Genome-wide maps of chromatin state in epiblast stem cells and nodal inhibited ebiblast stem cells

We reported H3K4me3, H3K27ac and H3K27me3 histone modification in EpiSCs and Nodal inhibited EpiSCs(EpiSCS/F). Using ChIP sequencing, we demonstrate that the active modification of H3K4me3 and H3K27ac level are higher in EpiSCS/F, suggesting EpiSCsS/F were in an active chromatin state. Interestingly, H3K27me3, the supressive modification enriched more in EpiSCS/F down regulated genes, suggesting H3K27me3 plays pivital roles in regulating gene expression. Overall design: Examination of 3 different histone modifications in 2 cell types
