English: Incorporation of actin filaments into the contractile ring during furrow induction. Video S3 corresponds to Figure 3A. A surface (cortical) view of furrow induction. Alexa 488 phalloidin-labeled actin filaments were imaged every 10 seconds. Just prior to furrow initiation, some cortical actin filaments began to move toward the spindle equator where they coalesced into nascent bundles within the assembling contractile ring. The arrow tracks the movement of an actin filament or cable as it moved toward the equator, changed its trajectory, and disappeared into the ring. Note the steady increase in fluorescence at the nascent ring due to incorporation of fluorescent actin filaments.
