在这里,我们提出了一种准确可靠地测量稀有细胞类型中代谢物的方案。技术改进,包括用于细胞分选的改良鞘液和相关空白样品的生成,能够对代谢物进行全面定量,每个样品的起始量仅为 5000 个细胞。
我的实验室的主要目标是在衰老过程中保持健康的造血干细胞,以避免血液系统恶性肿瘤,我们通过进行饮食干预来实现这一目标。因此,我们特别有兴趣了解饮食衍生代谢物如何调节干性,以及细胞内代谢物如何调节干细胞命运。造血干细胞是一个非常罕见的群体,这意味着我们总是面临没有足够的材料来进行实验的挑战。
但现在随着单细胞方法的建立,以及低输入方法的建立,我们对这些干细胞是如何调节的有了新的认识。造血干细胞是一个非常罕见的群体,最重要的是,它们非常小。现在,通过我们开发的方法,例如基于质谱的低输入代谢组学,我们现在可以检测非常少的细胞数量,数百种代谢物,这使我们能够了解某些代谢物对干细胞调节的作用。
