纤维连接蛋白(Fn)是近十几年来受到人们重视的一种高分子糖蛋白,在人体内具有多种功能,如调理素作用,参与细胞对基质的粘附,细胞的展开和排列以维持细胞的形态,以及参与止血和抗血栓过程等。Fn与肿瘤的关系,近来国外进行了大量研究。国内尚未见此类报道。我们对胃癌病人血中的Fn进行了 Fibronectin (Fn) is a high-molecular glycoprotein that has received attention in the past decade. It has a variety of functions in the human body, such as opsonization, participates in cell adhesion to the matrix, and expands and arranges cells to maintain. The morphology of cells, as well as involved in hemostasis and antithrombotic processes. The relationship between Fn and tumors has recently been extensively studied abroad. No such report has been seen in China. We performed Fn in the blood of gastric cancer patients
