Effect of intraperitoneal treatment of MSC and EXO combination on mitochondrial, DAMPs and inflammation protein expression in acute CS exposed mouse lung. Whole lung homogenates were used for Western blot analysis against mitochondrial (anti-parkin, anti-Drp1, and anti-Opa1), DAMPs (anti-MMP9 and anti-HMGB1), and inflammation (anti-TSG6, anti-105, anti-p50 and anti-pP65) markers using antibodies. The protein abundance of mitochondrial, DAMPs and inflammation markers was measured following acute CS exposure in mouse lungs. The band intensity was measured by densitometry, and data are shown as relative intensity to β-actin as loading control. Data were shown as mean ± SEM (n=3/group). * P < 0.05.
