Plasticity of cell migration: a multiscale tuning model

Cell migration underlies tissue formation, maintenance, and regeneration as well as pathological conditions such as cancer invasion. Structural and molecular determinants of both tissue environment and cell behavior define whether cells migrate individually (through amoeboid or mesenchymal modes) or collectively. Using a multiparameter tuning model, we describe how dimension, density, stiffness, and orientation of the extracellular matrix together with cell determinants-including cell-cell and cell-matrix adhesion, cytoskeletal polarity and stiffness, and pericellular proteolysis-interdependently control migration mode and efficiency. Motile cells integrate variable inputs to adjust interactions among…
