The extracellular matrix operates across timescales, from polymer chains that rearrange over seconds to hours to tissues that remodel over a lifespan. While stiffness describes resistance to deformation, stress relaxation describes how that resistance decreases over time, and strain stiffening describes how that resistance increases with continued deformation. These competing polymer and tissue-scale dynamics occur simultaneously, raising the question of what stiffness a cell experiences. At any given moment, is the cell experiencing a ‘stiff ’ or a ‘soft’ environment? To address this, we developed an empirical model that separates stress relaxation and strain stiffening timescales.
