Objective The contribution of actomyosin contractile rings in the wound healing program of somatic cells as never been directly assessed. This contrast with the events characterising the wound healing response of in wounded Xenopus oocytes, in which formation and contraction of an actomyosin ring provides a platform for cytoskeletal repair and drives the restoration of proper plasma membrane composition...
Cytokinesis and single‐cell wound repair both involve contractile assemblies of filamentous actin (F‐actin) and myosin II organized into characteristic ring‐like arrays. The assembly of these actomyosin contractile rings (CRs) is specified spatially and temporally by small Rho GTPases, which trigger local actin polymerization and myosin II contractility via a variety of downstream effectors. We now...
