Histological analysis of WT and ctnnb1Δex3 lungs at P28.

Abstract

<p>(A) WT ( = <i>Tyr::Cre</i>/°; +/+) and (B) ctnnb1Δex3 mice. Note the disorganized alveolae of the mutant lung. Nonetheless, the lung cells do not express the ctnnb1Δex3 transgene, suggesting that the effect is cell non-autonomous. Scale bars, (A, C, D)  = 50 µm, (B)  = 20 µm.</p
