The formation of an integrated tissue from individual cells depends on the properties of the individual cells as well as the interaction of many cells acting as a collective. Three fundamental physiological processes govern the collective scaling from the individual cell to a working tissue: cell sorting, tissue assembly, and collective cellular migration. Mechanistically, cell sorting is governed by differential adhesion, whereas tissue assembly is controlled by the epithelial-tomesenchymal transition and its inverse, the mesenchymal-toepithelial transition. The mechanism driving collective cellular migration, however, is not clear. To fill that gap, here we consider cell jamming and unjamming, and their role in collective cellular migration.
