Recent evidence supports the notion that mitochondrial metabolism is necessary for the determination of stem cell fate. Historically, mitochondrial metabolism is linked to the production of ATP and tricarboxylic acid (TCA) cycle metabolites to support stem cell survival and growth, respectively. However, it is now clear that beyond these canonical roles, mitochondria as signaling organelles dictate stem cell fate and function. In this review, we focus on key conceptual ideas on how mitochondria control mammalian stem cell fate and function through reactive oxygen species (ROS) generation, TCA cycle metabolite production, NAD/NADH ratio regulation, pyruvate metabolism, and mitochondrial dynamics.
最近的证据支持这样一种观点，即线粒体代谢对于干细胞命运的决定是必要的。从历史上看，线粒体代谢与三羧酸 (TCA) 循环代谢物的产生有关，分别支持干细胞的存活和生长。然而，现在很明显，除了这些典型作用之外，线粒体作为信号细胞器决定了干细胞的命运和功能。在这篇综述中，我们重点介绍了关于线粒体如何通过生成活性氧 (ROS)、TCA 循环代谢物产生、NAD/NADH 比调节、丙酮酸代谢和线粒体动力学来控制哺乳动物干细胞命运和功能的关键概念。
