Fig. 5.

Scatter plot showing cell translational velocity as a function of cell body to substrate seperation distance (distance does not include microvilli-see inset). Instantaneous changes in the separation distance are seen as individual traces. The asterisk indicates the trace representing the first approach of the cell to the substrate. The almost vertical trace for the high translational velocities represents instantaneous changes in the separation distance when no load-bearing bonds were present. The trace discontinuity near velocity zero is due to a discrete process of modeling owing to the time step. Unpublished data (Pospieszalska and Ley).
