Single-cell RNA-seq on enriched cardiac fibroblasts from the healthy, sham or MI hearts of Hif-1a conditional knockout or heterozygous mice

ABSTRACT: In this project we explore the role of the master hypoxia regulator, Hypoxia inducible factor-1alpha (Hif-1a), in governing cardiac fibroblast (CF) function in homeostasis and following an acute ischaemic injury - myocardial infarction (MI). CF-specific Hif-1a conditional knockout (cKO) mice were generated by breeding Pdgfra-merCremer (PdgfraMCM/+) Cre recombinase driver mice with Hif-1a-floxed mice (Hif-1aflox/). In Hif-1afl/-; PdgfraMCM/+ progeny, Hif-1a could be conditionally deleted in adult CFs by tamoxifen (tam) administration. We also introduced a Cre-dependent R26tdTomato reporter allele allowing marking of Pdgfra+ CFs and their progeny. In this experiment, we first performed single-cell RNA sequencing (scRNA-seq) on tdTomato+ cells from the hearts of healthy cKO or heterozygous (HET) adult, male mice using the 10x Genomics Chromium system. We also performed scRNA-seq on tdTomato+/CD31-/CD45- cells from the hearts of cKO or HET mice at day-3 post-sham or -MI surgery.

Single-cell RNA-seq of mouse cardiac interstitial cells 3 & 7 days after sham or myocardial infarction injury

Project description:The aims of the experiment were to profile the cell types in the adult mouse cardiac interstitium (non-myocyte cells) and how they respond to myocardial infarction injury. Adult, male, Pdgfra +/GFP mice were subject to either a myocardial infarction or sham injury, with cells isolated from cardiac ventricles 3 or 7 days following surgery. We obtained scRNA-seq profiles of two cell fractions: total interstitial (non-myocyte) cell population (TIP) and FACS-sorted GFP+/Cd31- cells (GFP).

Single cell RNA-seq profiling of T cells isolated from MC38 mouse tumors

Project description:We investigate the single-cell landscape of the inflammatory mouse tumor model MC38, a C57BL/6 tumor cell line derived from colon adenocarcinoma. MC38 (diluted in HBSS and matrigel) was inoculated in the right unilateral flank (in the border of positions B2 and B3) of C57BL/6 mice (ref Study 16-3384 AV). Tumors were taken one day after group-out (average 150-250 mm3 at day 0), approximately 14-19 days. Tissues were dissociated and flow sorted accordingly to obtain the following groups for 10x Chromium 5' Gene Expression Profiling. Our results indicate that the degree of clonal expansion is correlated with expression of T cell exhaustion markers, and that T cells with strong exhaustion phenotype also express high levels of activation markers, such as interferon gamma.

Joint single-cell/single-nucleus RNA-seq on hearts from healthy or HFpEF mice

Project description:In this project we explore the cellular heterogeneity of a mouse model of heart failure with preserved ejection fraction (HFpEF) involving a two-hit model of feeding a high fat diet (HFD) along with L-NAME administration. Healthy adult male mice (C57BL/6J inbred) were fed either a normal chow diet or HFD/L-NAME for 10 weeks or 15 weeks before performing sequencing experiments. Both cardiomyocytes (CMs) and total interstitial population (TIP) were captured using a protocol to jointly capture and sequence single-nuclei (for cardiomyocytes) and single-cells (for TIP) using the 10x Genomics Chromium system.

Single-cell RNA-seq (10x Chromium) of FACS-sorted drl:H2B-Dendra2, etv2:Kaede, fli1:DsRed, and tp1:eGFP transgenic zebrafish embryos

Project description:Development of the dorsal aorta is a key step in the establishment of the adult blood-forming system, since hematopoietic stem and progenitor cells (HSPCs) arise from ventral aortic endothelium in all vertebrate animals studied. Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here, we profile the transcriptome of the earliest detectable endothelial cells (ECs) during zebrafish embryogenesis to demonstrate that tissue-specific EC programs initiate much earlier than previously appreciated, by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite-derived endothelial cells (SDECs) that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish, where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential, they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus, at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs, hemogenic ECs, and SDECs. Taken together, our findings indicate that the distinct spatial origins of endothelial precursors dictate different cellular potentials within the developing dorsal aorta.

Single cell RNA-seq and VDJ-seq of B cells from sheep red blood cells-primed WT and Stch cKO mice

Project description:Once activated, B cells produce the antibodies needed to fight against infection. B cells are necessary for adaptive or specific immunity, which focuses on the destruction of foreign invaders that have gotten past the bodies initial defenses. Heat shock protein family is a group of highly conserved molecular chaperones with important functions in protein folding such as antibody and in signal transduction. Stch (Heat shock 70 kDa protein 13) is a member of the heat shock protein 70 family and is found associated with microsomes. Members of this protein family play a role in the processing of cytosolic and secretory proteins. To explore the role of Stch in B-cell activation and antibody production, we evaluated the transcriptional events and the role of stch pathway on the activation and antibody production of B cells by single cell RNAseq. Splenic lymphocytes were isolated from 7-9-week-old female Stchf/f wildtype (WT) mice and B-cell specific Stch knocked-out (CD19creStchf/f) mice (3 mice/group) using Ficoll (Ficoll-Paque Plus, GE Healthcre). B cells were sorted using B220 microbeads (Cat No. 130-049-501, Miltenyi Biotec, Germany). Their transcriptomes were captured using a 10x chromium system.

Stromal evolution of cancer-associated fibroblasts in PDAC GEMMs

Project description:With the advent of cancer immunotherapy, intense investigation has been focused on tumor-infiltrating immune cells. With only a fraction of patients responding to these new therapies, a better understanding of all elements of the tumor microenvironment (TME) that may influence therapeutic outcome is needed. Stromal elements of the TME, chiefly fibroblasts, have emerged as potential contributors to tumor progression and most recently resistance to immunotherapy, but their precise composition and clinical relevance remain incompletely understood. Here we use single-cell transcriptomics to chart the fibroblastic landscape during pancreatic ductal adenocarcinoma (PDAC) progression in animal models, identifying two healthy tissue fibroblast subsets that co-evolve along individual trajectories into four subsets of carcinoma-associated fibroblasts (CAFs).

Single-cell RNA-seq (10x Chromium V3) of zebrafish csf1ra and csf1rb mutant whole kidney marrows

Project description:Macrophage colony-stimulating factor receptor (M-CSFR/CSF1R) signaling is crucial for the differentiation, proliferation, and survival of myeloid cells. Therapeutic targeting of the CSF1R pathway is a promising strategy in many human diseases, including neurological disorders or cancer. Zebrafish are commonly used for human disease modeling and preclinical therapeutic screening. Therefore, it is necessary to understand the proper function of cytokine signaling in zebrafish to reliably model human-related diseases. Here, we investigate the roles of zebrafish csf1ra and csf1rb in adult myelopoiesis using single-cell RNA sequencing. Our analysis of adult whole kidney marrow (WKM) hematopoietic cells suggests that csf1rb is expressed mainly by blood and myeloid progenitors and that the expression of csf1ra and csf1rb is non-overlapping. We point out differentially expressed genes important in hematopoietic cell differentiation and immune response in selected WKM populations. Our findings could improve the understanding of myeloid cell function and lead to the further study of CSF1R pathway deregulation in disease, mostly in cancerogenesis.
