Recent advances in metabolomics and computational analysis have deepened our appreciation for the role of specific metabolic pathways in dictating cell fate. Once thought to be a mere consequence of the state of a cell, metabolism is now known to play a pivotal role in dictating whether a cell proliferates, differentiates or remains quiescent. Here, we review recent studies of metabolism in stem cells that have revealed a shift in the balance between glycolysis, mitochondrial oxidative phosphorylation and oxidative stress during the maturation of adult stem cells, and during the reprogramming of somatic cells to pluripotency. These insights promise to inform strategies for the directed differentiation of stem cells and to offer the potential for novel metabolic or pharmacological therapies to enhance regeneration and the treatment of degenerative disease.
近年来,代谢组学和计算分析的进展加深了我们对特定代谢途径在决定细胞命运中的作用的认识。代谢曾经被认为只是细胞状态的结果,而现在已知它在决定细胞是增殖、分化还是静止中起着关键作用。在这里,我们回顾了最近关于干细胞代谢的研究,这些研究揭示了在成体干细胞成熟过程中和体细胞重编程为多能性过程中,糖酵解、线粒体氧化磷酸化和氧化应激之间的平衡发生了变化。这些见解有望为指导干细胞的定向分化提供策略,并为增强再生和治疗退行性疾病提供新的代谢或药理学治疗的潜力。
