Identification of Cardiovascular Lineage Descendants at Single Cell Resolution

ABSTRACT: The transcriptional profiles of cardiac cells derived from murine embryos and from mouse embryonic stem cells (mESCs) have primarily been studied within a cell population. However, the characterization of gene expression in these cells at a single cell level may demonstrate unique variations that are not able to be appreciated as a pool. In this study, we aimed to establish a single cell quantitative PCR platform and perform side-by-side comparison between cardiac progenitors cells (CPCs) and cardiomyocytes (CMs) derived from mESC and mouse embryos. We first generated a reference map for cardiovascular single cells through quantifying lineage-defining genes for CPCs, CMs, smooth muscle cells (SMCs), endothelial cells (EDCs), fibroblasts, and mESCs. This panel was then applied against day 10.5 embryonic heart single cells to demonstrate its ability to identify each endocardial cell and chamber-specific CM. In addition, we compared the gene expression profile of embryo- and mESC-derived CPCs and CMs at different developmental stages and showed that mESC-derived CM is phenotypically similar to embryo-derived CM up to the neonatal stage. Furthermore, we show that single cell expression assay coupled with time-lapse microscopy can resolve the identity and the lineage relationships between progenies of single cultured CPC. With this approach, we found differential propensity for mESC-derived CPCs to become SMCs or CMs, whereas single embryo-derived CPC to become either EDCs or CMs. These results demonstrate that multiplex gene expression analysis in single cells is a powerful tool in examining the unique behavior in individual embryo- or mESC-derived cardiac cells.

Cardiomyocyte progenitors generated by direct reprogramming and molecular beacon selection attenuate ventricular remodelling after experimental myocardial infarction

Project description:Both naturally occurring and artificially engineered multipotent cardiac progenitor cells (CPCs) are associated with highly variable cardiomyocyte (CM) differentiation efficiencies, resulting in unpredictable and/or low CM yields. Therefore, CM-committed progenitors may be a more reliable cell product for therapeutic use. Here, we demonstrate that unipotent progenitors are part of the phenotype spectrum arising during direct reprogramming of neonatal cardiac fibroblasts towards CMs using lentiviral transduction of Gata4, Mef2c, Tbx5, and Myocd. Induced CM progenitors (iCMPs) simultaneously express CPC- and CM-specific proteins and can be selected via hairpin oligonucleotide molecular beacons targeting Myh6/7-mRNA–expressing cells. Purified iCMPs can be expanded extensively with preserved phenotype using ascorbic acid and give rise to CM-like cells in differentiation assays. When transplanted into infarcted mouse hearts, iCMPs prevent CM loss, attenuate fibrotic scarring, and preserve ventricular function. Given the clinical failure of conventional cardiac cell therapy using adult stem cells, further translational development of this iCMP approach is warranted.

Comparative Computational RNA Analysis of Cardiac-Derived Progenitor Cells and Their Extracellular Vesicles

Project description:We aimed to examine differences between c-kit+ progenitor cells (CPCs) and CPC-derived extracellular vesicles (EV) RNA content. We isolated CPCs from cardiac biopsies of patients with congenital heart disease using magnetic bead sorting. We expanded CPCs, reduced serum for 24hrs, and collected secreted EVs from conditioned media with sequential ultracentrifugation. We isolate RNA from CPCs and CPC-EVs and sequence total RNA and miRNA. Sequencing was performed in at two different facilities: "E" and "N".

Cardiac differentiation of embryonic stem cells recapitulates embryonic cardiac development.

Project description:Mouse embryonic stem cells can differentiate in vitro into spontaneously contracting cardiomyocytes. The main objective of this study was to investigate cardiogenesis in cultures of differentiating embryonic stem cells (ESCs) and to determine how closely it mimics in vivo cardiac development. We identified and isolated a population of cardiac progenitor cells (CPCs) through the use of a reporter DNA construct that allowed the expression of a selectable marker under the control of the Nkx2.5 enhancer. We proceeded to characterize these CPCs by examining their capacity to differentiate into cardiomyocytes and to proliferate. We then performed a large-scale temporal microarray expression analysis in order to identify genes that are uniquely upregulated or downregulated in the CPC population. We determined that the transcriptional profile of the mESC derived CPCs was consistent with pathways known to be active during embryonic cardiac development. We conclude that in vitro differentiation of mESCs recapitulates the early steps of mouse cardiac development. Keywords: embryonic stem cell, differentiation, cardiac progenitor, cardiogenesis

Chromatin accessibility profiles of early cardiac precursor cells at single cell resolution

Project description:Transcriptional networks governing cardiac precursor cell (CPC) specification are incompletely understood due in part to limitations in distinguishing CPCs from non-cardiac mesoderm in early gastrulation. We leveraged detection of early cardiac lineage transgenes within a granular single cell transcriptomic time course of mouse embryos to identify emerging CPCs and describe their transcriptional profiles. Mesp1, a transiently-expressed mesodermal transcription factor (TF), is canonically described as an early regulator of cardiac specification. However, we observed perdurance of CPC transgene-expressing cells in Mesp1 mutants, albeit mis-localized, prompting us to investigate the scope of Mesp1’s role in CPC emergence and differentiation. Mesp1 mutant CPCs failed to robustly activate markers of cardiomyocyte maturity and critical cardiac TFs, yet they exhibited transcriptional profiles resembling cardiac mesoderm progressing towards cardiomyocyte fates. Single cell chromatin accessibility analysis defined a Mesp1-dependent developmental breakpoint in cardiac lineage progression at a shift from mesendoderm transcriptional networks to those necessary for cardiac patterning and morphogenesis. These results reveal Mesp1-independent aspects of early CPC specification and underscore a Mesp1-dependent regulatory landscape required for progression through cardiogenesis.

A Regulatory Pathway Involving Notch1/β-Catenin/Isl1 Determines Cardiac Progenitor Cell Fate

Project description:The regulation of multipotent cardiac progenitor cell (CPC) expansion and subsequent differentiation into cardiomyocytes, smooth muscle, or endothelial cells is a fundamental aspect of basic cardiovascular biology and cardiac regenerative medicine. However, the mechanisms governing these decisions remain unclear. Here, we show that Wnt/β-Catenin signaling, which promotes expansion of CPCs, is negatively regulated by Notch1-mediated control of phosphorylated β-Catenin accumulation within CPCs, and that Notch1 activity in CPCs is required for their differentiation. Notch1 positively, and β-Catenin negatively, regulated expression of the cardiac transcription factors, Isl1, Myocd and Smyd1. Surprisingly, disruption of Isl1, normally expressed transiently in CPCs prior to their differentiation, resulted in expansion of CPCs in vivo and in an embryonic stem (ES) cell system. Furthermore, Isl1 was required for CPC differentiation into cardiomyocyte and smooth muscle cells, but not endothelial cells. These findings reveal a regulatory network controlling CPC expansion and cell fate that involve unanticipated functions of β-Catenin, Notch1 and Isl1 that may be leveraged for regenerative approaches involving CPCs.
