Figure 2 Cell differentiation program in the pancreas. PDX1 and Ptf1a genes are expressed on E8.5-9.5 d, which determines the cell fate in the pancreas epithelium. By using the PDX1 or Ptf1a gene promoter-induced Cre-loxP system, all three lineages (islet, acini and duct) have the designed genetic alterations. The cell of origin of pancreatic ductal adenocarcinoma (PDAC) is still under discussion. Experimentally, PDAC can be derived from all three lineages.
