  5. The characteristics of this method are : a, directly counting cell number without the influence of the metabolic state of the cells ; b, discrimination of target cells from effector cells in cell - mediated cytotoxicity assay ; c, less treatment step, and free - radioactivity ; d, high sensitivity and reliability. 2, using the above assay, immunofluorescent labeled technique, and flow cytometry, the pbmc proliferation, apoptosis, necrosis, cell cycle, activation, cytokines and membrane marker were detected. the results showed that the number of pbmc reduced, but the activity of pbmc increased dose - dependently ; the reduction of cell number resulted from necrosis and apoptosis ; the supernatant of k562 cell lines were not able to block the cell cycle, but to promote it ; the ratio of t cell subset and the expression of thl and th2 cytokines increased

    結合以上創建的方法和免疫熒光流式細胞術，用k562細胞株可溶性分泌物（上清）對外周血單個核細胞（ pbmc ）進行培養以模擬體內微環境，然後分別從細胞增殖、凋亡、壞死、細胞周期、活性、細胞因子和表面抗原表達等方面進行研究，結果發現用腫瘤上清培養的pbmc細胞數量下降明顯，但同時對其有激活作用，且呈劑量依賴性；細胞數的下降主要是由細胞壞死和凋亡引起的，腫瘤上清對細胞周期沒有阻斷作用，反而略有促進作用； t細胞亞群比例增加，並促進表達th1 、 th2細胞因子。
