The mitotic spindle provides the spatial cue that coordinates cytokinesis with nuclear division. However, the specific property of the mitotic spindle that mediates this spatial regulation remains obscure, in part because different aspects of the mitotic spindle appear to have furrow inducing activity in different systems. We show that in C. elegans embryos, although the central spindle is usually dispensable for furrow initiation, it becomes essential for furrow formation when the extent of centrosome separation during anaphase is reduced. Measurements of microtubule density demonstrate that furrow formation occurs in the vicinity of a local minimum of microtubule density. Reduction of the extent of spindle elongation or disruption of the central spindle causes delayed formation of the cleavage furrow. These data suggest that reduced microtubule density triggers cleavage furrow initiation and demonstrate that redundant mechanisms direct efficient formation of the cleavage furrow.
