Single cell RNA-seq to delineate the gene expression of bone marrow cells

ABSTRACT: Purpose: The goal of this study is to investigate the role of integrin beta3 (Itgb3) deficiency on the gene expression of bone marrow cells. Methods: Bone marrow was harvested by flushing the femurs and tibias of Apoe(-/-), Itgb3(+/+) and Apoe(-/-), Itgb3(-/-) mice in PBS with 2% fetal bovine serum on ice. Cells were isolated from bone marrow by density gradient centrifugation using Lympholyte (Cedarlane, CL0531). After centrifugation at 1300 g for 20 min, bone marrow cells were collected from the interface and washed in Ca2+/Mg2+ - free HBSS and dissociated to a single-cell suspension by filtering through a 70-µm nylon mesh. The cells were then subjected to 10X Genomics single cell 3’ RNA-seq libraries construction and sequencing. scRNA-seq data was processed with Cell Ranger v 3.1.0. Reads were aligned to a modified version of the mouse transcriptome mm10. The top cell barcodes selected by Cell Ranger were utilized for downstream analysis. Results: Expression profiles of the transcriptome are compared between cell types isolated from the bone marrow of Apoe(-/-), Itgb3(+/+) and Apoe(-/-), Itgb3(-/-) mice. Conclusions: Significant differences in the expression profile of genes are present in bone marrow cells of Apoe(-/-), Itgb3(+/+) and Apoe(-/-), Itgb3(-/-) genotypes.

The effects of beta-3 adrenergic innervation on bone marrow cells

Project description:The activity of bone marrow hematopoeitic cells is tightly controlled by neurogenic innervations. As bone marrow cells mainly receive innervation from beta-3 adrenergic receptor, here we investigated the impact of beta3-adrenergic innervation on bone marrow cell transcriptome alterations. We sorted hematopoetic stem cells (HSCs) from wild type mice (control group) or Adrb3-/- mice (devoid of beta3-adrenergic receptor). Thereafter, Nanostring assessment was performed to compare the transcriptome alterations.

Age of the bone marrow dictates clonality of smooth muscle-derived cells in the atherosclerotic plaque [bulk RNA-seq]

Project description:Purpose: The goal of this study is to investigate the gene expression in aged (18 month old) and young (3 month old) bone marrow-derived monocytes. Methods: Bone marrow was harvested by flushing the femurs and tibias of young (3 month old) and aged (18 month old) mice in PBS with 2% fetal bovine serum (FBS) on ice. Cells were isolated from bone marrow by density gradient centrifugation using Lympholyte (Cedarlane, CL0531). After centrifugation at 1300 g for 20 min, bone marrow cells were collected from the interface and washed in Ca2+/Mg2+ - free HBSS. The cells were dissociated to a single-cell suspension by filtering through a 70-µm nylon mesh. For monocyte isolation, a suspension of bone marrow cells was stained with Alexa 700 anti-CD3 (1:100, BioLegend, 100215), PE-Cy7 anti-CD19 (1:100, BioLegend, 115520), FITC anti-CD11b (1:100, BD Pharmingen, 553310) and APC anti-Ly6c antibodies (1:100, BioLegend, 128015) in PBS with 0.5% FBS for 30 min. CD11b+Ly6c+CD3-CD19- monocytes were isolated with a BD FACSAria cell sorter. Total RNA was extracted and subjected to bulk RNA-seq using Illumina HiSeq 2000. Results: Expression profiles of the transcriptome are compared between bone marrow-derived monocytes isolated from aged (18 month old) and young (3 month old) mice. Conclusions: Significant differences in the expression levels of genes are noted between the two age groups.

Effect of macrophage SNO-Septin2 in aortic aneurysm development

Project description:We analyzed differentially expressed genes in aortas from Apoe-/- mice that received Apoe-/- bone marrow or Apoe-/-Sept2C111A bone marrow and were infused with Ang II for 28 days to explore the mechanisms of macrophage SNO-Septin2 in aortic aneurysm development.

