网状纤维是结缔组织细胞间质中的一种纤维,其与胶原纤维及弹力纤维在结缔组织中有机的组合在一起。网状纤维为纤细的纤维,直径为0.2—1微米,由Ⅲ型胶原蛋白构成,由于其分枝相连成网,故名为网状纤维。网状纤维表层包裹有糖蛋白,其具有被银盐浸染的特性,故应用镀银的染色方法能使网状纤维染呈黑色,因而能清晰地将其显示出来,故又称之为嗜银纤维。网状纤维数量的多少、纤维横径的粗细,纤维分布的疏密及范围,对病理诊断具有一定的参考价值,尤其在肿瘤的鉴别诊断、观察基底膜的状态,
Reticular fibers are a type of fiber in connective tissue interstitium that is organically combined with collagen fibers and elastic fibers in connective tissue. Reticular fibers are slender fibers, 0.2-1 μm in diameter, composed of type III collagen, which are called reticular fibers due to their branching into a network. Reticulated fiber surface wrapped with glycoprotein, which has the characteristics of being infected by silver salts, so the application of silver staining method can make the mesh fiber dyed black, which can clearly show it, it is also known as silver fiber. The number of reticular fibers, the thickness of the fiber diameter, the distribution of fiber density and range of pathological diagnosis has a certain reference value, especially in the differential diagnosis of the tumor to observe the status of the basement membrane,
