Relative timing of intracellular force, pressure and velocity. (a) Estimated range (difference between maximum and minimum across the cell) of the intracellular velocity (red), pressure (green) and force magnitude (blue) for a single cell during a protrusion event. (b) Temporal cross-correlation diagrams between u, p (left), u, u (middle), and u, f (right), representing the lag between quantities (given by the shift of the maximum peak away from 0). (c) Cumulated analysis of the cross-correlation shift over n = 10 cells.
