Role of bone marrow mesenchymal stem cells in the development of PQ‑induced pulmonary fibrosis.

Abstract:

:Paraquat (PQ) poisoning‑induced pulmonary fibrosis is one of the primary causes of mortality in patients with PQ poisoning. The potential mechanism of PQ‑induced pulmonary fibrosis was thought to be mediated by inflammation. Recently, bone marrow‑derived mesenchymal stem cells (BMSCs) have been considered as a potential strategy for the treatment of fibrotic disease due to their anti‑inflammatory and immunosuppressive effects. In the present study, an increased accumulation of BMSCs in a mouse model of PQ‑induced pulmonary fibrosis following their transplantation, markedly improving the survival rate of mice with PQ poisoning. In addition, the results indicated that BMSC transplantation may inhibit the production of pro‑inflammatory cytokines, including tumor necrosis factor‑α interleukin (IL)‑1β, IL‑6 and IL‑10 in the lung tissues of PQ‑poisoned mice, and ultimately attenuate the pulmonary fibrosis. In vitro, BMSCs may suppress PQ‑induced epithelial‑to‑mesenchymal transition and protect pulmonary epithelial cells from PQ‑induced apoptosis. These findings suggest that BMSC transplantation may be a promising treatment for pulmonary fibrosis induced by PQ poisoning.
