Suppression of Pcdh8/paraxial protocadherin is required for efficient neighbor exchange in morphogenetic cell movement during zebrafish notochord formation.

In certain forms of collective cell migration, changes in neighboring cells (neighbor exchange, NE) are essential. In the axial mesoderm in zebrafish, for example, the notochord is established through cell movements known as convergence and extension (C&E), which involves NE. For NE to occur efficiently, the balance between cell-scale and supracellular stresses plays a crucial role, but the molecular basis of how these stresses are controlled remains unclear.
