Schematic representation of major reactions in blood induced by biomaterial surface. Besides complement system, intrinsic and extrinsic coagulation pathway can be activated. Coagulation activation results in generation of a fibrin network. Furthermore, platelets can adhere and aggregate on the surface. The adhesion and activation of leukocytes can lead to the release of polymorphonuclear (PMN) elastase and tissue factor (TF) and result in activation of extrinsic pathway. ADP, Adenosine diphosphate; β-TG, β-Thromboglobulin; GPIIb/IIIa, Glycoprotein IIb/IIIa; MAC, Membrane attack complex; PF4, Platelet factor 4; TXA2, Thromboxane A2; vWF, von Willebrand factor.
