Gene expression profiles of mouse ESC cardiomyocyte-specific differentiation

ABSTRACT: The differentiation to cardiomyocytes is a prerequisite and an important part of heart development. A good understanding of the complicated cardiomyocyte differentiation process benefits cardiogenesis study. Embryonic stem cells (ESCs), cell lines with infinite ability to proliferate and to be differentiated into all cell types of the adult body, are important research tools for investigation of differentiation and meanwhile good models for developmental research. In the current study, genome-wide gene expression of ESCs is profiled through high throughput platform during cardiomyocyte-specific differentiation and maturation. Gene expression patterns of undifferentiated ESCs and ESC-derived cardiomyocytes provide a global overview of genes involved in cardiomyocyte-specific differentiation, whereas marker gene expression profiles of both ESC-related genes and cardiac-specific genes presented the expression pattern shift during differentiation in a pure ESC-derived cardiomyocyte cell culture system.

Transgenic mouse ESC clone with M-NM-1-MHCM-bM-^@M-^SPacM-bM-^@M-^SIRESM-bM-^@M-^SEGFP vector containing the EGFP gene and the PuromycinR (Pac) cassette under control of the cardiac M-NM-1-myosin heavy chain (M-NM-1-MHC) promoter was cultured and induced into differentiation. Puromycin was applied after differentiation start to enable cardiomyocyte-specific differentiation. Cells were harvested at 4 time points after differentiation start (day0, day12, day19 and day26). Two biological replicates were taken for every time point.

Population RNA-seq of human ESC-derived cardiac derivatives

Project description:In vitro cardiac differentiation of human ESCs recapitulates in vivo embryonic heart development, and thus, serves as an excellent tool to investigate human cardiac development. Identification of molecular signatures during cardiac differentiation of human ESCs is instrumental for advancing our understanding of human cardiogenesis. We, as well as others have improved cardiac differentiation protocols significantly in recent years; however, detailed molecular mechanisms involved in cardiac lineage commitment have not yet been clearly defined. Based on this, we tried to identify the cellular hierarchies and molecular signatures of each of the in vitro human ESC-differentiating cardiac cell lineages through the well-established cardiac differentiatio protocol by Wnt signaling modulation and the FACS-sorted population RNA-seq analyses.

The H2Bub1-deposition complex is required for human and mouse cardiogenesis (RNA-Seq)

Project description:De novo variants affecting monoubiquitination of histone H2B (H2Bub1) are enriched in human congenital heart disease. H2Bub1 is required in stem cell differentiation, cilia function, post-natal cardiomyocyte maturation, and transcriptional elongation. However, how H2Bub1 affects cardiogenesis is unknown. We show that the H2Bub1-deposition complex (RNF20-RNF40-UBE2B) is required for mouse cardiogenesis and for differentiation of human iPSCs into cardiomyocytes. Mice with cardiac-specific Rnf20 deletion are embryonic lethal and have abnormal myocardium. We then analyzed H2Bub1 marks during differentiation of human iPSCs into cardiomyocytes. H2Bub1 is erased from most genes at transition from cardiac mesoderm to cardiac progenitor cells, but is preserved on a subset of long cardiac-specific genes. When H2Bub1 is reduced in iPSC-cardiomyocytes, long cardiac-specific genes have fewer full-length transcripts. This correlates with H2Bub1 accumulation near the center of these genes. H2Bub1 accumulation near the center of tissue-specific genes was also observed in embryonic fibroblasts and fetal osteoblasts. In summary, we show that normal H2Bub1 distribution is required for cardiogenesis and cardiomyocyte differentiation, and point to H2Bub1 regulating tissue-specific gene expression by increasing the amount of full-length transcripts.

GATA factors efficiently direct cardiac fate from ESCs

Project description:Gata5 efficiently promotes cardiomyocyte fate from murine ESCs.By removing serum from the culture conditions, GATA4 and GATA6 are each also able to efficiently promote cardiogenesis in ESC derivatives, with some distinctions. Thus, GATA factors can function in ESC derivatives upstream of other cardiac transcription factors to direct specification of progenitors with cardiac potential. We used microarray to compared the global gene expression of Gata5-induced cardiac cells with other growth factor directed ESC-derived cardiac cells iGata5 ESCs were induced with doxycycline at day 4 and harvested at day16 for RNA extraction and hybridization on Affymetrix microarrays.

