Microtubules oppose cortical actomyosin-driven membrane ingression during C. elegans meiosis I polar body extrusion.
During C.elegans oocyte meiosis I cytokinesis and polar body extrusion, cortical actomyosin is locally remodeled to assemble a contractile ring that forms within and remains part of a much larger and actively contractile cortical actomyosin network.This network both mediates contractile ring dynamics and generates shallow ingressions throughout kai
