Increased cellular velocity and cell shape elongation are characteristics of the unjammed layer. (a) Representative speed maps show the differences in cellular velocities between jammed and unjammed layers. The cellular velocity is increased in the unjammed layer, which is induced by mechanical compression. (b) The theory developed by the vertex model predicted cell shape changes during the phase transition between the jammed and unjammed layers. Predicted cell shape is cobblestone-like in the jammed layer, while it is elongated in the unjammed layer. Figure from [40] with the permission from the publisher.
