Secondary ingression
WebAfter cleavage furrow ingression, the midbody is mechanically stabilized and anchored to the cell cortex by multiple mechanisms (Mierzwa and Gerlich, 2014). The ICB gradually narrows (Guizetti et al., 2011; Schiel et al., 2012) and two constriction zones, also called secondary ingression sites, form at both sides of the midbody
