病毒必须依赖敏感的活细胞才能复制。对细胞的种类 ,病毒常常有一定、甚至是十分严格的选择性。体外的病毒感染细胞试验 ,不但是研究病毒致病机理的重要途径 ,也是分离和鉴定病毒的常用的方法。肿瘤细胞系的建议 ,为研究病毒提供了非常有用的实验材料。我们用万启惠等建立的卵 Viruses must rely on sensitive living cells for replication. Of the kinds of cells, viruses often have a certain, even very strict selectivity. In vitro virus-infected cells test, not only is an important way to study the pathogenesis of the virus, but also a common method for the isolation and identification of viruses. The recommendations of tumor cell lines provide very useful experimental materials for studying viruses. We use Wan Qi Hui and other eggs
