abstract = {The spatially ordered formation and disassembly of focal
adhesions is a basic requirement for effective cell
locomotion. Because focal adhesions couple the contractile
actin-myosin network to the substrate, their distribution
determines the pattern of traction forces propelling the
cell in a certain direction. In the present study, we
quantitatively analyzed the spatial patterning of
cell-substrate adhesion in migrating cells by mapping
averaged focal adhesion growth dynamics to a standardized
cell coordinate system. These maps revealed distinct zones
of focal adhesion assembly, disassembly and stability and
were strongly interrelated with corresponding actin flow and
traction force patterns. Moreover, the mapping technique
enables precise detection of even minute responses of
adhesion dynamics upon targeted signaling perturbations. For
example, the partial inhibition of vinculin phosphorylation
was followed by the reduced number of newly formed
adhesions, whereas growth dynamics of existing adhesions
remained unaffected.},
