Mechanical Strain Regulates Myofibroblast Differentiation of Human Scleral Fibroblasts by YAP

open access: yesFrontiers in Physiology, 2021
Scleral extracellular matrix (ECM) remodeling is thought to play a critical role in the pathogenesis of glaucoma. Mechanical strain induced by elevated intraocular pressure can promote myofibroblast differentiation of fibroblasts and result in scleral ...
