摘要
Dear Editor,Embryonic stem cells(ESCs)have been assumed to possess immature mitochondria and to favor anaerobic glycolysis over oxidative phosphorylation(OXPHOS)for energy production.This proposition is largely based on the findings that ESCs possess globular mitochondria with blurred cristae,and the facts that ESCs have higher glycolysis activity and lower mitochondrial respiration capacity than somatic cells(Kondoh et al.,2007;Folmes et al.,2011,2012;Zhang et al.,2012;Xu et al.,2013;Ito and Suda,2014;Gu et al.,2016).However,recent studies have shown that mitochondrial autophagy and mitochondrial dynamics are pivotal for ESC self-renewal and pluripotency(Todd et al.,2010;Liu et al.,2016,2020;Wang et al.,2019;Zhong et al.,2019).These studies have raised a fundamental question:what is the contribution and functional mechanism of mitochondrial respiration in pluripotency regulation?
