ABSTRACT: Biparental, androgenetic and parthenogenetic human embryonic stem cell lines were differentiated into granulosa-like cells for transcriptome comparison
Project description:Biparental human embryonic stem cell lines were differentiated into granulosa-like cells and sorted for AMHR2+ granulosa marker. Parthenogenetic human embryonic stem cell lines were differentiated into granulosa-like cells with or without the presence of igf2.
Project description:The purpose of this study was to characterise iPSC-derived human intestinal epithelial organoids (iPSCo) by comparing these cultures with primary purified intestinal epithelial cells (IEC). Intestinal epithelial organoid (IEO) cultures were derived from at least three different lines of iPSCs, RNA was extracted and gene expression was profiled using RNA-sequencing. We compared these profiles with datasets we have previously derived from purified IEC from mature terminal ileum (TI) and sigmoid colon (SC) as well as human fetal proximal gut (FPG) and fetal distal gut (FDG).
Project description:Parallel transcription profiling of cardiomyocyte clusters derived from human embryonic stem cells. Both mRNA (this experiment) and miRNA (see E-MEXP-2655) transcription are measured and fetal and adult heart tissues are included as controls. This experiment was updated on 7th July 2011 to fix incorrect AH6 and FH3 files.

Project description:RNAseq was carried out to compare global transcriptional profiles of human pluripotent H9 stem cells with tissues derived from these cells through directed differentiation, including endoderm and human intestinal organoids.
Project description:The transcription factor BRACHYURY (T, BRA) is one of the first markers of gastrulation and lineage specification in mammals. Despite its wide use and importance in stem cell and developmental biology, its genomic targets are largely unknown. Here, we used differentiated human embryonic stem cells to study the role of BRA in Bmp4-induced mesoderm and Activin-induced endoderm progenitors by ChIP-seq. We show that BRA has distinct genome-wide binding landscapes in these two populations. Our data illuminate the function of BRA in the context of human embryonic development and show that the regulatory role of BRA is context-dependent. ChIP-seq of BRACHYURY (T, BRA) in two cell types: endoderm and mesoderm progenitors derived from human embryonic stem cells after 36 hours of growth in chemically-defined media (described in Bernardo et al., Cell Stem Cell, 2011, 9:144-155). Input DNA samples are included as a control.
Project description:Stable Pax6 and Luciferase knockdown human embryonic stem cell lines (H9) were made through lentiviral infection. Two different Pax6 RNAi lines and two Luciferase RNAi lines were then differentiated to neuroectoderm cells for 6 days. mRNA pooled from these two individual lines were then subjected to gene expression profiling analysis using affymetrix U133 plus 2.0 array.
Project description:Transcriptional profiling of H9 hESCs (wild type and BRACHYURY shRNA knockdown) differentiated for 36h or 72h in chemically-defined culture media supplemented with FGF2, LY294002 and either BMP4 or ActivinA.
Project description:Whole-genome single-base resolution methylcytosine map reveals profound changes that occur after Lsh deletion during embryonic development in primary WT and Lsh-/- MEFs. Lsh deletion leads to widespread decreases of CG methylation level at uniquely mapped genomic regions compared to wild type, including TSSs at protein-coding genes, and non-coding RNA genes. MethylC-Seq from Mus musculus primary MEFs.
Project description:Recently, various groups managed to isolate naïve human embryonic stem cell (hESC) state in vitro has come into acceptance. However, a thorough epigenetic characterization of this human ground state, defined as a state without any epigenetic restrictions, and how that compares to mouse is currently lacking. Also, the epigenomic remodeling required to obtain the ground state, and the important transient processes occurring during the remodeling, have remained elusive in human. Here, we address these issues by using an untargeted mass spectrometry-based (MS) approach to profile the histone epigenome in a time-resolved experimental design. Special care was given to defining the naïve hESC state that was reached over 12 passages (P12, 37 days) in feeder-free conditions in this study. We found that conversion is a multi-staged process with a prominent cellular disturbance after stimulation (P3), an increase in cell proliferation between P3 and P6 and a naïve cell state stabilizing between P9 and P12. In total, 20 different histone post-translational modifications (hPTMs) changed significantly over time from primed to naïve hESCs. Most notably, H3K27me3 is the most prominently increasing hPTM in naïve hESCs, in line with what we recently described in mouse. Essentially, we present a first roadmap of the changing human histone epigenome from primed to naïve state and emphasize that the overlap with mouse hints at a conserved Mammalian epigenetic signature of the ground state.
