However, the difficulty in engraftment and easy clearance of BMSCs in vivo has hindered their clinical application. Hence, exploring effective methods to improve the engraftment and differentiation rates of BMSCs in vivo is urgent.Methods: We constructed BMSCs overexpressing Wnt3a by lentivirus infection and transplanted them into a COPD rat model. The damage level of COPD rat lung tissue was assessed by pathology analysis and inflammatory cytokines analysis. The engraftment of BMSC was detected by immunofluorescence staining. Statistical analysis was performed using GraphPad Prism 7.Results: We found that Wnt3a significantly enhanced the engraftment rate of BMSCs in the lungs of rats and further increased their differentiation rate into type II alveolar epithelial cells. We also assessed the expression of inflammatory factors in the lung tissues of COPD rats and discovered that Wnt3a reduced the levels of the inflammatory factors IL-6 and IL-1β while increasing the level of the anti-inflammatory factor IL-10. Our study demonstrates that Wnt3a can improve the engraftment and differentiation rates of BMSCs in the host and further alleviate COPD symptoms by regulating the secretion of inflammatory factors.Conclusion: Constructing BMSCs overexpressing Wnt3a could serve as a new strategy for stem cell therapy in COPD.Keywords: Wnt3a, BMSCs, COPD, inflammatory cytokines |
