WebWe investigated the dynamics of cell-cell junction formation and the corresponding architecture of the underlying cytoskeleton in cultured human umbilical vein endothelial cells. We show that the initial interaction between cells is mediated by protruding lamellipodia. On their retraction, cells maintain contact through thin bridges formed by ... WebAt cell– cell junctions, cells receive, generate, and integrate contractile forces. 86 The ability to resist force is essential for maintaining tissue integrity, and there is increasing evidence that cells actively respond to tensile force by reinforcing adhesion. 87,88 One manifestation of contractility is the generation of tension in junctions, as revealed by the retraction that …
WebOct 13, 2024 · We have studied two types of cell motility directed toward the cell center: retraction of the cell margin and rearward flow of small cytoplasmic nodules during mitotic cell rounding in Potoroo tridactylis kidney (PtK2) cells by time-lapse video microscopy, drug treatments, and photoactivation of fluorescence. Nodules flow rearward on thin, actin-rich … WebFeb 20, 2024 · Developmental and Stem Cell Biology Program, The Arthur and Sonia Labatt Brain Tumour Research Centre, Division of Neurosurgery, Departments of Surgery, …
