Fig. 6. FOXA1, FOXJ1, PECAM and elastin staining. Lung sections were prepared on PN16. Triple transgenic mice, SP-C-rtTA^-/tg, (tetO)₇CMV-Cre^-/tg, Foxa2^loxP/loxP and littermate controls were maintained on doxycycline from E0. (A-H) Lung sections were stained for FOXA1 (A,B), FOXJ1 (C,D), PECAM (E,F), and elastin (G,H). Inserts are higher magnifications (x40). Figures are representative of at least four individual mice of each genotype. Scale bar: 100 µm.
