Abstract
Aberrant deposition of the extracellular matrix (ECM) causes fibrosis and leads to ECM stiffening. This fibrotic ECM provides biological and biophysical stimulations to alter cell activity and drive progression of fibrosis. As an emerging discipline, mechanobiology aims to access the impact of both these cues on cell behavior and relates the reciprocity of mechanical and biological interactions; it incorporates concepts from different fields, like biology and physics, to help study the mechanical and biological facets of fibrosis extensively. A useful experimental platform in mechanobiology is decellularized ECM (dECM), which mimics the native microenvironment more accurately than standard 2D culture techniques as its composition includes similar ECM protein components and stiffness. dECM, therefore, generates more reliable results that better recapitulate in vivo fibrosis.
