Normalized MFI of surface E-cadherin in PDA cells treated with DMSO, 2.5μM Ionomycin (IONO), and 10ng/ml TGFβ for 7 days, followed by withdrawal of Ionomycin or TGFβ for 7 days as indicated on the x-axis. Treated cells were analyzed at day 2, 3, and 7. Withdrawn cells were analyzed on days 1, 2, and 7. Experiment was performed in duplicate in two different murine PDA cell lines. Error bars indicate SD.
