We quantified actin filament order in human cells using fluorescence polarization microscopy and found that cleavage furrow ingression initiates by contraction of an equatorial actin network with randomly oriented filaments. The network subsequently gradually reoriented actin filaments along the cell equator. This strictly depended on myosin II activity, suggesting local network reorganization by mechanical forces. Cortical laser microsurgery revealed that during cytokinesis progression, mechanical tension increased substantially along the direction of the cell equator, while the network contracted laterally along the pole-to-pole axis without a detectable increase in tension. Our data suggest that an asymmetric increase in cortical tension promotes filament reorientation along the cytokinetic cleavage furrow, which might have implications for diverse other biological processes involving actomyosin rings.","lang":"eng"}],"file":[{"relation":"main_file","checksum":"ba09c1451153d39e4f4b7cee013e314c","file_name":"IST-2017-919-v1+1_elife-30867-figures-v1.pdf","access_level":"open_access","creator":"system","content_type":"application/pdf","date_updated":"2020-07-14T12:47:10Z","date_created":"2018-12-12T10:10:40Z","file_size":9666973,"file_id":"4829"},{"date_created":"2018-12-12T10:10:41Z","file_size":5951246,"file_id":"4830","date_updated":"2020-07-14T12:47:10Z","file_name":"IST-2017-919-v1+2_elife-30867-v1.pdf","access_level":"open_access","creator":"system","content_type":"application/pdf","relation":"main_file","checksum":"01eb51f1d6ad679947415a51c988e137"}],"type":"journal_article","license":"https://creativecommons.org/licenses/by/4.0/","day":"06","month":"11","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2023-02-23T12:30:29Z","quality_controlled":"1","title":"Cytokinesis in vertebrate cells initiates by contraction of an equatorial actomyosin network composed of randomly oriented filaments","status":"public","oa":1,"oa_version":"Published Version","date_created":"2018-12-11T11:47:14Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"eLife Sciences Publications","scopus_import":1}
