Figure 4. Airway narrowing heterogeneity at 3 min and 20 min after aerosol challenge with PBS or Ova.

(A) Illustration of bronchoconstriction in PBS and Ova-challenged animals (Scaling bar = 100 µm). (B) While there were no differences to report at 3 minutes (n = 5−6), (C) airway narrowing heterogeneity was greater in the Ova-challenged animals compared to controls at 20 minutes (n = 4−6, *p<0.05).
