Cadherin-Mediated Cell Coupling Coordinates Chemokine Sensing across Collectively Migrating Cells.

The directed migration of cells sculpts the embryo, contributes to homeostasis in the adult, and, when dysregulated, underlies many diseases [1, 2]. During these processes, cells move singly or as a collective. In both cases, they follow guidance cues, which direct them to their destination [3-6].
