Multiscale order, flocking and phenotypic hysteresis in the cellular Potts model of epithelia

Calvin C. Bakker, Fran\c{c}ois Graner, Luca Giomi, Marc Durand

In the cellular Potts model of epithelia, increasing actin polymerization rate drives a transition to long-range flocking with multiscale orientational order and phenotypic hysteresis.

Claims

C1strongest claim

We uncover a remarkably rich phase diagram featuring multiple types of orientational order, either as distinct phases or coexisting across length scales. We identify a specific pathway in parameter space along which a gradual increase in the actin polymerization rate drives a phase transition into a long-range flocking state.

C2weakest assumption

That the specific implementation of cytoskeletal activity and cell morphology in the cellular Potts model sufficiently captures the essential physics of real epithelial cell monolayers to produce the observed orders and hysteresis.

C3one line summary

Cellular Potts model simulations uncover multiscale orientational order, actin-driven flocking transitions, and phenotypic hysteresis in epithelial monolayers.
