Dedifferentiation of pancreatic exocrine fractions is accompanied by EMT. Immunocytochemistry of plated pancreatic exocrine
fractions was performed from day 2 to day 18 in culture. The pancreatic exocrine markers amylase (AML) and CK19, the epithelial
marker E-cadherin (ECAD), and the mesenchymal marker vimentin (VIM) expressions were analyzed on days 2, 4, 10, and 18 of
culture. Nuclei were counterstained with DAPI. Scale bar = 20 μm.
