Mechanical properties of α5β1^high and α5β1^low cells. (A) Stiffness of α5β1^high and α5β1^low cells measured during increasing force application to fibronectin-coated beads. (B) Power-law exponent b (cell fluidity) of α5β1^high and α5β1^low cells versus force applied to fibronectin-coated beads. The values are expressed as mean ± s.e.m. (C–E) MSD of spontaneous bead motion (C) showed a higher apparent diffusivity (D) and a higher persistence (power-law exponent β) (E) in α5β1^high cells than in α5β1^low cells. *P<0.05, ***P<0.001.
