细胞表面的糖复合物主要以糖蛋白及糖脂形式存在,是一类重要的信息分子。在细胞的生长、发育、分化、粘附、移动及细胞间识别等基本生命活动中起着广泛的作用。因此,倍受重视。尤其是对肿瘤细胞表面糖复合物与其各种行为间关系的研究,不仅有助于阐明肿瘤的发生、发展规律,提供有效的诊治措施,并为糖复合物作为信息分子和其它功能分子的研究提供了一个理想的模型。由于篇幅所限,文中主要涉及糖蛋白部分。细胞转化与细胞表面糖蛋白的关系 Cell surface glycoconjugates mainly in the form of glycoproteins and glycolipids, is an important class of information molecules. In the cell growth, development, differentiation, adhesion, movement and cell-cell recognition and other basic life activities play a wide range of roles. Therefore, much attention. In particular, the study of the relationship between the carbohydrate complex on the surface of tumor cells and various behaviors not only helps clarify the occurrence and development of tumors, but also provides effective diagnosis and treatment measures, as well as studies on sugar complexes as information molecules and other functional molecules Provided an ideal model. Due to space constraints, the paper mainly involves the glycoprotein part. Relationship between cell transformation and cell surface glycoprotein
