RNA-seq analysis of global RNA levels at 4 stages of directed cardiac differentiation of mouse embryonic stem cells

ABSTRACT: We interrogated the transcriptome using RNA-seq at several stages of an mouse embryonic stem cell to cardiomyocyte directed differentiation protocol. These four stages represent timepoints when differentiating cultures are enriched for embryonic stem cells (ESC), mesodermal cells (MES), cardiac precursors (CP), or cardiomyocytes (CM) respectively. This study revealed many dynamic patterns of mRNAs and long non-coding RNAs (lncRNAs) and identified groups of genes with similar expression patterns during differentiation.

ChIP-seq analysis of histone modifications and RNA polymerase II at 4 stages of directed cardiac differentiation of mouse embryonic stem cells

Project description:We interrogated the genome-wide occupancy of histone modifications and RNA polymerase II at several stages of an mouse embryonic stem cell to cardiomyocyte directed differentiation protocol. These four stages represent timepoints when differentiating cultures are enriched for embryonic stem cells (ESC), mesodermal cells (MES), cardiac precursors (CP), or cardiomyocytes (CM) respectively. This study revealed many dynamic patterns of histone modifications during differentiation that are coordinated with stage-specific gene expression including a novel preactivation chromatin pattern found at genes associated with cardiac function. In addition, this study identified distal enhancer elements and enriched transcription factor motifs within enhancer regions for each stage of differentiation, which were used to predict novel transcription regulatory networks.

Unravelling the chromatin landscape and enhancer logic mediating spatiotemporal patterning of early cardiovascular progenitors [ChIP-seq]

Project description:The mammalian heart arises from various populations of Mesp1-expressing cardiovascular progenitors (CPs) that are specified during the early stages of gastrulation. Mesp1 acts as a master regulator of CP specification and differentiation. However, how Mesp1 regulates the chromatin landscape of nascent mesodermal cells to define the temporal and spatial patterning of the distinct populations of CP remains unknown. Here, by combining ChIP-seq, RNA-seq and ATAC-seq during mouse pluripotent stem cell differentiation, we defined the temporal remodelling of the chromatin landscape mediated by Mesp1. We identified different enhancers that are temporally regulated to erase the pluripotent state and specify the pools of CPs that mediate heart development. We found that Mesp1 acts as a pioneer transcription factor (TF) and identified Zic TFs as essential cofactors that regulate Mesp1 pioneer activity at key mesodermal enhancers, thereby regulating the chromatin remodelling and gene expression associated with the specification of the different populations of CPs in vivo. Our study identifies the dynamics of the chromatin landscape and enhancer remodelling associated with temporal patterning of early mesodermal cells into the distinct populations of CPs that mediate heart development.

Genome-wide gene expression analysis of undifferentiated mouse embryonic stem cells (mES), neonatal mouse cardiomyocytes (CMp) and adult mouse cardiomyocytes (CMa)

Project description:Genome-wide gene expression analysis at different stages of cardiomyocyte differentiation (undifferentiated mouse embryonic stem cells, neonatal mouse cardiomyocytes and adult mouse cardiomyocytes). Results provide important information on the differential expressed genes between undifferentiated mouse embrionic stem cells (mES) and mouse cardiomyocytes (CM) and also between cardiomyocytes from neonatal (CMp) and adult stages (CMa). This dataset allowed us to compare the expression profile of mES, CMp and CMa with the epigenetic profile of histone methylation generated with ChIP-seq experiments. Total RNA was obtained from biological triplicate of undifferentiated mouse embryonic stem cells (mES), neonatal mouse cardiomyocytes (CMp) and adult mouse cardiomyocytes (CMa)

Scl specifies hemogenic endothelium and inhibits cardiogenesis via primed enhancers [ChIP-seq]

Project description:Scl/Tal1 confers hemogenic competence and prevents cardiomyogenesis in embryonic endothelium. Here we show that Scl both directly activates a broad gene regulatory network required for hematopoietic stem/progenitor cell (HS/PC) development, and represses transcriptional regulators required for cardiogenesis. Cardiac repression occurs during a short developmental window through Scl binding to distant cardiac enhancers that harbor H3K4me1 at this stage. Scl binding to hematopoietic regulators extends throughout HS/PC and erythroid development and spreads from distant enhancers to promoters. Surprisingly, Scl complex partners Gata 1 and 2 are dispensable for hematopoietic versus cardiac specification and Scl binding to the majority of its target genes. Nevertheless, Gata factors co-operate with Scl to activate selected transcription factors to facilitate HS/PC emergence from hemogenic endothelium. These results uncover a dual function for Scl in dictating hematopoietic versus cardiac fate choice and suggest a mechanism by which lineage-specific bHLH factors direct the divergence of competing fates. ChIP-seq with Scl, Hand1, Lsd1, Ezh2, H3K4me1 and H3K27ac in different cell types with mesodermal origin.

Dynamic changes of mRNA expression during development of human embryonic stem cells derived cardiomyocytes

Project description:To dissect complex regulatory mechanisms on cardiac development, we performed the time-series gene expression experiments of human embryonic stem cells (ESCs) differentiated to cardiomyocytes (CMs). The RNA-sequencing at 4 stages of human to CM maturation, representing timepoints with days 15, 30, 45 and 60 of ESC-CMs. The early CMs from differentiation days (D) 0-15 are commonly considered to be immature and embryonic-like. We define late CMs after D15. During this phase, the cells stop dividing and undergo some degree of maturation. This study established distinct dynamic expression patterns of mRNAs/genes and identified several subsets of up- or down-regulated genes with similar expression patterns during CM differentiation and maturation.
