Decreased S100A9 Expression Promoted Rat Airway Smooth Muscle Cell Proliferation by Stimulating ROS Generation and Inhibiting p38 MAPK

Figure 2

Effect of stable knockdown of S100A9 expression on airway smooth muscle cellular proliferation. (a) PDGF-induced proliferation in ASMC-shRNA-S100A9 cells measured by the WST-1 assay at 24 h, 48 h, and 72 h. (b) PDGF-induced proliferation in ASMC-shRNA-S100A9 cells measured by the real-time cellular assay at 24 h, 48 h, and 72 h. indicates a significant difference as compared to control ASMCs (). All data are presented as the means ± SD, .
