Cytokinesis, the final stage of the cell cycle, is an essential step toward the formation of two viable daughter cells. In recent years, membrane trafficking has been shown to be important for the completion of cytokinesis. Vesicles originating from both the endocytic and secretory pathways are known to be shuttled to the plasma membrane of the ingressing cleavage furrow, delivering membrane and proteins to this dynamic region. Advances in cell imaging have led to exciting new discoveries regarding vesicle movement in living cells. Recent work has revealed a significant role for membrane trafficking, as controlled by regulatory proteins, during cytokinesis in animal cells. The endocytic and secretory pathways as well as motor proteins are revealed to be essential in the delivery of vesicles to the cleavage furrow during cytokinesis.
