“…Interestingly, hESC-specific downregulated genes were highly enriched in ion/cation transport and metabolism ( Figure 3A). Metabolism was recently proved to be a critical aspect of the unique energetic and biosynthetic programs associated with ESCs' self-renewal [34,35]. Indeed, many actively expressed metabolic genes with reported or unknown roles in ESC maintenance were targeted by SOX2.…”

SOX2 is a key regulator of multiple types of stem cells, especially embryonic stem cells (ESCs) and neural progenitor cells (NPCs).Understanding the mechanism underlying the function of SOX2 is of great importance for realizing the full potential of ESCs and NPCs. Here, through genome-wide comparative studies, we show that SOX2 executes its distinct functions in human ESCs (hESCs) and hESC-derived NPCs (hNPCs) through cell type-and stage-dependent transcription programs. Importantly, SOX2 suppresses non-neural lineages in hESCs and regulates neurogenesis from hNPCs by inhibiting canonical Wnt signaling. In hESCs, SOX2 achieves such inhibition by direct transcriptional regulation of important Wnt signaling modulators, WLS and SFRP2. Moreover, SOX2 ensures pluripotent epigenetic landscapes via interacting with histone variant H2A.Z and recruiting polycomb repressor complex 2 to poise developmental genes in hESCs. Together, our results advance our understanding of the mechanism by which cell type-specific transcription factors control lineage-specific gene expression programs and specify cell fate.

“…A few recent review articles provide a comprehensive overview of the burgeoning field of metabolism research in stem cells. [2][3][4][5] Even though this field is fairly young, the broad area of "cellular metabolism" refers to a vast and complex interplay of various anabolic and catabolic pathways. Since the recognition that not only do undifferentiated stem cells and mature stem cells have distinct metabolic phenotypes but the metabolic pathways are mechanistically involved in the differentiation processes, research groups have attempted to target a plethora of metabolic pathways in stem cells.…”

Two defining characteristics of stem cells are their multilineage differentiation potential (multipotency or pluripotency) and their capacity for self-renewal. Growth factors are well-established regulators of stem cell differentiation and self renewal, but less is known about the influence of the metabolic state on stem cell function. Recent studies investigating cellular metabolism during the differentiation of adult stem cells, human embryonic stem cells (ESCs), and induced pluripotent stem cells have demonstrated that activation of specific metabolic pathways depends on the type of stem cells as well as the lineage cells are differentiating into and that these metabolic pathways can influence the differentiation process. However, some common patterns have emerged, suggesting that undifferentiated stem cells primarily rely on glycolysis to meet energy demands. Our own data indicate that undifferentiated ESCs not only exhibit a low mitochondrial membrane potential but also express high levels of the mitochondrial uncoupling protein 2 and of glutamine metabolism regulators when compared with differentiated cells. More importantly, interventions that target stem cell metabolism are able to either prevent or enhance differentiation. These findings suggest that the metabolic state of stem cells is not just a marker of their differentiation status but also plays an active role in regulating stem cell function. Regulatory metabolic pathways in stem cells may thus serve as important checkpoints that can be modulated to direct the regenerative capacity of stem cells.
