Methods Proliferation, cytotoxicity in vitro and expression of CD11C of the cells cultured in the two different media were compared. To observe the tumor target cells killed by adherent natural killer cells (A-NK) through electroscope.

• 方法分别用AIMV及完全培养基培养粘附NK细胞(A-NK)和非粘附NK细胞(NA-NK),比较细胞的增殖能力、杀伤肿瘤细胞的能力、表达粘附分子CD11C的能力,并通过电镜对A-NK细胞所杀伤的肿瘤细胞进行形态学观察。
