Effective tissue engineering requires appropriate selection of cells and scaffold, where the latter serves as a mechanical and biological support for cell growth and functionality. The optimal combination of cell source and scaffold properties can vary for each desired application. Such preconditions necessitate enhanced understanding of the interactions between cells and scaffold within engineered tissue. Several studies have examined the deforming effects cells induce in scaffolds via exertion of contractile forces. In contrast, other studies focus on the scaffold's biochemical and mechanical properties and their effects on cell behavior. This review summarizes the mechanical interplay between cells and scaffold within engineered tissue. We present evidence for contractile forces exerted by cells on three-dimensional (3D) scaffolds and discuss existing methods for their quantification. In addition, we address some theories related to the effects of scaffold stiffness and mechanical stimulation on cell behavior. Further understanding of the reciprocal effects between cells and scaffold will provide both enhanced knowledge regarding the expected properties of engineered tissue and more competent tissue regeneration techniques.
