In situ hybridization analysis of Fgf10 and its upstream transcriptional regulators in TβRIIΔ/Δ and control lungs. A, whole mount (panels a, b, e, and f) and section (panels c, d, g, and h) in situ hybridization. Note expansion and increased Fgf10 expression in TβRIIΔ/Δ (panels e–h) compared with TβRIIfl/fl (panels a–d) lungs. Scale bar, 2.2 mm (panels a and c); 1 mm (panels b and d); 100 μm (panels e–h). B, section in situ hybridization for Foxf1 (panels a and d), Tbx5 (panels b and e), and Tbx4 (panels c and f) in TβRIIΔ/Δ and TβRIIfl/fl (control) E15.5 lungs. Scale bar, 100 μm. C, quantification of Foxf1 and Tbx4 mRNA by real-time PCR. Values are fold induction or repression, compared with TβRIIfl/fl controls (arbitrarily adjusted to 1). p value, 0.004.
