Single-cell transcriptomics reveals heterogeneous metabolic profiles in primary human hepatocytes

ABSTRACT: Through scRNA-sequencing of primary human hepatocytes (PHHs), we have identified four subgroups of hepatocytes. A phenotyping 5-probe cocktail (Sanofi-Aventis) has been used to assess their metabolic capacity. Upon cocktail treatment, the characterized four hepatocyte subgroups displayed differential gene expression profiles and exhibited xenobiotic metabolism-related specialization. Intracellular lipid accumulation achieved through loading the cells with free fatty acids (FFA, 2:1 oleic:palmitic acid), differently affected the four subgroups. Moreover, we have shown that intracellular fat accumulation diminishes the drug-related metabolic capacity of hepatocytes.

scRNA-seq of CD45+ cells isolated from lungs of mice carrying KPneo tumors that received FLT3L and αCD40 (DC-therapy) or rat IgG2a isotype control

Project description:Dendritic cells are key player to initiate anti-tumoral response. In this study we aimed to characterize the function of type 1 DCs during priming of CD8 T cell responses against endogenous neoantigens encoded by a KrasG12D/WT; Tp53 (KP) lung cancer model. To enhance the immunostimulatory properties of cDC1, we delivered a combination of Flt3L and aCD40 antibodies. We found that this therapy is sufficient to induce proliferation of neoantigen specific CD8 T cells and restrain growth of lung tumor nodules. scRNA-seq transcriptional profiling of the lung immune infiltrate of tumor-challenged animals with and without DC-therapy was performed to understand the molecular changes induced in DCs subsets and CD8 T cell subsets.

Single cell RNA sequencing of lung dendritic cells in healthy and hyperglycemic mice

Project description:We performed single cell RNAseq to measure gene expression in different subsets of lung dendritic cells hyperglycaemic mice. We used streptozotocin model to achieve hyperglycaemia. Each sample contains cells from 4 different mice and hashing was done to allow disentangling which cell comes from which condition. Hashing was done with biolegend antibodies: Sample1: B0303: control 1, B0304 control 2, B0305 STZ 1, B0306 STZ 2 Sample2: B0303: control 3, B0304 control 4, B0305 STZ 3, B0306 STZ 4

Single cell transcriptomic analysis of bone marrow hematopoietic stem and progenitors cells isolated from 10-week-old wild-type control, Rps19R67∆/R67∆, Rps19R67∆/R67∆ Trp53−/− and Trp53−/− mutant mice.

Project description:This single cell transcriptome sequencing experiment is part of the study \\"Preclinical animal model of Diamond-Blackfan anemia with single amino acid mutation of ribosomal protein Rps19\\". A mouse model with this mutation develops features characteristic of human Diamond-Blackfan anemia, a rare bone marrow failure syndrome, including hematologic dysfunctions, early onset growth delay, intrinsic anemia, severe craniofacial, skeletal, urogenital, cardiovascular, and cerebral abnormalities leading to premature lethality during the adolescence of the mouse. This DBA mouse model exhibits cell intrinsic activation of the Trp53 signaling pathway in hematopoietic stem cells (HSCs) leading to reduced erythroid lineage development that may be rescued after inactivation of the tumor suppressor Trp53. The study uncovers that the development of the DBA phenotype significantly involves non-canonical components of the p53 signaling pathway in the etiopathogenesis of DBA with the Rps19R67∆ mutation leading to the disrupted hematopoietic hierarchy starting at the stage of short-term repopulating stem cells and the central role of induced Trp53 expression and upregulation of its non-canonical targets in the mediation of neural crest lineage deficiency-mediated development of craniofacial malformations in this model.

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 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.

Single-cell RNA-sequencing of cells from spinal cord central canal region of young adult and aged mice

Project description:The spinal cord neural stem cell potential is contained within the ependymal cells lining the central canal. This neural stem cell potential is known to decline with age in the mouse. Here, we microdissected and dissociated into single cells the central canal region from the spinal cord of 4 young adult (3-to-4-month old) and 4 aged (18-to-19-month old) C57BL/6J mice to profile the transcriptomes of cells in and around the central canal using 10x Genomics technology.

RNA-seq of hiPSCs-derived hepatocytes cultured in 3D and treated with oleic or palmitic acid

Project description:We aimed to develop an in vitro system that would recapitulate the key features of Non-Alcoholic Fatty Liver Disease (NAFLD). We took advantage of human pluripotent stem cells (hIPSCs) to establish 3D cultures of hIPSCs-derived hepatocytes to study NAFLD pathogenesis in vitro. Cultures were challenged with free fatty acid to mimic NAFLD, and transcriptomic analyses were used to confirm the presence of a NAFLD signature.

Single-nucleus RNA-seq of adult female and male mouse livers for sex-biased gene expression analyses

Project description:To obtain new insight into the sexual dimorphism of mammalian livers, single-nucleus RNA-seq was performed on the liver samples from two female and two male adult mice. The single-nucleus libraries were generated on the 10X Chromium Next GEM Single Cell 3ʹ platform and sequenced on Illumina NextSeq 550. We used the data to understand the heterogeneity and sex-biased gene expression of liver cell types. The data revealed significant sex differences primarily focused on hepatocytes. Specifically, from the sex-biased genes detected at the bulk tissue level, we observed that male-biased genes are more highly expressed in male hepatocytes, and female-biased genes are more highly expressed in female hepatocytes.

Single-cell sequencing of cerebral organoids with familial Alzheimer’s disease (AD) mutation in PSEN1 and non-demented control

Project description:We set up a 3D model based on iPSCs derived from patients with familial forms of Alzheimer’s disease (AD) and healthy non-demented control. We created cerebral organoids (COs), verified their ability to mimic AD in vitro, and used it to explore early events and the progression of AD pathogenesis. Our data reveal that despite similar expression of cell-type-specific genes during CO maturation in vitro, AD-iPSCs derived COs show limited tissue patterning and altered cellular development. These findings complement unique single-cell sequencing data of AD-iPSCs derived COs confirming this observation and uncovering that a sub-set of neurons in AD-iPSCs likely differentiates prematurely while at the same time retaining the expression of progenitor marker PAX6.
