Project description:We used snRNA-seq to investigate an entire adult mammalian heart of BL6 mice. Whole hearts were harvested from 4 male mice (12 weeks) after cervical dislocation. The hearts were pooled and nuclei isolated using the Nuclei PURE Prep isolation kit (Sigma-Aldrich, Darmstadt, Germany) according to the manufacturer’s protocol. Sequencing was conducted by Genewiz (Leipzig, Germany) on the 10xGenomics system. Single nuclei were captured in droplet emulsions and snRNA-seq libraries were constructed as per the 10x Genomics protocol using GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. RNA was controlled for sufficient quality on an Agilent 2100 Bioanalyzer system and quantified using a Qubit Fluorometer.

Project description:We report RNA-seq of single nuclei isolated from the adult C57BL/6 male mouse Hippocampus region. Majority of the nuclei were isolated from 12 weeks old mice (4 different animal), with an additional set of nuclei from 3 months and 2 years old animals. In addition a set of GFP labeled nuclei driven by a VGAT promoter . Microdissections of dentate gyrus, CA1 and CA2/3 regions of the Hippocampus were placed into ice-cold RNA-later for fixation and stored at 4âc overnight, then stored in -80âc. Nuclei were isolated by sucrose gradient centrifugation and kept on ice until sorting using Fluorescence Activated Cell Sorting (FACS) into 96 well plates containing RNA lysis buffer. Single nucleus RNA was first purified then derived cDNA libraries were generated following a modified Smart-seq2 protocol. For VGAT nuclei: high titer AAV1/2 of pAAV-EF1a-DIO-EYFP-KASH-WPRE-hGH-polyA was injected into dorsal and/or ventral Hippocampus, animals were sacrificed two weeks after injections, and GFP labeled nuclei were sorted into plates and processed as described above.

Project description:We used snRNA-seq to investigate for the first time an entire adult mammalian heart. To avoid potential aberrations due to inbreeding, we relied on an outbred mice strain (Fzt:DU) (Dietl, G.; Langhammer, M.; Renne, U. Model simulations for genetic random drift in the outbred strain Fzt:DU. Arch. Anim. Breed. 2004, 47, 595–604). Whole hearts were harvested from 4 male mice (12 weeks) after cervical dislocation. The hearts were pooled and nuclei isolated using the Nuclei PURE Prep isolation kit (Sigma-Aldrich, Darmstadt, Germany) according to the manufacturer’s protocol. Sequencing was conducted by Genewiz (Leipzig, Germany) on the 10xGenomics system. Single nuclei were captured in droplet emulsions and snRNA-seq libraries were constructed as per the 10x Genomics protocol using GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. RNA was controlled for sufficient quality on an Agilent 2100 Bioanalyzer system and quantified using a Qubit Fluorometer.

Project description:We have demonstrated previously that adult cardiomyocytes can dedifferentiate and proliferate when cultured in vitro. To determine if cardiomyocyte dedifferentiation and cell cycling/proliferation happens in vivo, we applied here a novel multi-reporter transgenic mouse model (aMH-CMerCreMer;mT/MG;aMHC-H2BBFP) carrying reporter genes for permanent cardiomyocyte lineage mapping and maturity (dedifferentiation) reporting. With this new model, we deciphered the cellular sources and processes of cardiomyocyte dedifferentiation and proliferation in adult hearts. In this study, we used single-nucleus RNA-sequencing to tackle the challenges in analyzing the highly heterogeneous heart cell populations, and obtained datasets for a large number of cardiac single nuclei (both myocytes and non-myocytes) for control and post-infarct hearts. We identified specific cell populations in the heart using distinct transcriptomic clusters, transgenic reporters for ACM lineage and dedifferentiation, as well as cell cycle markers. The results demonstrated that the dedifferentiation and cell cycle progression of pre-existing CMs was augmented in post-infarct hearts, with a number of signaling pathways and gene sets affected. This is the first study dissecting the transcriptomic profiles and signaling pathways associated with cardiomyocyte dedifferentiation and cycling/proliferation in vivo using unbiased high-throughput single-nucleus RNA-Seq analysis, in junction with novel cell lineage (e.g. cardiomyocyte) and phenotyping (e.g. dedifferentiation) transgenic model systems.

Project description:Re-activating quiescent adult epicardium represents a potential therapeutic approach for human cardiac regeneration. However, the exact molecular differences between inactive adult and active foetal epicardium are not known. Here, we combined foetal and adult human hearts for the first time using single-cell and single-nuclei RNA sequencing, and compared epicardial cells from both stages. We found a migratory fibroblast-like epicardial population only in the foetal heart and foetal epicardium expressed angiogenic gene programs, while the adult epicardium was solely mesothelial and immune-responsive. Furthermore, we predicted that adult hearts may still receive foetal epicardial paracrine communication, including WNT-signalling with endocardium, reinforcing the validity of regenerative strategies that administer or reactivate epicardial cells in situ. Finally, we explained graft efficacy of our human embryonic stem-cell derived epicardium model, by noting its similarity to human foetal epicardium. Overall, our study defines epicardial programs of regenerative angiogenesis absent in adult hearts, contextualises animal studies, and defines epicardial states required for effective human heart regeneration.

Project description:In these experiments, we aimed to investigate the role of cardiomyocyte-specific deletion of the G-quadruplex resolvase Dhx36 in heart development and cardiomyocyte differentiation. To achieve this, we conducted multi-omics analysis using single-nuclei RNA sequencing (RNA-seq) and ATAC sequencing (ATAC-seq) on hearts from postnatal day 7 (PD7) wild-type (WT) and Dhx36 conditional knockout (cKO) mice. Our findings reveal that Dhx36 plays a critical role in the development of the cardiac conduction system (CCS) and in the differentiation of both CCS and working cardiomyocytes
