背景药物敏感性通常通过利用集落形成来区分存活和致死处理的细胞的测定来确定。这些测定需要具有形成可辨别的集落的高平板接种效率的细胞,耗时且费力,并且需要手动计数大量集落。为了克服这些缺点,我们开发了一种流式细胞术技术,测定生存的增殖能力在cultured cells.MethodsLabeling与bromodeoxyuridine为72小时,然后由双变量Hoechst 33258/溴化乙锭流式细胞术允许歧视nonproliferating细胞从那些已经经历了一到三个分裂。加入内标物鸡红细胞核,可测定总细胞数。为了验证我们的分析,我们使用流式细胞术和集落形成试验来确定来自沃纳综合征患者和未受影响个体的细胞系对4-硝基喹啉-1-氧化物(4 NQO)的敏感性结果流式细胞术和集落形成试验对每种药物的敏感性相当,并且Werner综合征细胞表现出的药物敏感性增加基本相同。菌落形成试验的替代品。流式技术还将有助于分析不适合集落形成试验的细胞中的药物敏感性。Cytometry 48:1-5,2002.© 2002 Wiley利斯公司
BackgroundDrug sensitivity is commonly determined by assays that utilize colony formation to discriminate between surviving and lethally treated cells. These assays require cells with high plating efficiency that form discernible colonies, are time‐consuming and laborious, and require manual counting of large numbers of colonies. To overcome these drawbacks, we developed a flow cytometric technique that assays survival of proliferative capacity in cultured cells.MethodsLabeling with bromodeoxyuridine for 72 h followed by bivariate Hoechst 33258/ethidium bromide flow cytometry allows discrimination of nonproliferating cells from those that have undergone one to three divisions. Addition of an internal standard, chicken erythrocyte nuclei, permits determination of total cell number. To validate our assay, we used flow and colony‐forming assays to determine the sensitivity of cell lines derived from Werner syndrome patients and unaffected individuals to 4‐nitroquinoline‐1‐oxide (4NQO) and camptothecin.ResultsThe flow and colony‐forming assays yielded comparable sensitivity for each drug and essentially identical increases in drug sensitivity exhibited by Werner syndrome cells.ConclusionOur results indicate that the flow assay is a less laborious surrogate for colony‐forming assays. The flow technique will also facilitate the analysis of drug sensitivity in cells that are not amenable to colony‐forming assays. Cytometry 48:1–5, 2002. © 2002 Wiley‐Liss, Inc.
