Epigenetic and metabolic remodeling during the acquisition of extended pluripotency

Project description:Totipotent cells with bidirectional chimeric ability attracts more attention from developmental biology and regenerative medicine. Human extended pluripotent stem cells can be obtained and maintained by converting conventional embryonic stem cells using the combo of chemicals, however, the transition and culture system is based on feeder and the mechanism during the acquisition of extended pluripotency is largely unknown. Here we first showed an adapted Matrigel-based feeder-free conversion and maintenance system to generate extended pluripotent stem cells from human embryonic stem cells. We demonstrated the extended pluripotency by molecular markers, chimeric ability and transcriptome. Our data provided an epigenetic and metabolic insight into the maintenance and transition of extended pluripotency.

Diverse development potency and metabolic shape of extended pluripotency are faithfully transferred to somatic cells via cell fusion reprogramming

Project description:Extended pluripotent stem cells (EPSCs) are a novel cell type derived from 8-cell stage embryo or conversion of pluripotent stem cells using a chemical cocktail that blocks the cell fate decision. Previous studies have defined various aspects of EPSCs including dual differentiational potency to both extraembryonic and embryonic lineages, their ability to directly transfer extended pluripotency to differentiated somatic cells by cell fusion remains unelucidated. Here, we sought to determine whether somatic cells could be reprogrammed and obtain extended pluripotency. In this study, newly derived EPSCs are fused with neural stem cells, which is somatic stem cells, by polyethylene glycol (PEG)-mediated method. The resulting hybrid cells exhibited pluripotential properties with upregulated EPSC-specific genes. Also, hybrid cells contributed to the embryonic and extraembryonic lineages in vivo and in vitro. RNA-sequencing analysis confirmed that the global gene expression pattern of hybrid cells are similar to EPSC while there is no expression of NSC markers, indicating complete erasure of somatic memory after fusion reprogramming. Lastly, EPSCs and hybrids exhibited a bivalent energy metabolism phenotype or more active oxidative phosphorylation (OXPHOS) and glycolysis than NSCs. In conclusion, the extended pluripotency of EPSCs could be transferred to somatic cells through fusion-induced reprogramming.

Frequent and Transient Acquisition of Pluripotency During Somatic Cell Trans-Differentiation with iPSCs Reprogramming Factors (RNA-Seq)

Project description:Recent reports have proposed a new paradigm for obtaining mature somatic cell types from fibroblasts without going through a pluripotent state, by briefly expressing canonical iPSC reprogramming factors Oct4, Sox2, Klf4 and c-Myc (abbreviated as OSKM), in cells expanded in lineage differentiation promoting conditions. Here we apply genetic lineage tracing for endogenous Nanog, Oct4 and X chromosome reactivation during OSKM induced trans-differentiation, as these molecular events mark final stages for acquisition of induced pluripotency. Remarkably, the vast majority of reprogrammed cardiomyocytes or neural stem cells derived from mouse fibroblasts via OSKM mediated trans-differentiation were attained after transient acquisition of pluripotency, and followed by rapid differentiation. Our findings underscore a molecular and functional coupling between inducing pluripotency and obtaining “trans-differentiated” somatic cells via OSKM induction, and have implications on defining molecular trajectories assumed during different cell reprogramming methods. poly RNA-Seq was measured before, during and after conversion of mouse embryonic fibroblasts to neural stem cells using OSKM trans-differentiation method.

YY1 safeguard multidimensional epigenetic landscape associated with extended pluripotency

Project description:Although extended pluripotent stem cells (EPSCs) have the potential to form both embryonic and extraembryonic lineages, how their transcriptional regulatory mechanism differs from that of embryonic stem cells (ESCs) remains unclear. Here, we discovered that YY1 binds to specific open chromatin regions in EPSCs. Yy1 depletion in EPSCs leads to a gene expression pattern more similar to that of ESCs than control EPSCs. Moreover, Yy1 depletion triggers a series of epigenetic crosstalk activities, including changes in DNA methylation, histone modifications and high-order chromatin structures. Yy1 depletion in EPSCs disrupts the enhancer-promoter (EP) interactions of EPSC-specific genes, including Dnmt3l. Yy1 loss results in DNA hypomethylation and dramatically reduces the enrichment of H3K4me3 and H3K27ac on the promoters of EPSC-specific genes by upregulating the expression of Kdm5c and Hdac6 through facilitating the formation of CCCTC-binding factor (CTCF)-mediated EP interactions surrounding their loci. Furthermore, single-cell RNA sequencing (scRNA-seq) experiments revealed that YY1 is required for the derivation of extraembryonic endoderm (XEN)-like cells from EPSCs in vitro. Together, this study reveals that YY1 functions as a key regulator of multidimensional epigenetic crosstalk associated with extended pluripotency.
