Abstract
There is growing evidence suggesting that urban pollution has adverse effects on lung health. However, how urban pollution affects alveolar mesenchymal and epithelial stem cell niches remains unknown. This study aimed to determine how complex representative urban atmospheres alter alveolar stem cell niche properties. Mice were placed in an innovative chamber realistically simulating the atmosphere of a megalopolis, or "clean air," for 7 days. Lungs were collected, and fibroblasts and epithelial cells (EpCAM+) were isolated. Proliferative capacities of fibroblasts were tested by population doubling levels (PDL), and microarray analyses were performed. Fibroblasts and EpCAM+ cells from exposed, nonexposed, or naive mice were cocultured in organoid assays to assess the stem cell properties. Collagen deposition (Sirius red), lipofibroblasts (ADRP, COL1A1), myofibroblasts (αSMA), alveolar type 2 cells (AT2, SFTPC+), and alveolar differentiation intermediate cell [ADI, keratin-8-positive (KRT8+)/claudin-4-positive (CLDN4+)] markers were quantified in the lungs. Fibroblasts obtained from mice exposed to urban atmosphere had lower PDL and survival and produced fewer and smaller organoids. Microarray analysis showed a decrease of adipogenesis and an increase of genes associated with fibrosis, suggesting a lipofibroblast to myofibroblast transition. Collagen deposition and myofibroblast number increased in the lungs of urban atmosphere-exposed mice. AT2 number was reduced and associated with an increase in ADI cells KRT8+/CLDN4+. Furthermore, EpCAM+ cells from exposed mice also produced fewer and smaller organoids. In conclusion, urban atmosphere alters alveolar mesenchymal stem cell niche properties by inducing a lipofibroblast to myofibroblast shift. It also results in alveolar epithelial dysfunction and a fibrotic-like phenotype.NEW & NOTEWORTHY Urban pollution is known to have major adverse effects on lung health. To assess the effect of pollution on alveolar regeneration, we exposed adult mice to a simulated high-pollution urban atmosphere, using an innovative CESAM simulation chamber (Multiphase Atmospheric Experimental Simulation Chamber, https://cesam.cnrs.fr/). We demonstrated that urban atmosphere alters alveolar mesenchymal stem cell niche properties by inducing a lipofibroblast to myofibroblast shift and induces alveolar epithelial dysfunction.

Abstract
OBJECTIVE Researchers have investigated miR-130b-3p in lung disease pathology, such as lung fibrosis. The present study was performed to elucidate the miR-130b-3p-involved mechanism in acute lung injury (ALI) through delivery by mesenchymal stem cells-derived exosomes (MSCs-Exo). METHODS ALI mouse models were induced via intratracheal administration of lipopolysaccharide (LPS) and treated with MSCs-Exo. Lung dry-wet (W/D) ratio, inflammatory factors in the bronchoalveolar lavage fluid, pathological damage and apoptosis in the lung tissues were analyzed. Expression levels of miR-130b-3p and TGFBR1 were measured in the mouse lung tissues, and the interaction between miR-130b-3p and TGFBR1 was studied. RESULTS MSCs-Exo relieved LPS-induced ALI in mice by reducing lung W/D ratio and inflammatory response, and attenuating lung tissue pathological damage and reducing the alveolar cell apoptosis. miR-130b-3p delivery by MSCs-Exo reduced LPS-induced ALI in mice. TGFBR1 was determined to be a downstream target gene of miR-130b-3p. Inhibition of TGFBR1 could remit LPS-induced ALI in mice. The protection mediated by MSCs-Exo carrying miR-130b-3p could be rescued by elevating TGFBR1 expression. CONCLUSION miR-130b-3p delivery by MSCs-Exo confers protection on ALI in mice via the downregulation of TGFBR1.
