Characterization of murine non-hematopoietic bone marrow cells in non-fibrotic, pre-fibrotic and fibrotic conditions

ABSTRACT: We isolated non-hematopoietic cells from fibrotic and non-fibrotic mouse bone marrow and perfomed scRNAseq on them. We identified 8 different stromal populations. Our analysis revealed two distinct mesenchymal stromal cells (MSC) subsets as pro-fibrotic cells. MSCs were functionally reprogrammed in a stagedependent manner with loss of their progenitor status and initiation of differentiation in the prefibrotic stage and acquisition of a pro-fibrotic and inflammatory phenotype in the fibrotic stage. In parallel, IL-33-expressing myelinating Schwann cell progenitors expanded, likely as a repair mechanism for the previously described neuropathy in MPN.

Characterization of human non-hematopoietic bone marrow cells in non-fibrotic and fibrotic conditions

Project description:We isolated non-hematopoietic cells from fibrotic and non-fibrotic human bone marrow and perfomed scRNAseq on them. We identified 3 different stromal populations and 2 populations of hematopoietic progenitors. Our analysis revealed mesenchymal stromal cells (MSC) as pro-fibrotic cells. MSCs were functionally reprogrammed with loss of their progenitor status and acquisition of a pro-fibrotic phenotype in the fibrotic bone marrow. Additionally, stromal cells exhibited an upregulation of pro-inflammatory mediators like S100A8/A9.

Single Cell Analysis of Pulmonary Fibrotic Mesenchymal Cells Indicates a New Subtype

Project description:Stromal taxonomy consists of multiple cell subtypes that play a critical role in tissue repair or regeneration, fibrosis, inflammation, angiogenesis and tumor formation. However, their identities are not fully understood, as these conventional classified populations have historically been defined by restricted sets of markers. We performed single-cell RNA sequencing to investigate stromal mesenchymal cells (MCs) in normal and fibrotic mouse lung. Interrogated patterns of signature genes, lncRNAs, extracellular and plasma membrane genes, and top transcription factors expression were defined to characterize and classify 7 MC types in normal status. A specific new subset was discovered in fibrotic stage. Delineation of their differentiation trajectory was achieved by a machine learning method. This collection of transcriptional scRNA-seq data uncovered core information and provided a valuable resource for understanding the mesenchymal landscape in fibrotic diseases.

Macrophage epoxygenase determines a pro-fibrotic transcriptomesignature

Project description:Epoxygenases belong to the cytochrome P450 family and they generate epoxyeicosatrienoic acids (EETs) known to have anti-inflammatory effects but little is known about their role in macrophage function. By high-throughput sequencing of RNA (RNA-seq) in primary macrophages derived fromrodents and humans, we establish the relative expression of epoxygenases in these cells. Zinc-finger nuclease-mediated targeted gene deletion of the major rat macrophage epoxygenase Cyp2j4 (orthologue of human CYP2J2),resulted inreduced EET synthesis. Cyp2j4-/-macrophages have relatively increased PPARγ levels and show a pro-fibrotic transcriptome,displayingover-expression of a specific subset of genes (260 transcripts) primarily involved in extracellular matrix, with fibronectin being the most abundantly expressed transcript.Fibronectin expression is under the control of epoxygenase activity in human and rat primary macrophages. In keeping with the invitro findings, Cyp2j4-/- rats show up-regulation of type I collagen following unilateral ureter obstruction (UUO) of the kidney and quantitative proteomics analysis (LC-MS/MS) showed increased renal type I collagen and fibronectin protein abundance resulting from experimentally induced crescentic glomerulonephritis in these rats. Taken together, these results identify the rat epoxygenase Cyp2j4 as a determinant of a pro-fibrotic macrophage transcriptome that could have implications in various inflammatory conditions depending on macrophage function.

Transcription profiling of human GFAP-negative lamina cribrosa cells TGF-beta regulated gene transcription and protein expression

Project description:Primary open angle glaucoma (POAG) is a progressive optic neuropathy, which is a major cause of worldwide visual impairment and blindness. Pathological hallmarks of the glaucomatous optic nerve head include retinal ganglion cell axon loss and extracellular matrix (ECM) remodeling of the lamina cribrosa layer. TGF-beta is an important pro-fibrotic modulator of ECM metabolism, whose levels are elevated in human POAG lamina cribrosa tissue compared with non-glaucomatous controls. We treated human lamina cribrosa (LC) cells with TGF-beta1 (10ng/ml) for 24 hours in order to examine differential gene expression patterns in repsonse to this cytokine. In particular we focused on ECM and fibrotic genes. We found that TGF-beta1 induces expression and release of ECM components in LC cells, which may be important in regulating matrix remodeling in the lamina cribrosa. In disease states such as POAG, the LC cell may represent an important pro-fibrotic cell type and an attractive target for novel therapeutic strategies.

Systemic pro-fibrotic and pro-inflammatory response in patients with advanced cirrhosis

Project description:Objective: To evaluate gene expression profiles in patients with advanced cirrhosis compared with healthy controls (HC). Results: Patients with advanced cirrhosis exhibit an unbalanced systemic response involving pro-fibrotic / protective signatures that could be contributing to the pathogenesis of cirrhosis and also to that of the extra-hepatic complications of this disease.

Myeloid cell analysis during a pro-fibrotic ischemia-reperfusion and cardiotoxin muscle injury.

Project description:Myeloid cells are critical to the development of fibrosis following muscle injury, however, the mechanism of their role in fibrosis formation remains unclear. Here we demonstrate that myeloid cell-derived TGF-β1 signaling is increased in a pro-fibrotic ischemia-reperfusion and cardiotoxin (IR/CTX) muscle injury model. This study analyzes scRNAsequencing from the fibrotic region after a pro-fibrotic ischemia-reperfusion and cardiotoxin muscle injury.

CXCL8/CXCR2 signaling is Enriched in Fibrotic Myeloproliferative Neoplasms and is Vulnerable to Therapeutic Inhibition [RNA-Seq]

Project description:Pro-inflammatory signaling is a hallmark feature of human cancer, including in myeloproliferative neoplasms (MPNs), most notably myelofibrosis (MF). Dysregulated inflammatory signaling contributes to fibrotic progression in MF; however, the individual cytokine mediators elicited by malignant MPN cells to promote collagen-producing fibrosis and disease evolution remain yet to be fully elucidated. Previously we identified a critical role for combined constitutive JAK/STAT and aberrant NF-kB pro-inflammatory signaling in myelofibrosis development. Using single-cell transcriptional and cytokine-secretion studies of primary MF patient cells and two separate murine models of myelofibrosis, we extend this previous work and delineate the role of CXCL8/CXCR2 signaling in MF pathogenesis and bone marrow fibrosis progression. MF patient hematopoietic stem/progenitor cells are enriched in a CXCL8/CXCR2 gene signature and display dose-dependent proliferation and fitness in response to exogenous CXCL8 ligand in vitro. Genetic deletion of Cxcr2 in the hMPLW515L adoptive transfer model abrogates fibrosis and extends overall survival, and pharmacologic inhibition of the CXCR1/2 pathway improves hematologic parameters, attenuates bone marrow fibrosis, and synergizes with JAK inhibitor therapy. Our mechanistic insights provide a rationale for therapeutic targeting of the CXCL8/CXCR2 pathway in MF patients at risk for continued fibrotic progression.
