Fig. 6. PEDF inhibits the areas of α-smooth muscle actin (SMA) in a murine model of asthma. Peribronchial α-SMA immunostaining (immunohistochemistry, original magnification ×200) of lung tissue from (A) control group, (B) OVA group, (C) PEDF low group, and (D) PEDF high group. (E) Quantitative analyses of immunostaining area for peribronchial α-SMA. Data are presented as means±SEM (n=8 per group). ^*P<0.05 compared to the control group; ^**P<0.05 compared to the OVA group.
