Fibrin matrix

The fibrin matrix is a network-like scaffold formed by polymerization of fibrin monomers, which are derived from fibrinogen after enzymatic cleavage by thrombin. This matrix is essential for stabilizing blood clots, facilitating wound healing, and serving as a scaffold for cell growth in tissue engineering. Its viscoelastic properties depend on covalent cross-linking by factor XIIIa, and the matrix can be remodeled by cellular and proteolytic activity (mainly by plasmin)[1][3][6][5][7]. Its mechanical and biochemical environment supports cell adhesion, migration, and proliferation, and its regulated breakdown is crucial for homeostasis and tissue repair[2][4][6]. Fibrin matrix abnormalities are implicated in various diseases, especially those related to thrombosis, cardiovascular pathology, and wound healing defects[1][6]. The term "Fibrin matrix" captures a biological scaffold, not a distinct protein, receptor, or enzyme; therefore, it should not be considered a classical molecular therapeutic target but the context for drug action and biomaterial engineering[1][2][3][6].

Fibrinolytics: Activate plasminogen to plasmin, which degrades the fibrin matrix; Anticoagulants: Prevent thrombin formation, inhibiting conversion of fibrinogen to fibrin; Antiplasmins: Inhibit plasmin, preventing fibrin degradation.
