The molecular and cellular mechanisms that keep cells apart at compartment boundaries remain unclear. In early Drosophila embryos, cells transiently invade neighbouring compartments, but an actomyosin-based barrier formed of cable-like structures pushes them back into their compartment of origin, in mitotically active epidermis.
