Physical model for self-organization of actin cytoskeleton and adhesion complexes at the cell frontTom Shemesh
Department of Molecular Cell Biology, The Weizmann Institute of Science, Rehovot, Israel
Biophys J 102:1746-56. 2012..The model recovers the asynchronous fluctuations and outward bulging of the cell edge, and the dependence of the edge protrusion velocity on the rate of the nascent adhesion generation, the membrane tension, and the substrate rigidity...
Fibroblast polarization is a matrix-rigidity-dependent process controlled by focal adhesion mechanosensingMasha Prager-Khoutorsky
Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot 76100, Israel
Nat Cell Biol 13:1457-65. 2011..We propose that the different stages of cell polarization are regulated by multiple, PTK-dependent molecular checkpoints that jointly control cell contractility and focal-adhesion-mediated mechanosensing...
