摘要 目的 研究A-NK/IL-2在完全培养基(CM)和无血清培养基(AIMV)中体外扩增及杀伤肿瘤细胞作用。同时探讨IL-12对于A-NK/IL-2治疗的辅助作用。方法 用MTT法比较不同培养条件下的A-NK细胞体外增殖能力,并测定细胞体外杀伤肿瘤细胞的活性。通过做扫描和透射电镜,对A-NK细胞杀伤的肿瘤细胞进行形态学观察。结果 不同培养条件下的A-NK细胞均可在短期内大量扩增(P>0.05),且均有很强的杀伤肿瘤的活性(P>0.05)。被A-NK细胞杀伤的肿瘤细胞的死亡形式是溶解坏死(necrosis)和凋零坏死(apoptosis)。结论 AIMV可替代CM用于A-NK细胞的培养。联合应用IL-12激活A-NK细胞可降低IL-2的使用剂量,从而避免IL-2带来的副作用。本研究为A-NK细胞的进一步研究和临床应用推广奠定了理论基础。
