摘要 目的 :探讨脐血CIK细胞体外增殖活性及对K5 62细胞的杀伤活性。方法 :通过第 1天在脐血淋巴细胞中加入IFN γ ,第 2天再加入IL 2和CD3单抗进行细胞培养 ,就可获得名为多种细胞因子诱导的杀伤细胞 (cy tokineinducdekillercells)即脐血CIK细胞。用MTT法测定其抗肿瘤活性 ,台盼蓝拒染法计数细胞。结果 :脐血CIK细胞及其培养上清抗K5 62细胞活性明显优于CD3AK细胞 ,短期培养后其增殖活性低于CD3AK细胞 ;但是G CSF的加入可以提高CIK细胞的增殖活性。结论 :脐血CIK细胞是一种有效的杀伤活化细胞 ,脐血在多种细胞因子适当组合的诱导下即可提高杀瘤活性 ,又能保留重建造血功能的作用。
