Optimizing Cultural Conditions for Duct Cells

  • Author / Creator

  • In-vitro expansion of the duct cells of the pancreas was associated with loss of the epithelial phenotype of these cells and acquisition of mesenchymal phenotype. These changes have been explained by epithelial mesenchymal transition. We have tested the effect of several growth factors that have been used in epithelial cell cultures with a number of different base media. We used geneticin that has been used to limit the growth of mesenchymal cells. Flow cytometry was employed to determine the percentages of EpCAM and Vimentin positive cells in the NEPT. The use of geneticin was helpful in preserving epithelial cells (~70% EpCAM positive cells) compared to the control (56% EpCAM positive cells) after a week in culture. Moreover we observed that a pancreatic media yielded the highest percentage of EpCAM positive cells (27%) and the lowest percentage of Vimentin positive cells (55%) compared to conventional media after 20 days in vitro.
