我们描述了一种使用多参数流细胞测定法来检测小鼠健康造血干细胞和祖细胞(HSPCs)中的线粒体活性氧物种(ROS)和白血病细胞的方法,这些细胞来自急性骨髓性白血病(AML)的小鼠模型。MLL-AF9。

活性氧物种或ROS,是由细胞产生的高活性氧物种,影响它们的行为。虽然过量的ROS也会导致广泛的细胞破坏,在严重的情况下,细胞死亡。因此,维持ROS平衡对细胞功能和生存至关重要。

此处提出的协议侧重于测量由线粒体生成的特定类型的 ROS,主要作为活体、正常或健康的造血干细胞和祖细胞群中的代谢副产物,以及来自血癌、急性骨髓性白血病或 AML 小鼠模型的白血病细胞。该协议还可用于评估基因操作,如基因缺失或过度表达,如何影响线粒体ROS在几个健康和恶性造血种群。因此,可能提供有关重做状态和细胞代谢的有见地的信息。