Quantitative analysis of miRNA changes in bone marrow stem cells under neural differentiation

Project description:Normal SJL mice, 6 to 8 weeks old, were used for the isolation of bone marrow stem cells (BMSC). Bone marrow cells were obtained from the femurs and tibias of euthanized mice by flushing with PBS. Cells were subjected to negative magnetic sorting using the Lineage Cell Depletion Kit. Isolation of murine bone marrow Lin-Sca-1+ cells was performed using MACS Sca-1 MultiSort Kit (fBMSC). The differentiation of neural stem cells was induced by removing the bFGF-containing medium and resuspending cells in fresh bFGF-free medium. Microarray analysis of miRNA expression profiles was performed comparing non differentiated bone marrow stem cells (fBMSC) to bone marrow stem cells differentiated for 4 or 7 days.

Single cell RNA sequencing to identify the PDGFR-β expressing lung cells

Project description:Purpose:Single cell RNA sequencing to identify PDGFR-beta expressing cells in the normal adult lung Methods: Adult Pdgfrb-CreERT2, ROSA26R(Zs/+) mice were induced with tamoxifen (1mg/day for 5 days) and rested for 5 days. Lungs were then harvested and prepared to obtain single cell suspension. Live Zs+ and Zs- cells were isolated by FACS and hash-tagged. Cells were then pooled together in PBS with 0.04% bovine serum albumin and subjected to library preparation and DropSeq. scRNA-seq data was processed with Cell Ranger v 3.1.0. Reads were aligned to a modified version of the mouse transcriptome mm10, including the sequence for the gene ZsGreen1. The top cell barcodes selected by Cell Ranger were utilized for downstream analysis. Results: In lung mesenchymal cells, populations of fibroblasts and pericytes express Pdgfr-beta.

Transcriptional program of terminal granulocytic differentation

Project description:To characterize the transcriptional program that governs terminal granulocytic differentation in vivo, we performed comprehensive microarray analysis of human bone marrow population highly enriched for promyelocytes, myelocytes / metamyelocytes and neotrophils. Bone marrow and peripheral blood samples were collected from healthy individuals in parallel. Cell populations representing successive stages of terminal granulocytic differentation were isolated from human bone marrow samples by 2-layer density gradient centrifugation, neutrophils were collected from peripheral blood using 1-layer density gradient centrifugation. All populations were depleted of nongranulocytic cells by immunomagnetic sorting.

scRNA-seq of sheep abomasal epithelial tissue post-nematode infection

Project description:Tuft cells are required for an effective immune response to gastrointestinal parasitic nematodes in mice, but little is known about tuft cells in other animals. Using scRNA-seq, we profiled the transcriptome of tuft cells and other mucosal cell types from the sheep abomasal epithelium following nematode infection. Cells were isolated from abomasum mucosal tissue of two sheep and processed using 10x Genomics Chromium Single Cell 3’ Reagent kit (v.3) using a total of 20,000 input cells. cDNA libraries were sequenced on an Illumina NextSeq 500 system to a depth of 50,000 read pairs per cell. Sequences were mapped to the genomes for ovine (Ovis aries Oar_v3.1; https://www.ensembl.org/Ovis_aries/Info/Index) and bovine (Bos taurus ARS-UCD1.2; https://www.ensembl.org/Bos_taurus/Info/Index) and gene count matrices generated using the Cell Ranger software (v.3.1.0) and analysed using Seurat package (v.3.1) with R version 3.6.0. The “Find Markers” function identified a tuft cell cluster and other distinct epithelial (Epcam+) and immune (Ptprc+) cell clusters.

Gene expression profiling of mouse bone marrow-derived macrophages (RNA-Seq)

Project description:Bone marrow (BM) cells were obtained by flushing the long bones of 8-week old C57BL/6 mice. BM cells were then were plated in macrophage SFM medium (Life Technologies) supplemented with penicillin-streptomycin and CSF-1 (Peprotech, 100 ng/ml) and cultured for one week to allow macrophage differentiation. BMDMs were polarized by adding IL-4 to the medium (40 ng/ml, Peprotech) for 72h or left untreated.
