Anisotropic traction stresses and focal adhesion polarization mediates topography-induced cell elongation

Published date : 30 Jul 2018

Cell elongation and differentiation has been shown to be modulated by topographical cues provided by grating substratum. However, little is known about the mechanisms and forces involved in the grating-induced cell elongation, due to the difficulty in fabricating soft elastic gels that allow 3-dimensional (3D) cell traction stress measurements. In this paper, we present a method to fabricate soft elastic polyacrylamide grating substrates, using an imprinted polyethylene terephthalate mould, for 3D cell traction stress measurements.
