摘要 目的:探讨一种适于晚期恶性肿瘤治疗的自体外周血造血干细胞移植方法。方法:单用rG-CSF(75μg,q12h×2d)作动员剂,用血细胞分离机一次性收集单个核细胞(MNC),4℃贮存。观察WBC、MNC计数、细胞活力及细胞分类;用流式细胞仪进行细胞表型检测。结果:小剂量rG-CSF动员后,外周血WBC达(18.71±6.54)×109 /L。一次可收集MNC(1.87±0.66)×108 /kg。CD34 、CD14 、CD3 及CD22 细胞分别为4.39%、3.85%、4.63%及3.76%。CD34细胞平均约为8.2×106 /kg。4℃贮存48~56小时MNC存活率为94.3%。结论:对实体瘤尚无骨髓转移的患者,用此方法可获得足以重建造血功能的干细胞。

Abstract Objective:To probe the way of autologous peripheral blood stem cell transplantation (APBSCT) for treatment of advanced malignant tumor.Methods:The peripheral blood stem cells were mobilized by rG-CSF (75ug q12h x 2d) and isolated by CS-3000 Plus Blood Cell Seperator and stored at 4℃ for 48~56 hrs.The number of WBC and MNC and cell vibility were counted and classified by BVPM multi-microscope and CD34 ,CD14 ,CD3 and CD22 were determined by flow microfluorometer.Results:After mobilization by G-CSF,the number of WBC increased to 18.71±6.54× 109 /L (averagely 3.23 times of that before mobilized).MNC was 1.87±0.66×109 Kg and CD34 cell number was 8.2× 106 /Kg.The positive rates of CD34 ,CD14 ,CD3 and CD22 were 4.39%,3.85%,4.63% and 3.76% respectively.The survival rate of MNC at 4℃ was 94.3%.Conclusion:The results showed that mobilized APBSC stored at 4℃ is helpful for the patients with solid malignant tumor to get reconstructed hemopoietic function under high dose chemotherapy.
