Constriction Imposed by Basement Membrane Regulates Developmental Cell Migration

Investigators used the migration of the border cells (BCs) of the Drosophila egg chamber to unravel a new role of encasing BMs in cell migration. BCs moved between a group of cells, the nurse cells, that were enclosed by a monolayer of follicle cells, which was, in turn, surrounded by a BM, the follicl
