To rapidly restore mechanical integrity of tissues after injury, a variety of different cell types are activated to become myofibroblasts. Hallmarks of the myofibroblast are secretion of extracellular matrix (ECM), development of adhesion structures with the ECM, and formation of contractile stress fiber bundles. When contracture and ECM remodeling become progressive and manifest as organ fibrosis, stiff scar tissue obstructs and ultimately destroys organ function. Pivotal for the formation and persistence of myofibroblasts are mechanical stimuli arising during tissue repair and chronic persistence of inflammatory cells. I will give an overview on our current projects that address how mechanical factors orchestrate the development of myofibroblasts by mediating direct and far/ranging communication between myofibroblasts and macrophages. By understanding and manipulating myofibroblast and macrophage mechanoperception we will be able to devise better therapies to reduce scarring and support normal wound healing.
