Fibronectin and fibrin gel structure.
Plasma fibronectin is covalently incorporated into alpha-chains of fibrin gels in the presence of Factor XIII activated by thrombin (FXIIIaT) but not by Factor XIII activated by the snake venom enzyme batroxobin (FXIIIaB). FXIIIaB catalyzes introduction of gamma-gamma cross-links in fibrin but cross-linked alpha-chains are not formed. In the presence of FXIIIaT, fibrin gels formed by batroxobin...
متن کاملStudies on the Ultrastructure of Fibrin Lacking
Release of fibrinopeptide B from fibrinogen by copperhead venom procoagulant enzyme results in a form of fibrin ($-f,brin) with weaker self-aggregation characteristics than the normal product (a/9-fibrin) produced by release of fibrinopeptides A (FPA) and B (FPB) by thrombin. We investigated the ultrastructure of these two types of fibrin as well as that of $-fibrin prepared from fibrinogen Met...
متن کاملFibrin gel formation in a shear flow.
Blood clots are made up of platelets and fibrin gel, and the relative amount of fibrin is strongly influenced by the shear rate. In order to explore this phenomenon, this paper presents a model of fibrin gel formation over the surface of an injured blood vessel in a shear flow. A condition for gelation including source and sink terms of polymer is derived. A simplified model of coagulation, inv...

متن کاملConcentration Independent Modulation of Local Micromechanics in a Fibrin Gel
Methods for tuning extracellular matrix (ECM) mechanics in 3D cell culture that rely on increasing the concentration of either protein or cross-linking molecules fail to control important parameters such as pore size, ligand density, and molecular diffusivity. Alternatively, ECM stiffness can be modulated independently from protein concentration by mechanically loading the ECM. We have develope...
