Detailed explanation-1: -Significance: Fibroblasts play a critical role in normal wound healing. Various extracellular matrix (ECM) components, including collagens, fibrin, fibronectin, proteoglycans, glycosaminoglycans, and matricellular proteins, can be considered potent protagonists of fibroblast survival, migration, and metabolism.
Detailed explanation-2: -Fibroblasts are the most common cell type of the connective tissues found throughout the body and the principal source of the extensive extracellular matrix (ECM) characteristic of these tissues.
Detailed explanation-3: -In injured tissues, fibroblasts are activated and differentiate into myofibroblasts, which contract and participate in healing by reducing the size of wound and secreting ECM proteins. The differentiation of fibroblasts to myofibroblasts is a key event in connective tissue wound healing (Fig.
