– Plasminogen is a zymogen secreted as a precursor protein that, when cleaved by urokinase plasminogen activator (uPA) or tissue plasminogen activator (tPA), is converted into plasmin. Plasmin is a protease with broad specificity, capable of degrading fibrin and various extracellular matrix (ECM) components. Additionally, plasminogen functions as a proinflammatory regulator, promoting the healing of both acute and diabetic wounds. It is utilized in research related to wound healing, inflammation, and hypoplasminogenemia [1] [2].
