Summary Hypertrophic scars/keloids are pathogenic scars that are characterized by collagen and fibroblast accumulation. The endothelia in the lesions are mechanosensitive and participate actively in the pathogenesis of these scars. The present review summarizes how endothelium responds to mechanical stimuli such as shear, stretch and hydrostatic pressure. It also shows that in heart, liver, kidney and lung fibrosis, endothelial dysfunctions ( ED s) associate with changes in vascular tone, endothelial permeability, coagulation and vasomodulation that result in inflammation, hypertension and coagulation. Pathological scars exhibit similar ED s during their development and progression. Mechanopharmaceutical or mechanotherapeutic interventions that rescue ED s may be useful scar treatments.
