WebJan 1, 2024 · Granulation tissue is mainly formed by activated fibroblasts, which synthesize new ECM and help contract the wound (FIGURE 5). It also serves as a scaffold for other cells and components including newly synthesized ECM, new blood vessels, and inflammatory cells. WebDec 18, 2024 · Citation 25 In the granulation tissue, fibroblasts are activated and acquire α-SM actin expression and become myofibroblasts. These myofibroblastic cells synthesize and deposit the ECM components that eventually replace the provisional matrix . These cells exhibit contractile properties, due to the expression of α-SM actin in microfilament ...
