Dynamics of Cellular Adhesion
Prof. Dr. Pierre-Gilles de Gennes (ESPCI Paris)
Specific Cell adhesion is based on bridging molecules (binders) which can attach to ligands on the opposite surface. During separation, two processes compete : a "tear out" scenario, where some bonds are broken and a "diffusive" scenario, where the number of bonds remains unchanged, but the binders pile up in the remaining contact area. We expect tear out to dominate during separation, but difffusion should control adhesion build up.
