自然杀伤(NK)细胞是近年来新发现的淋巴细胞的一个亚群,其具有自发溶解一些肿瘤细胞的能力。作者以 K562白血病细胞为靶细胞,研究了人骨髓细胞培养中NK细胞活性的维持与调节。该实验用含10%小牛血清(FCS)的RPMI—1640培养液,
Natural killer (NK) cells are a subset of newly discovered lymphocytes in recent years that have the ability to spontaneously lyse some tumor cells. The authors used K562 leukemia cells as target cells to study the maintenance and regulation of NK cell activity in human bone marrow cell culture. In this experiment, RPMI-1640 medium containing 10% calf serum (FCS)
