Cell contraction induces long-ranged stress stiffening in the extracellular matrix by Ronceray, Pierre, Lenz, Martin, Broedersz, Chase P., han, yulong, Xu, Guoqiang, Guo, Ming, Malandrino, Andrea, Kamm, Roger Dale

“…We decipher this remarkable behavior by introducing nonlinear stress inference microscopy (NSIM), a technique to infer stress fields in a 3D matrix from nonlinear microrheology measurements with optical tweezers. Using NSIM and simulations, we reveal large long-ranged cell-generated stresses capable of buckling filaments in the matrix. …”
