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

ABSTRACT: 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.

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 of human breast tumor samples with exhausted and non-exhausted immune environments

Project description:Fresh human breast tumor tissue was dissociated into single cells and viably frozen. Patient samples were annotated as having an ""exhausted"" or ""non-exhausted"" immune environment based on CyTOF characterization of T cell phenotypes (Wagner et al, Cell 2019). 14 samples (7 exhausted, 7 non-exhausted) were selected for scRNA-seq (without prior cell type enrichment) with the goal to compare the two immune environment types and to comprehensively characterize exhaustion-associated features of the tumor microenvironment.

Single-cell RNAseq of HA-specific CD8 T cells isolated from the hypothalamus and the spleen of mice expressing the model antigen HA in orexinergic neurons

Project description:We previously generated the Orex-HA mouse model in which orexin-producing neurons residing in the hypothalamus selectively expressed a model self-antigen, namely hemagglutinin (HA) from the H1N1 influenza virus. In this model the adoptive transfer of in vitro activated HA-specific CD8 T cells leads to the specific loss of orexinergic neurons located in the hypothalamus. To assess the phenotype and investigate the pathogenic mechanisms and the potential tissue-resident properties of autoreactive (HA-specific) CD8 T cells infiltrating the hypothalamus of Orex-HA mice , we performed a single-cell transcriptomic analysis (scRNA-seq) of HA-specific CD8+ T cells isolated from the hypothalamus and the spleen at day 30 after T cell transfer in Orex-HA mice.

scRNA-seq of kidney marrow cells from Gata2b deficient and wild type zebrafish

Project description:GATA2 is a pivotal hematopoietic transcription factor required for generation and maintenance of hematopoietic stem cells (HSCs). Due to early embryonic lethality of Gata2 deficiency in mice, its role during adult hematopoiesis is incompletely understood. In zebrafish, mammalian functions of Gata2 are split between two orthologues: Gata2a and Gata2b. Previous studies have shown that Gata2b is prominently expressed in hematopoietic stem and progenitor cells (HSPCs), whereas Gata2a is mainly expressed in the vasculature. We found that Gata2b deficient zebrafish have a reduction in embryonic definitive HSPC numbers and have impaired myeloid lineage differentiation, but are viable. This allowed us to study the role of Gata2b in adult hematopoiesis. To assess the impact of Gata2b deficiency on the transcriptional profile of HSPCs and differentiated cells, we sorted the entire progenitor and HSPC population including the lymphoid population from kidney marrow (KM) of WT and germline Gata2b deficient zebrafish based on scatter profiles and processed for single-cell RNA sequencing. To enrich the scarce HSC population, we used pooled KM from two WT and Gata2b deficient Tg(CD41:GFP) zebrafish per sample and included all CD41:GFPlow expressing cells present in the kidney marrow pool as these cells were shown to contain transplantable HSCs.

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

Project description: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.

scRNA-seq of hPSC-derived human intestinal organoids with endogenous vascular endothelial cells

Project description:The development of human pluripotent stem cell (hPSC)- derived small intestinal organoids (HIOs) has led to an improved understanding of human intestinal development and physiology. HIOs generated using directed differentiation lack some cellular populations found in the native organ, including vasculature. We performed single cell RNA sequencing (scRNA-seq) on approximately 13,000 cells at various timepoints (0, 3, 7, and 14 days) across HIO in vitro development and observed a transient population of endothelial-like cells (ECs) present within HIOs early during differentiation. Our data demonstrate that EC-like cells fail to be robustly maintained in long term culture. Here, we have developed a new directed differentiation approach to enhance co-differentiation and maintenance of ECs within HIOs, leading to the development of vascularized HIOs (vHIOs). scRNAseq was used to compare vHIOs to control HIOs after 59d months in culture.
