Mesenchymal Transition (EMT). The conditions of 2D migration on the surface, and 3D invasion into a collagen gel are represented as a cellular Potts model. The model demonstrates that a loss of endocardial adhesion is a sufficient condition for 2D migration behaviour, while a simultaneous loss of endocardial cohesion and gain in endocardial to collagen gel adhesion is a sufficient condition for 3D invasion. The 3D model captures the hierarchy effective surface tensions that correspond to the three experimental conditions of stable monolayer, 2D migration, and 3D invasion. A 2D cellular Potts model is used to investigate the relationship between cell shape changes, motility and adhesion during the condition of 2D migration.
