Figure 3From: Effects of exercise training on pulmonary vessel muscularization and right ventricular function in an animal model of COPDMuscularization of pulmonary vessels in mice exposed to cigarette smoke (CS) or fresh air (FA) and put through 4 weeks of interval training (IT) or kept sedentary for 4 weeks (Se). Staining of smooth muscle actin was evaluated on a scale of 1-5 (1 = non-muscularized to 5 = fully muscularized). Bars indicate mean ± SD. *p = 0.040 (main effect of IT vs Se, 2-way ANOVA without interaction-term).Back to article page
