近几年,导向药物的研究在肿瘤治疗领域受到重视。但药物在体外实验的结果必须经过动物体内模型以确定这种生物导弹在体内的效力.因此,建立人类肿瘤细胞裸鼠模型并观察移植瘤表面抗原是否稳定表达是十分重要的. In recent years, the research of drug-directed drugs has received attention in the field of cancer treatment. However, the results of drug in vitro experiments must be through the animal model to determine the effectiveness of the biological missile in vivo. Therefore, it is very important to establish a human tumor cell nude mouse model and observe whether the surface antigen of the tumor is stably expressed.
