Peripheral microtubules (MTs) near the cell cortex are essential for the positioning and continuous constriction of the contractile ring (CR) in cytokinesis. Time-lapse observations of Drosophila male meiosis showed that myosin II was first recruited along the cell cortex independent of MTs. Then. shortly after peripheral MTs made contact with the equatorial cortex. https://fitnessgravesyardes.shop/product-category/leveling-foot/
