Figure 2From: Remodeling of extra-bronchial lung vasculature following allergic airway inflammationSmooth muscle mass increase in both small and mid-sized blood vessels following allergen challenge. The area of vascular smooth muscle increased after allergen exposure, in small vessels approximately 5 times and in mid-sized approximately 3 times. Smooth muscle was detected by labelling with α-smooth muscle actin, and the positively stained area measured by digital image analysis and correlated to the length of the basement membrane (BM). The data are given as mean ± SEM and compared against control using the Wilcoxon Signed-ranks test, * indicates p < 0.05.Back to article page
