Fig. 4From: Mesenchymal adenomatous polyposis coli plays critical and diverse roles in regulating lung developmentPhenotypic changes of E13.5 lungs with Apc and Ctnnb1 double conditional knockout in lung mesenchyme. Lung tissues with indicated Apc and Ctnnb1 genotypes were shown by gross view (a) and H&E-stained tissue sections (b). All fetal lungs shown here were positive for Tbx4-rtTA and TetO-Cre transgenes. Dox induction was started from E10.5Back to article page
