Description Correlated velocity patterns and associated large length-scale transmission of traction forces have been observed in collective live cell migration as a response to a "wound". We argue that a simple physical model of a force-driven heterogeneous elastic membrane sliding over a viscous substrate can qualitatively explain a few experimentally observed facts: i) the growth of velocity ordering which spreads from the wound boundary to the interior; ii) the exponential tails of the traction force distributions; and iii) the swirling pattern of velocities in the interior of the tissue.
