Wnt inhibition confers hESCs a unique transcriptional state compatible with differentiation, but not with derivation

ABSTRACT: Human embryonic stem cells (hESCs) hold great value for future clinical applications. However, standard culture conditions maintain hESCs in a primed state, which bears heterogeneity and a tendency for spontaneous differentiation. To counter these drawbacks, hESCs have been converted to a naive state, but this has in turn restricted the efficiency of existing directed differentiation protocols. We show that adaptation of hESCs to Wnt-inhibiting condition (Wnt-i) conferred a unique transcriptional signature with high levels of pluripotency markers and reduced levels of differentiation markers. Moreover, neuronal and cardiac differentiation of Wnt-i hESCs progressed similarly to primed hESCs, unlike their naïve counterparts. Remarkably, in contrast to mouse, Wnt-i conditions failed to support direct derivation of hESCs, suggesting that active Wnt signaling is required for the transition from inner cell mass to hESCs. Wnt-i hESCs retained advantages of both primed and naive counterparts and may therefore be a better starting point for differentiation towards clinically desired cell types.

Novel culture conditions facilitating the induction of naïve pluripotency in human embryonic stem cells

Project description:We report a novel culture condition inducing naive pluripotency in hESCs in a rapid, robust and reproducible way. These naive hESCs were similar to mESCs exhibiting domed colony morphology, increased single survival, reduced doubling time, upregulation of naive pluripotency-specific genes, unbiased lineage-specific differentiation, hypomethylation, separate clustering profile from parental primed hESCs and were dependent on signalling pathways similar to naive mESCs. Global DNA methylation analysis of naive hESCs and their parental primed hESC counterparts.

PRODH regultes naive pluripotency by influencing mitochondrial oxidative phosphorylation (Targeted metabolomics)

Project description:Naïve human embryonic stem cells (hESCs) that resemble the pre-implantation epiblasts are fueled by a combination of aerobic glycolysis and oxidative phosphorylation, but their mitochondrial regulators are poorly understood. Here we report that, proline dehydrogenase (PRODH), a mitochondria-localized proline metabolism enzyme, is dramatically upregulated in naïve hESCs compared to their primed counterparts. The upregulation of PRODH is induced by a reduction in c-Myc expression that is dependent on PD0325901, a MEK inhibitor routinely present in naive hESC culture media. PRODH knockdown in naive hESCs significantly promoted mitochondrial oxidative phosphorylation (mtOXPHOS) and reactive oxygen species (ROS) production that triggered autophagy, DNA damage, and apoptosis. Remarkably, MitoQ, a mitochondria-targeted antioxidant, effectively restored the pluripotency and proliferation of PRODH-knockdown naïve hESCs, indicating that PRODH maintains naïve pluripotency by preventing excessive ROS production. Concomitantly, PRODH knockdown significantly slowed down the proteolytic degradation of multiple key mitochondrial electron transport chain complex proteins. Thus, we revealed a crucial role of PRODH in limiting mtOXPHOS and ROS production, and thereby safeguarding naïve pluripotency of hESCs.

ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [ATAC-Seq]

Project description:ZIC2 and ZIC3 are essential for acquisition and maintenance of primed pluripotency. In this study, we conducted ATAC-seq in single and compound knockout of ZIC2, ZIC3 and ZIC5 primed hESCs, naïve hESCs lacking ZIC3 that inducibly express ZIC2, naive hESCs that inducible express ZIC2 or ZIC3, ZIC3-depleted primed hESCs that were cultured in 5iLAF medium for six days and undergoing reversion to a naive state, naive hESCs expressing ectopic ZIC2 in the presence of a BRG1 PROTAC.

Human naïve pluripotent stem cells exhibit X chromosome dampening and X-inactivation (single cell RNA-Seq)

Project description:Naïve human embryonic stem cells (hESCs) can be derived from primed hESCs or directly from blastocysts, but their X-chromosome state has remained unresolved. We found that the inactive X-chromosome (Xi) of primed hESCs was reactivated in naïve culture conditions. Similar to cells of the blastocyst, resulting naive cells exhibited two active X-chromosomes with XIST expression and chromosome-wide transcriptional dampening, and initiated XIST-mediated X-inactivation upon differentiation. Both establishment and exit from the naïve state (differentiation) happened via an XIST-negative XaXa intermediate. Together, these findings identify a cell culture system for functionally exploring the two X-chromosome dosage compensation processes in early human development: X-dampening and X-inactivation. Furthermore, the naïve state reset Xi abnormalities of primed hESCs, providing cells better suited for downstream applications. However, naïve hESCs displayed differences to the embryo because XIST expression was predominantly mono-allelic instead of bi-allelic, and X-inactivation was non-random, indicating the need for further culture improvement.

Defining the mechanisms and consequences of glycolytic metabolism in human pluripotent stem cells

Project description:The balance between glycolytic and oxidative metabolism shifts during differentiation of human embryonic stem cells (hESCs) and during reprogramming of somatic cells into pluripotent stem cells. However the contribution of glycolytic metabolism to various stages of pluripotency is not well understood. Additionally, few tools have been developed that modulate pluripotent stem cell glycolytic metabolism to influence self-renewal or differentiation. Here we show that the degree of human pluripotency is associated with glycolytic rate, whereby naive hESCs exhibit higher glycolytic flux, increased MYC transcriptional activity, and elevated nuclear N-MYC levels relative to primed hESCs. Consistently, the inner cell mass of human blastocysts also exhibits increased MYC transcriptional activity relative to primed hESCs and elevated nuclear N-MYC levels. Expression of the lactate transporter, monocarboxylate transporter 1 (MCT1), is strongly associated with the pluripotent state, and reduction of glycolysis using a small molecule inhibitor towards MCT1 decreases self-renewal of naïve hESCs and feeder-free cultured primed hESCs, but not that of primed hESCs grown in feeder-supported conditions. Lastly, reduction of glycolytic metabolism via MCT1 inhibition in feeder-free primed hESCs enhances neural lineage specification. These findings validate the association between glycolytic metabolism and pluripotency, reveal differences in the glucose metabolism of feeder- versus feeder-free cultured hESCs, and show that pharmacologic regulation of glycolysis can influence self-renewal and initial cell fate specification of human pluripotent stem cells.
