Fig. 6: Dynamic traction force of MC3T3-E1 cells on different surfaces.
From: Effects of nanopillars and surface coating on dynamic traction force

Normalized cell traction force and speed as a function of time for MC3T3-E1 cells migrating on PDMS microposts with a flat PDMS, b nanopillars, c silicon oxide, and d titanium oxide. Microposts were coated with FN on top and Pluronic on the sidewalls. The maximum instantaneous speed is indicated.
