It marks the beginning of the cell’s “pinching” its cell membrane and cytoplasm down the middle. In cell biology the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage by which animal and some algal cells undergo cytokinesis the final splitting of the membrane in the process of cell division. The same proteins responsible for muscle contraction actin and myosin begin the process of forming the cleavage furrow creating an actomyosin ring. Other cytoskeletal proteins and actin binding proteins are involved in the procedure. During cytokinesis in animal cells the cleavage furrow is positioned by microtubules from two sides of the cell that interact at the cell midplane and recruit proteins that signal to the actin cortex to induce cortical contraction . A cleavage furrow is found in animal cells while cell plates form in plant cells . A cleavage furrow on the outer surfa...
