(Submitter supplied) We characterized senescent alveolar epithelial cells in an effort to better understand how these cells contribute to lung remodeling and fibrosis. The transcriptional profiles of several different types of senescent lung epithelial cells was evaluated using various induction methods in order to better understand core characteristics associated with the senescent program in epithelial cells of the lung.

(Submitter supplied) Recent publications have implicated senescent alveolar epithelial cells as the cause of lung remodeling and fibrosis. We sought to better understand the heterogeneity in the basal epithelial cell population, especially with regards to characterizing senescent alveolar epithelial cells. The basal cell cultures contain a portion of cells that display a senescent phenotype and stain for a marker of senescence. more...

(Submitter supplied) Epithelial senescence, specifically in the bronchiolized regions of the fibrotic lung, is apparent in IPF but not control tissue. In order to better understand the phenotype of these senescent cells we generated a in vitro culture model of senescence utillizing primary normal human bronchial epithelial cells. Cultures were treated with doxorubicin to induce senescence and the transcriptional phenotype of the senescent cultures was compared to DMSO-treated control cultures.

(Submitter supplied) To understand the cellular composition and transcriptional phenotype of fibrotic lung tissue we performed single-cell RNA-seq on stromal, immune, epithelial, and endothelial cell populations from human lung explants. Tissue was collected from normal control lungs, patients with idiopathic pulmonary fibrosis (IPF), and patients with systemic sclerosis associated interstitial lung disease (SSc-ILD). Using the 10X Genomics Chromium platform, we generated transcriptional profiles of approximately 200,500 cells across 4 IPF, 3 SSc-ILD and 3 normal control lungs.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) and systemic sclerosis-associated interstitial lung disease (SSc-ILD) differ in the predominant demographics and identified genetic risk alleles of affected patients, however both diseases frequently progress to respiratory failure and death. Contrasting advanced SSc-ILD to IPF provides insight to the role dysregulated immunity may play in pulmonary fibrosis. To analyze cell-type specific transcriptome commonalities and differences between IPF and SSc-ILD, we compared single-cell RNA-sequencing (scRNA-seq) of 21 explanted lung tissue specimens from patients with advanced IPF, SSc-ILD, and organ donor controls. more...

(Submitter supplied) Declining lung function in patients with interstitial lung disease is accompanied by epithelial remodeling and progressive scarring of the gas-exchange region. There is a need to better understand the contribution of basal cell hyperplasia and associated mucosecretory dysfunction to the development of idiopathic pulmonary fibrosis (IPF). Single cell RNA sequencing was used to map epithelial cell types of the normal and IPF human airway. more...

(Submitter supplied) Declining lung function in patients with interstitial lung disease is accompanied by epithelial remodeling and progressive scarring of the gas-exchange region. There is a need to better understand the contribution of basal cell hyperplasia and associated mucosecretory dysfunction to the development of idiopathic pulmonary fibrosis (IPF).We confirmed that Notch2 maintains undifferentiated basal cells and restrict basal-to-ciliated differentiation, and present evidence that Notch3 functions to restrain secretory differentiation. more...

(Submitter supplied) Myofibroblasts are key effector cells in the extracellular matrix remodeling of systemic sclerosis-associated interstitial lung disease (SSc-ILD), however the diversity of fibroblast populations present in the healthy and SSc-ILD lung is unknown, and has prevented the specific study of the myofibroblast transcriptome. We sought to identify and define the transcriptomes of myofibroblasts and other mesenchymal cell populations in human healthy and SSc-ILD lungs to understand how alterations in fibroblast phenotypes lead to SSc-ILD fibrosis.

(Submitter supplied) 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.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a fatal form of interstitial lung disease associated with progressive scarring of lung tissue and declining pulmonary function in aging individuals. Here we employ data mining and single cell RNA sequencing (scRNAseq) to define candidate drivers of AT2 senescence in IPF lung tissue. We show that AT2 cells isolated from IPF lung tissue exhibit characteristic features of cellular senescence and reduced abundance of Sin3a, critical determinant of endodermal progenitor cell maintenance in the developing lung. more...
