Angelini, T. E., Hannezo, E., Trepat, X., Fredberg, J. J., Weitz, D. A., (2010). Cell migration driven by cooperative substrate deformation patterns Physical Review Letters , 104, (16), 168104

Most eukaryotic cells sense and respond to the mechanical properties of their surroundings. This can strongly influence their collective behavior in embryonic development, tissue function, and wound healing. We use a deformable substrate to measure collective behavior in cell motion due to substrate mediated cell-cell interactions. We quantify spatial and temporal correlations in migration velocity and substrate deformation, and show that cooperative cell-driven patterns of substrate deformation mediate long-distance mechanical coupling between cells and control collective cell migration.
