• tamoxifen-treated mice exhibit a rapid transformation of YFP+ centroacinar cells into acinar cells compared with control mice
• however, tamoxifen-treated mice exhibit normal centroacinar and acinar cells proliferation and apoptosis

N normal phenotype
endocrine/exocrine glands
• pancreatic progenitor cells (GFP +ve) form cystic structures, not narrow, branched structures, that lack endocrine or acinar marker expression with tamoxifen treatment (2 mg) at E9.5 or 11.5
• treatment at E13.5 or 15.5 blocks islet differentiation, but some exocrine differentiation occurs, with labeled cells integrating into normal acini and ducts
• treatment with 0.5 mg tamoxifen at E9.5 still results in formation of abnormal cystic tubules as seen with the higher dose
• Notch 1 activation at E13.5 results in most GFP +ve cells adopting a ductal, rather than acinar, fate; activation at E15.5 reverses the proportions with most cells taking an acinar fate
