| Research Abstract |
Current evidence suggests that the pathogenesis of pulmonary fibrosis might be due to the heterogeneity of fibroblast origins. In this study, persistent tissue hypoxia might be involved in active fibrosis in an in vivo model of BLM-induced lung injury/fibrosis, likely due to endothelial-mesenchymal transition. These findings indicate that persistent tissue hypoxia as tissue microenvironment may promote secondary EMT and lung fibrosis. These also indicate the clue to understand the underlying mechanism of lung fibrosis, leading the new therapeutic strategy.
