纤维蛋白原是凝血级联反应的主要成分之一,在组织损伤后迅速形成不溶于水的基质。除了在止血方面的重要作用外,纤维蛋白还充当组织修复的支架,并为指导损伤后的细胞表型提供重要线索。由于纤维蛋白的这些性质和材料易于聚合,一个多世纪以来,纤维蛋白已被广泛用作生物材料。直到最近,改变纤维蛋白的宏观性质,如弹性和孔隙率,一直有些难以捉摸,但通过分子水平的合理设计方法,现在可以通过改变蛋白质聚合过程中关键的分子相互作用来进行某种程度上的容易修改。本文概述了纤维蛋白的生物化学,讨论了分子间相互作用的修饰方法及其在纤维蛋白生物材料中的应用。
Fibrinogen is one of the primary components of the coagulation cascade and rapidly forms an insoluble matrix following tissue injury. In addition to its important role in hemostasis, fibrin acts as a scaffold for tissue repair and provides important cues for directing cell phenotype following injury. Because of these properties and the ease of polymerization of the material, fibrin has been widely utilized as a biomaterial for over a century. Modifying the macroscopic properties of fibrin, such as elasticity and porosity, has been somewhat elusive until recently, yet with a molecular-level rational design approach can now be somewhat easily modified through alterations of molecular interactions key to the protein’s polymerization process. This review outlines the biochemistry of fibrin and discusses methods for modification of molecular interactions and their application to fibrin based biomaterials.
