Cell leading edge是什么
Webincreases, there is a decrease in cell edge velocity, followed by progressive shortening of the lamellipodium and actin re-inforcement at the cell edge (Dubin-Thaler et al., 2004, 2008; Gauthier et al., 2011; Masters et al., 2013). When membrane tension subsequently decreases, the cell edge resumes protru-sion (Gauthier et al., 2011). WebMay 13, 2015 · Cell motility relies on the continuous reorganization of a dynamic actin-myosin-adhesion network at the leading edge of the cell, in order to generate protrusion at the leading edge and traction between the cell and its external environment. We analyze experimentally measured spatial distributions o …

WebDorsal stress fibers in motile cells are formed from actin filament bundles that are initiated and extended from cell-substrate adhesions at the leading edge (aka focal complexes. Initiation is triggered by the activation of adhesion molecules, such as integrin, and the tension-dependent recruitment and activation of the Rho family of GTPases ...
