Collective Cell Movement under Cell-Scale Tension Gradient at Tissue Interface

In this paper, we examine the emergence of cell flow induced by a tension gradient on tissue interface as in case Marangoni liquid interface. We consider molecule density polarity heterophilic adhesion between tissues origin gradient. By applying cellular Potts model, demonstrate that polarization concentration (i.e., intracellular localization) molecules can induce similar to flow. contrast ordinary flow, is oriented opposite direction The optimal range strength also identified for existence
