Exosomes from PM -treated Human Bronchial Epithelial Cells Increase Lung Cancer Metastatic Potential.

Objective: Fine particulate matter (PM ) is an air pollutant that has become of great concern in recent years. Numerous studies have found that PM may contribute to lung cancer, but the pathogenesis has not yet been fully elucidated. In this study, we explored the roles of exosomes from bronchial epithelial cells in PM -promoted lung cancer metastasis.
