The actomyosin ring generates force to ingress the cytokinetic cleavage furrow in animal cells. yet its filament organization and the mechanism of contractility is not well understood. 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 random... https://foldlyers.shop/product-category/bluetooth-transmitters/
