Inhalation of Lung Spheroid Cell-Secreted Factors and Exosomes Promotes Therapeutic Lung Repair in Rodent Models of Pulmonary Fibrosis

ABSTRACT: Idiopathic pulmonary fibrosis (IPF) is a fatal form of interstitial lung disease in which persistent injury results in scar tissue formation. As fibrosis thickens, the lung tissue becomes stiff and losses the ability to facilitate gas exchange and provide cells with needed oxygen. Currently, IPF has few treatment options and no effective therapies, aside from lung transplant. Here we present a series of studies utilizing lung spheroid cell-derived conditioned media (LSC-CM) and exosomes (LSC-EXO) to treat different rodent models of lung injury and fibrosis. Inhalation treatment was given for seven consecutive days via a nebulizer for clinical relevance. Results revealed that LSC-CM and LSC-EXO treatments could attenuate and resolve bleomycin- and silica-induced fibrosis by reestablishing normal alveolar structure, decreasing collagen accumulation, and myofibroblast proliferation. In addition, LSC-CM and LSC-EXOs exhibited superior therapeutic benefits than their counterparts derived from bone marrow mesenchymal stem cells. LSC-CM and LSC-EXOs provide promising therapeutic options for pulmonary fibrosis.

Mapping spatially resolved transcriptomes in human and mouse pulmonary fibrosis

Project description:Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with poor prognosis and limited treatment options. Efforts to identify effective treatments are thwarted by limited understanding of IPF pathogenesis and poor translatability of available preclinical models. To address these limitations, we generated spatially resolved transcriptome maps of human IPF and bleomycin-induced mouse lung fibrosis.

Mouse Nedd4-2 and control with Pirfenidone

Project description:Idiopathic pulmonary fibrosis (IPF) is a chronic progressive interstitial lung disease characterized by patchy scarring of the distal lung with limited therapeutic options and poor prognosis. Here, we show that conditional deletion of the ubiquitin ligase Nedd4-2 in lung epithelial cells in adult mice produces chronic lung disease that shares key features with IPF including progressive fibrosis and bronchiolization with increased expression of Muc5b in peripheral airways, honeycombing and characteristic alterations in the lung proteome.

MicroRNA expression data from lung tissue of Idiopathic Pulmonary Fibrosis

Project description:Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and usually lethal lung disease characterized by unknown causes and few treatment options We used microarray to determine the expression of miRNA and 17 miRNAs were differentially expressed in IPF lungs, including 10 upregulated and 7 downregulated miRNAs. Lung tissue was obtained from 4 IPF patients with histological evidence of usual interstitial pneumonia at the time of surgical lung biopsy or lung transplantation. The diagnosis of IPF was derived according to the standards accepted by the American Thoracic Society/European Respiratory Society. Histological normal lung tissues used as controls was obtained from 3 patients with primary spontaneous pneumothorax at the time of thoracoscopy with stapling of any air leak.The miRNA expression profile was determined by Affymetrix microarray, and transcriptome with Affymetrix array

MicroRNA and protein cargos of human limbal epithelial cell-derived exosomes and their regulatory roles in limbal stromal cells of diabetic and non-diabetic cornea

Project description:Epithelial and stromal/mesenchymal limbal stem cells contribute to corneal homeostasis and cell renewal. Extracellular vesicles (EVs), including exosomes (Exos), can be paracrine mediators of intercellular communication. Previously, we described cargos and regulatory roles of limbal stromal cell (LSC)-derived Exos in non-diabetic (N) and diabetic (DM) limbal epithelial cells (LEC). Presently, we quantify the miRNA and proteome profiles of human LEC-derived Exos and their regulatory roles in N- and DM-LSC. We revealed some miRNA and protein differences in DM vs. N-LEC-derived Exos' cargos including proteins involved in Exo biogenesis and packaging that may affect Exo production and ultimately cellular crosstalk and corneal function. Treatment by N-Exos, but not by DM-Exos enhanced wound healing in cultured N-LSC and increased proliferation rate in N and DM LSCs vs. corresponding untreated (control) cells. N-Exos treated LSC reduced keratocyte markers ALDH3A1 and lumican, and increased MSC markers CD73, CD90 and CD105 vs. control LSC. These being opposite to the changes quantified in wounded LSCs. Overall, N-LEC Exos have a more pronounced effect on LSC wound healing, proliferation, and stem cell marker expression than DM-LEC Exos. This suggests that regulatory miRNA and protein cargo differences in DM- vs. N-LEC-derived Exos could contribute to the disease state.

Gene network analysis of interstitial macrophages after treatment with induced pluripotent stem cells secretome (iPSC-cm) in the bleomycin injured rat lung

Project description:Idiopathic pulmonary fibrosis (IPF) is a complex disease involving various cell types. Macrophages are essential in maintenance of physiological homeostasis, wound repair and fibrosis in the lung. Macrophages play a crucial role in repair and remodeling by altering their phenotype and secretory pattern in response to injury. The secretome of induced pluripotent stem cells (iPSC-cm) attenuates injury and fibrosis in bleomycin injured rat lungs. In the current study, we evaluate the effect of iPSC-cm on interstitial macrophage gene expression and phenotype in bleomycin injured rat lungs in vivo. Â iPSC-cm was intratracheally instilled 7 days after bleomycin induced lung injury and assessed 7 days later and single cell isolation was performed. Macrophages were FACS sorted and microarray analysis was performed. We characterized changes in the rat lung interstitial macrophages using transcriptional profiling.

Transcription profiling of human myofibroblasts isolated from patients with idiopathic pulmonary fibrosis

Project description:Idiopathic pulmonary fibrosis (IPF), a chronic progressive lung disease of unknown etiology, is characterized by the expansion of myofibroblasts and abnormal deposition of extracellular matrix in the lung parenchyma. To elucidate the molecular mechanisms that lead to IPF, we analyzed myofibroblasts established from patients with IPF by oligonucleotide microarrays. Gene expression profiles revealed a novel pathophysiologic function of myofibroblasts as a generator of reactive oxygen species, and a self-defense mechanism against oxidative stress of their own generating. Experiment Overall Design: We isolated two myofibroblast cell culture from patients with idiopathic pulmonary fibrosis. Embryonic pulmonary fibroblast was used for the reference.
