The impact of contact inhibition on collective cell migration and proliferation (2108.04743v1)

Published 10 Aug 2021 in cond-mat.soft

Abstract: Contact inhibition limits migration and proliferation of cells in cell colonies. We consider a multiphase field model to investigate the growth dynamics of a cell colony, composed of proliferating cells. The model takes into account the mechanisms of contact inhibition of locomotion and proliferation by local mechanical interactions. We compare non-migrating and migrating cells, in order to provide a quantitative characterization of the dynamics and analyse the velocity of the colony boundary for both cases. Additionally, we measure single cell velocities, number of neighbour distributions, as well as the influence of stress and age on positions of the cells and with respect to each other. We further compare the findings with experimental data for Madin-Darby canine kidney cells
