Plasminogen, derived from human plasma, is primarily used in medical and therapeutic applications. It plays a crucial role in the fibrinolytic system, where it is converted into plasmin, an enzyme that breaks down blood clots. This property makes it essential in treating conditions like thromboembolic disorders, where abnormal blood clots can obstruct blood flow. It is also utilized in research to study clot dissolution mechanisms and develop treatments for cardiovascular diseases. Additionally, plasminogen is investigated for its potential in wound healing and tissue repair, as it aids in the breakdown of fibrin and promotes cell migration and regeneration. In clinical settings, it may be used in combination with other therapies to enhance recovery in patients with severe clotting issues.