Parthenogenetic stem cells for tissue-engineered heart repair

Project description:Uniparental parthenotes are considered an unwanted byproduct of in vitro fertilization. In utero parthenote development is severely compromised by defective organogenesis and in particular by defective cardiogenesis. Although developmentally compromised, apparently pluripotent stem cells can be derived from parthenogenetic blastocysts. Here we hypothesized that nonembryonic parthenogenetic stem cells (PSCs) can be directed toward the cardiac lineage and applied to tissue-engineered heart repair. We first confirmed similar fundamental properties in murine PSCs and embryonic stem cells (ESCs), despite notable differences in genetic (allelic variability) and epigenetic (differential imprinting) characteristics. Haploidentity of major histocompatibility complexes (MHCs) in PSCs is particularly attractive for allogeneic cell-based therapies. Accordingly, we confirmed acceptance of PSCs in MHC-matched allotransplantation. Cardiomyocyte derivation from PSCs and ESCs was equally effective. The use of cardiomyocyte-restricted GFP enabled cell sorting and documentation of advanced structural and functional maturation in vitro and in vivo. This included seamless electrical integration of PSC-derived cardiomyocytes into recipient myocardium. Finally, we enriched cardiomyocytes to facilitate engineering of force-generating myocardium and demonstrated the utility of this technique in enhancing regional myocardial function after myocardial infarction. Collectively, our data demonstrate pluripotency, with unrestricted cardiogenicity in PSCs, and introduce this unique cell type as an attractive source for tissue-engineered heart repair. 8 samples in total. Parthenogenetic stem cells (PSC): - PSC_1 - PSC_2 - PSC_3 Embryoid body (EB) assays of parthenogenetic stem cells: - EB_PSC_1 - EB_PSC_2 Embryonic stem cells (ESC): - ESC_1 - ESC_2 - ESC_3

KDM6 Inhibition induces DNA Damage Response (DDR) during ESC Differentiation but not during self-renewal.

Project description:The discovery of the first histone demethylase in 2004 (LSD1/KDM1) opened new avenues for the understanding of how histone methylation impacts cellular functions. A great number of histone demethylases have been identified since, which are potentially linked to gene regulation as well as to stem cell self-renewal and differentiation. KDM6A/UTY and KDM6B/JMJD3 are both H3K27me3/2-specific histone demethylases, which are known to play a central role in regulation of posterior development, by regulating HOX gene expression. So far nothing is known about the role of histone lysine demethylases (KDMs) during early hematopoiesis. We are studying the role of KDM6A and KDM6B on self-renewal, global gene expression and on local and global chromatin states in embryonic stem cells (ESCs) and during differentiation. In order to completely abrogate KDM6 demethylase activity in ESCs we employed a specific inhibitor (GSK-J4, Kruidenier et al. 2012). Treatment of ESCs with GSK-J4 had no effect on viability and proliferation . However, ESC differentiation in the presence of GSK-J4 was completely abrogated. In conclusion we show that ESC differentiation is completely blockend in the absence of any H3K27 demethylase activity. We used microarrays to detail the global gene expression program of genes which are differentially expressed during the early differentiation of ESC derived embryoid bodies (EBs) in the presence of GSK-J4 (KDM6 Inhibitor). ESCs (R1) have been cultured and differentiated in the presence of GSK-J4 a KDM6 specific inhibitor.

Dynamic lncRNA expression pattern during ESC-derived cardiac differentiation

Project description:Long noncoding RNAs (lncRNAs) have emerged as crucial regulators of gene expression during embryonic stem cell (ESC) self-renewal and differentiation. Here, we systemically analyzed the differentially regulated lncRNAs during ESC-derived cardiomyocyte (CM) differentiation. We established a perspicuous profile of lncRNA expression at four critical developmental stages and found that the differentially expressed lncRNAs were grouped into six distinct clusters. The cluster with specific expression in ESC enriches the largest number of lncRNAs. Investigation of lncRNA-protein interaction network revealed that they are not only controlled by classic key transcription factors, but also modulated by epigenetic and epitranscriptomic factors including N6-methyladenosine (m6A) effector machineries.
