Unjamming transition is induced by ionizing radiation. (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 ionizing radiation. Scale bar, 100 μm. (b) Phalloidin staining from the corresponding cells above show the differences in cell shape between jammed and unjammed layers. HBE cells maintain a cobblestone-like shape in the jammed layer, whereas become elongated shape in the unjammed layer. Figure from [59] with the permission from the publisher.
