Project description:Mouse embryonic stem (ES) cells are isolated from the inner cell mass of blastocysts, and can be preserved in vitro in a naive inner-cell-mass-like configuration by providing exogenous stimulation with leukaemia inhibitory factor (LIF) and small molecule inhibition of ERK1/ERK2 and GSK3b signalling (termed 2i/LIF conditions). Hallmarks of naive pluripotency include driving Oct4 (also known as Pou5f1) transcription by its distal enhancer, retaining a pre-inactivation X chromosome state, global reduction in DNA methylation and in H3K27me3 repressive chromatin mark deposition on developmental regulatory gene promoters.Upon withdrawal of 2i/LIF, naM-CM-/ve mouse ES cells can drift towards a primed pluripotent state resembling that of the post-implantation epiblast. Although human ES cells share several molecular features with naive mouse ES cells, they also share a variety of epigenetic properties with primed murine epiblast stem cells (EpiSCs). These include use of the proximal enhancer element to maintain OCT4 expression, pronounced tendency for X chromosome inactivation in most female human ES cells, increase in DNA methylation and prominent deposition of H3K27me3 and bivalency acquisition on lineage regulatory genes. The feasibility for establishing human ground state naive pluripotency in vitro with equivalent molecular and functional features to those characterized in rodent ES cells remains to be defined. Here we establish defined conditions that facilitate the derivation of genetically unmodified human naive pluripotent stem cells from already established primed human ES cells, from somatic cells through induced pluripotent stem (iPS) cell reprogramming or directly from blastocysts. The novel naive pluripotent cells validated herein retain molecular characteristics and functional properties that are highly similar to mouse naive ES cells, and distinct from conventional primed human pluripotent cells. This includes competence in the generation of cross-species chimaeric embryos that underwent organogenesis following microinjection of human naive iPS cells into mouse morulas. Collectively, our findings establish new avenues for regenerative medicine, patient-specific iPS cell disease modelling and the study of early human development in vitro and in vivo. Total of 12 samples of naM-CM-/ve and primed human ESC lines were analyzed for gene expression. Many of the lines analyzed are genetically matched (H9, WIBR3).

Project description:Mouse naive and primed pluripotent stem cells, ESC and EpiSC, represent two distinct stages of pluripotency. Here we report that BMP4 drives primed to naive transition or PNT by reprogramming chromatin accessibility. ATAC-seq reveals that a short pulse of BMP4 triggers EpiSCs to close 26409 and open 6428 loci to reach an intermediate state that continue to open 18744 and close 7042 loci under 2iL until reaching a naive state, following with a dramatic reactivation of the silenced X chromosome. Among loci opened by BMP4 are those encoding Id1, Tfap2c/2a and Zbtb7b that synergistically drive PNT without BMP4. Tfap2c-/- ESCs or EpiSCs self-renew normally, while the former capable of differentiating to the latter but the latter fails to undergo PNT, a defect rescuable by exogenous Tfap2c. Our results link BMP4 to PNT through a binary logic of chromatin closing and opening, revealing the intrinsic power of extracellular factors to reorganize nuclear architecture in development.

Project description:Here we propose a set of molecular criteria for evaluating the naive human pluripotent state. We show by RNA-seq that transcription of transposable elements provides a sensitive measure of the concordance between pluripotent stem cells and early human development. RNA-seq of 4 naive ES samples in 4i/LA, 3 naive ES samples in 5i/LA, 2 transgene-dependant naive ES cell samples, and 5 primed ES cell samples (in hESM)

Four chromatin marks H3K4me1, H3K4me3, H3K27ac and H3K27me3 were measured from 3 cell lines: C1 and WIBR3 (naM-CM-/ve and conventional/primed stem cells), and BGO1 (only naM-CM-/ve stem cells).

Project description:We performed mRNA-seq and small RNA-seq on the newly derived ELF human naïve pluripotent stem cell line and compared with the existing H1 human primed line. Expression analysis revealed that mitochondria oxidative phosphorylation and fatty acid beta-oxidaton is up-regulated in naive state while fatty acid synthesis is up-regulated in primed state. Small RNA-seq revealed consistent expression changes in microRNAs that target key fatty acid beta-oxidation and synthesis genes. Integration with metabolomics data revealed consistent changes in the expression of NNMT (higher in naive state) and IDO1 (higher in primed state) and in the concentration of corresponding metabolic substrates and products. As a regulator of S-Adenosyl methionine (SAM) level, NNMT is proposed as a candidate regulator of epigenetic states. ChIP-seq analysis releaved that naive lines have lower H3K27me3 marks in developmental genes. Inhibition of STAT3, a known regulator of NNMT, reduces NNMT expression level and decreases overall H3K27me3 marks around transcriptional start sites. In particular, STAT3 inhibitor treatment increased H3K27me3 marks in 313 genes that also have higher H3K27me3 marks in primed state than naive state. These 313 genes are enriched with developmental functions, and include several WNT pathway genes. In summary, integrative analysis of RNA-seq, ChIP-seq and metabolomics data revealed key metabolic differences between naive and primed pluripotency and identified NNMT as a key regulator of epigeneitc state.
