Rigidity sensing is related to the strength of FN bead linkages to the cytoskeleton and is RPTPα dependent. (A) Schematic graph showing the position of rigid or soft trap on the lamellipodia of a spreading cell. (B) Breaking percentage of FN beads placed on the lamellipodia of RPTPα+/+ cells. (C) Breaking percentage of FN beads placed on the lamellipodia of RPTPα−/− cells. Results shown are the mean ± SD of three independent experiments. Asterisks indicate significant statistical difference between the two groups, p < 0.01.
