Cell divisions are necessary, but also very disruptive for morphogenesis. Dividing cells lose many intercellular contacts and polarized features. This breaks the magnificent topology of the developing embryo and, if left unrepaired, can lead to severe tissue disorganization. A recent study demonstrated that cells use the planar cell polarity pathway to reestablish polarity and reintegrate daughter cells into developing tissue.
