KIC mice (6-8 weeks) and PDA primary cells in culture co-expressed Rgs16::GFP with markers of pancreatic progenitor cells and epithelial-mesenchymal transition (EMT), such as Sox9, Muc1 and Ecad (Fig. 4, Fig. 5C; β-catenin and TGF-β supplementary material Fig. S8). This evidence concerns the gene MUC1 and Patent ductus arteriosus.
