NK细胞的纯化及体外扩增是研究NK细胞重要的方法学基础.NK细胞不需在要特异抗原的刺激下即可杀伤肿瘤细胞和病毒感染细胞,它的功能还受多种细胞因子的调节,其中IL-2在体外可显著促进NK细胞的杀伤功能及增殖.本实验在此基础上对NK细胞的生物学特征进行了初步研
Purification and in vitro expansion of NK cells is an important methodological basis for the study of NK cells.NK cells kill tumor cells and virus-infected cells without the stimulation of specific antigens, and their function is regulated by a variety of cytokines , Of which IL-2 in vitro can significantly promote NK cell killing function and proliferation.In this experiment on the basis of the biological characteristics of NK cells were initially studied
