Cytokinesis occurs through the coordinated action of several biochemically-mediated stresses acting on the cytoskeleton . Here , we develop a computational model of cellular mechanics , and using a large number of experimentally measured biophysical parameters , we simulate cell division under a number of different sce... | Cytokinesis , the physical separation of a mother cell into two daughter cells , requires force to deform the cell . Though there is ample evidence in many systems that myosin II provides some of this force , it is also well known that some cell types can divide in the absence of myosin II . To elucidate the mechanisms... | [
