FABP4 deficiency attenuates VEGF-induced angiogenesis in mouse airways. A: Mice were given dox-water for 3 days. Tracheas were harvested, fixed in 10% formalin, and embedded in paraffin. Immunofluorescence analysis was performed for CD31. Representative images are shown. Scale bar = 25 μm. B: CD31⁺ endothelial cells localized between the airway lumen and posterior border of the cartilage plates were counted and normalized to the area described. Bar graph represents means ± SEM values from 5 to 7 mice per group. ^∗P < 0.05, ^∗∗P < 0.01.
