To explore minimal cell division machinery, I encapsulated actin and myosin inside giant unilamellar vesicles (GUVs). By tuning a few biochemical parameters, the networks self-organized into contractile rings that squeezed and deformed the vesicles, producing furrow-like constrictions. This system provides a stripped-down model for studying how cytoskeletal forces reshape membranes during cell division.adas
