Nanomechanical Characterization of the Stiffness of Eye Lens Cells: A Pilot Study

Abstract

We found that single cells from the lens nucleus and cortex can be distinguished unambiguously using the elastic modulus as a criterion. The uncommon maintenance of shape and elastic properties after cell isolation together with the null effect of actin filaments and microtubules targeting drugs suggest that the mechanical stability of fiber cells is provided by cellular elements other than the usual cytoskeletal proteins.
