Figure 2From: FGF10 Signaling differences between type I pleuropulmonary blastoma and congenital cystic adenomatoid malformationImmunostaining with FGFR2b. From left to right, original magnification x 5 (A, C, E, G), x 40 (B, D, F, H). The x 40 magnified area is identified by a rectangle. Counterstain: hematoxilin. A-B: Control lung; strong FGFR2b expression in epithelial cells of normal bronchi. C-D: CCAM; strong and continuous FGFR2b expression in the epithelium lining the cysts. E-H: Multiloculated cysts in type I PPB: No staining (E-F) or focal staining (G-H) for FGFR2b.Back to article page
