The study examines the mechanical processes that drive unilateral cytokinesis, focusing on cytoskeletal organization across the cell cycle. High-resolution time-lapse microscopy and quantitative image analysis were used to capture and assess the cellular behaviours.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/2::21::201::201-022::21::201::201-032::21::201::201-06Supplemental data to "A mechanical ratchet drives unilateral cytokinesis"
