ADF/cofilin controls cell polarity during fibroblast migration.
To migrate, normally a cell must establish morphological polarity and continuously protrude a single lamellipodium, polarized in the direction of migration. We have previously shown that actin filament disassembly is necessary for protrusion of the lamellipodium during fibroblast migration. As ADF/cofilin (AC) proteins are essential for the catalysis of filament disassembly in cells, we assessed their role in polarized lamellipodium protrusion in migrating fibroblasts. We compared the spatial...Expand abstract
