Plasminogen is a secreted protein that upon cleavage by urokinase plasminogen activator (uPA) or tissue plasminogen activator (tPA) is converted to plasmin, a broad range protease capable of cleaving fibrin and other ECM components. Plasminogen also is a proinflammatory regulator that accelerates the healing of acute and diabetic wounds. Plasminogen can be used in studies of wound healing, inflammation and hypoplasminogenemia.
