Abstract:
Fibronectin is an adhesive glycoprotein present in a soluble form in plasma and in an insoluble form in the extracellular matrix of many tissues. The human plasma level of this protein is about 300 +/- 100 microg/mL. It is synthesized and secreted by a wide variety of cells, consequently is one of the components of greater distribution in the body that participates in the biochemical reactions of diverse physiological and pathological processes. Due to the presence of multifunctional domains in its structure, fibronectin interacts with diverse components of the coagulation and fibrinolysis. It may bind to collagen, fibrinogen, fibrin, heparin, factor XIII and platelets, among others, regulating processes of importance in hemostasis such as: platelet adhesion and aggregation, tissue remodelling during wound healing, and activation of fibrinolysis by the plasminogen activators.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
