Single cell RNA sequencing of human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes with or without hiPSC-derived endothelial cells

ABSTRACT: We cultured differentiated hiPSC-derived cardiomyocytes either alone or in co-culture with hiPSC-derived endothelial cells to evaluate potential genes that might facilitate endothelial cell-mediated cardiomyocyte maturation.

miRNA expression profiling of differentiating human-induced pluripotent stem cell (hiPSC)-derived cardiomyocytes

Project description:To gain insight into the molecular regulation of human heart development, a detailed comparison of the mRNA and miRNA transcriptomes across differentiating human-induced pluripotent stem cell (hiPSC)–derived cardiomyocytes and biopsies from fetal, adult, and hypertensive human hearts was performed. Gene ontology analysis of the mRNA expression levels of the hiPSCs differentiating into cardiomyocytes revealed 3 distinct groups of genes: pluripotent specific, transitional cardiac specification, and mature cardiomyocyte specific. Hierarchical clustering of the mRNA data revealed that the transcriptome of hiPSC cardiomyocytes largely stabilizes 20 days after initiation of differentiation. Nevertheless, analysis of cells continuously cultured for 120 days indicated that the cardiomyocytes continued to mature toward a more adult-like gene expression pattern. Analysis of cardiomyocyte-specific miRNAs (miR-1, miR-133a/b, and miR-208a/b) revealed a miRNA pattern indicative of stem cell to cardiomyocyte specification. A biostatistitical approach integrated the miRNA and mRNA expression profiles revealing a cardiomyocyte differentiation miRNA network and identified putative mRNAs targeted by multiple miRNAs. Together, these data reveal the miRNA network in human heart development and support the notion that overlapping miRNA networks re-enforce transcriptional control during developmental specification. miRNA expression profiling of differentiating human-induced pluripotent stem cell (hiPSC)–derived cardiomyocytes (days 0-120)

Contractile work contributes to maturation of energy metabolism in hiPSC-derived cardiomyocytes

Project description:Energy metabolism is a key aspect of cardiomyocyte biology. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) are a promising tool for biomedical application, but they are immature and have not undergone metabolic shift related to early postnatal development. Cultivation of hiPSC-CM in 3D engineered heart tissue (EHT) format leads to morphological maturation. This study compared the mitochondrial and metabolic state of hiPSC-CM in standard 2D culture and the EHT format and determined the influence of contractile activity. HiPSC-CM in EHTs showed ~2-fold higher number of mitochondria (electron microscopy), mitochondrial mass (mitotracker), DNA (Mt-ND1, Mt-ND2), and protein abundance (proteome) than in 2D culture. While hiPSC-CM exhibited the principal ability to use glucose, lactate and fatty acids as energy substrates irrespective of culture format, hiPSC-CM in 3D performed more oxidation of glucose, lactate and fatty acid, and less anaerobic glycolysis. The increase in mitochondrial mass and DNA in 3D was diminished by pharmacological inhibition of contractile force, suggesting that contractile work participates in mitochondrial development hiPSC-CM. In conclusion, contractile work in the EHT format contributes to metabolic maturation of hiPSC-CM.

RNA-Seq transcriptome profiling of human iPS cell-derived cardiomyocytes (hiPSC-CMs) following overexpression (OE) of estrogen-related receptor gamma (ERRg)

Project description:Transcriptional regulatory circuits that drive cardiomyocyte maturation are poorly understood. Human iPS cell-derived cardiomyocytes (hiPSC-CMs) have been shown to have fetal cardiomyocyte features in terms of metabolic gene expression profiles. Here we found that in hiPSC-CMs, overexpression of estrogen-related receptor gamma (ERRg) is sufficient to drive cardiomyocyte metabolic maturation programs including the induction of a number of oxidative mitochondrial metabolic genes.

Effect of RPS3 Serine 149 mutation on gene expression in hiPSC-derived cardiomyocytes during Ang II administration

Project description:Angiotensin II (Ang II) treatment contributes to hypertrophic growth and mitochondrial dysfunction in hiPSC-derived cardiomyocytes. Here, we report enhanced RPS3 phosphorylation at serine 149 in nuclear compartment and abnormal mitochondrial biogenesis during Ang II incubation. Furthermore, RPS3 S149 mutation attenuated Ang II induced cardiomyocyte hypertrophy and improved mitochondrial biogenesis and dysfunction. Mechanistically, RPS3 Ser149 mutation promoted mitochondrial RNA stabilization and blunt Ang II induced mitochodnrial RNA alternative splicing for degradation, by which RPS3 dephosphorylation restored mitochondrial complex assembly in cardiomyocytes.

Thyroid Hormone effects on hiPSC-derived cardiomyocytes (hiPSC-CM). Identification of target genes and pathways by RNA-Seq analysis

Project description:QT prolongation represents a dangerous and potentially life-threatening electrical event affecting the heart. Thyroid hormones (THs) are critical for cardiac development and heart function. However, little is known about THs influence on ventricular repolarization and controversial effects on QT prolongation are reported. Aim of this study was to characterize the direct effects of THs on the cardiac repolarization of human Induced Pluripotent Stem Cell derived cardiomyocytes (hiPSC-CM). RNA Seq analysis of hiPSC-CM treated with Thyroid Hormone T3 indicates significant deregulation in genes involved in cardiac pathways, in particular in ion homeostasis.
