Fisetin alleviated OVA-challenged airway remodeling. (A) Histopathological analysis was performed using H&E staining. (B) Quantification of WAm/Pbm (n = 5). (C) Collagen accumulation was detected through Masson staining. (D) Quantification of Masson stained area/Pbm (n = 5). (E) Goblet cell hyperplasia was detected using PAS staining. (F) Quantification of PAS stained area/Pbm (n = 5). Results are represented as the mean ± SEM. ^***P < 0.001 vs. control, ^#P < 0.05, and ^##P < 0.01 vs. OVA
