Single-Cell Transcriptomic Analysis of Human Lung Reveals Complex Multicellular Changes During Pulmonary Fibrosis

ABSTRACT: Pulmonary fibrosis is a heterogeneous syndrome in which fibrotic scar replaces normal lung tissue. We performed massively parallel single-cell RNA-Seq on lung tissue from eight lung transplant donors and eight patients with pulmonary fibrosis. Combined with in situ RNA hybridization, with amplification, these data provide a molecular atlas of disease pathobiology. We identified a distinct, novel population of profibrotic alveolar macrophages exclusively in patients with fibrosis. Within epithelial cells, the expression of genes involved in Wnt secretion and response was restricted to non-overlapping cells. We identified rare cell populations including airway stem cells and senescent cells emerging during pulmonary fibrosis. Analysis of a cryobiopsy specimen from a patient with early disease supports the clinical application of single-cell RNA-Seq to develop personalized approaches to therapy. This dataset contains single-cell RNA-seq data generated from the lungs of the two naive mice, human data for this study has been submitted to dbGap/SRA.

A spatially restricted fibrotic niche in pulmonary fibrosis is sustained by M-CSF/M-CSFR signaling in monocyte-derived alveolar macrophages

Project description:Pulmonary fibrosis is a heterogenous syndrome in which fibrotic scar replaces normal lung tissue. We performed single-cell RNA-seq on the lungs from mice exposed to fibrogenic particle (asbestos) and non-fibrogenic particle (TiO2) 14 days after the exposure to dissect cellular interactions unfolding during the early stages of the pulmonary fibrosis.

Translational co-culture model reveals epithelial-mesenchymal mechanisms of lung fibrosis and identifies NF-κB as potential therapeutic target

Project description:The interaction of lung epithelial and lung mesenchymal cells was investigated in a novel co-culture model of human pulmonary fibrosis. Remarkably, co-culturing both cell types induced cell-type-specific responses, including fibroblast-to-myofibroblast differentiation and epithelial-to-mesenchymal transition (EMT), which were fully dependent on direct epithelial / fibroblast contact. We used single-cell RNA sequencing (scRNA-seq) to evaluate the transcriptional fate of the normal human lung fibroblasts (NHLF) and normal human bronchiolar epithelial cells (NHBE) during the course of co-cultivation, and compare the single cell profiles with their counterpart isolated from patients with idiopathic pulmonary fibrosis (IPF). NHLF and normal NHBE cells were grown as co-cultures, cell suspensions were collected at the time points t = 0h, 3h and 18h and analyzed by single-cell RNA-seq on a Chromium Platform. Eight samples were sequenced, resulting in a total of xx single cell transcription profiles.

Single cell RNAseq reconstruct normal and IPF lung epithelium

Project description:Tissue fibrosis is a common pathological outcome of chronic disease that markedly impairs organ function leading to morbidity and mortality. In the lung, idiopathic pulmonary fibrosis (IPF) is an insidious and fatal interstitial lung disease associated with declining pulmonary function. Single cell RNA sequencing was used to map epithelial cell types of the normal human airway and alveolaor as well as IPF explant tissue.

Lung endothelial cells regulate pulmonary fibrosis through FOXF1/R-Ras signaling (Mouse I).

Project description:Pulmonary fibrosis results from dysregulated repair of damaged tissue caused by persistent injury of lung epithelium. Multiple cell types in the lung are involved in the process of repair. During lung fibrogenesis, normal endothelial cells (EC) are re-programmed into fibrosis-associated EC. Transcriptional factors that control re-programming are poorly understood. Using single cell RNA-sequencing of EC from donor and idiopathic pulmonary fibrosis (IPF) lungs, and lungs from bleomycin-treated mice, we identified endothelial transcription factors (TF) that were differentially expressed during fibrosis. Focusing on one of endothelial TF, FOXF1, we demonstrated that FOXF1 is decreased in EC within human IPF and mouse bleomycin-injured fibrotic lungs.
