乳酸是糖酵解的代谢产物之一。它被广泛认为是许多细胞类型的重要能量来源,最近被提出积极参与细胞间通讯。卫星细胞(SCs)是成体骨骼肌干细胞,是骨骼肌再生过程的主要参与者。最近的研究提出了一种代谢开关来增加活化SCs的糖酵解。此外,乳酸在体内和体外均可影响sc和成肌细胞。在这篇简短的综述中,我们描述了代谢变化与SC命运的关系(静止、激活、增殖、迁移、分化、融合和自我更新),并讨论了乳酸作为代谢物和影响SC命运的信号分子之间的可能关系。
Lactate is one of the metabolic products of glycolysis. It is widely accepted as an important energy source for many cell types and more recently has been proposed to actively participate in cell-cell communication. Satellite cells (SCs), which are adult skeletal muscle stem cells, are the main players of the skeletal muscle regeneration process. Recent studies have proposed a metabolic switch to increase glycolysis in activated SCs. Moreover, lactate has been shown to affect SCs and myoblasts in vivo and in vitro. In this short review, we describe how metabolic variations relate with SC fate (quiescence, activation, proliferation, migration, differentiation, fusion, and self-renewal), as well as discuss possible relationships between lactate as a metabolite and as a signaling molecule affecting SC fate.
