H&E staining of lung specimens in WT and TRPV2KO mice. a H&E staining of the lung from TRPV2KO mice of 2, 4, and 8-month-old (magnification, × 100; scale bar, 100 μm). b H&E staining of the lung from WT and TRPV2KO mice that were exposed to cigarette smoke for 2 months (magnification, × 100; scale bar, 100 μm). c The change of mean linear intercept in TRPV2KO mice. *p < 0.01. d The change of mean linear intercept by 2 months cigarette smoke exposure in WT and TRPV2KO mice. *p < 0.05. **p < 0.01. Mean linear intercept (Lm; average distance between alveolar walls) was measured by light microscopy
