    Force-induced repolarization of an active crawler


    Recho, P, Putelat, T & Truskinovsky, L, 2019, ‘Force-induced repolarization of an active crawler’. New Journal of Physics, vol 21.


    We develop a quantitative model of mechanical repolarization in a contraction-driven gel layer mimicking a crawling cell. We show that the force-velocity relations for such active crawlers exhibit multi-valuedness and hysteresis under both force and velocity control. The model predicts steady oscillations of cells attached to an elastic environment and offers a self-consistent mechanical explanation for all experimentally observed outcomes of cell collision tests.
