Abstract

The contribution of intermediate filaments to the steady state mechanical response of adherent cells was assessed by measuring stiffness in wild-type and vimentin deficient fibroblasts using magnetic twisting cytometry. It was found that in the given range of applied stress, the wild-type cells exhibited greater stiffening than the vimentin-deficient cells. This shows that intermediate filaments contribute to strain-induced stiffening response of adherent cells
