Collision of Expanding Actin Caps with Actomyosin Borders for Cortical Bending and Mitotic Rounding in a Syncytium

  • An embryo-wide actomyosin network becomes embedded with circular Arp2/3 domain

  • The Arp2/3 actin caps engage their actomyosin borders for mitotic rounding

  • Each growing actin cap collides with its border and buckles to form furrows

  • Contraction of the embryo-wide myosin network generates forces that swell the caps
