A study was carried out to compare the apparent stiffness of A549 cells before and after removal of loosely bound bends with centrifugation. It was found that heterogeneous bead behavior produce substantial bias in average cell stiffness, even when large bead torque are applied. The lack of a cell stiffening response during and after repeated twists suggests that deforming stresses do not strengthen the mechanical linkage between cells and beads and do not induce contraction of stress fibers in the A549 alveolar epithelial cell model system.
