MiaPaCa-2 was purchased from ATCC. The murine cell line Panc02 was from Dr. Min Li (26 (link)). The murine cell line KPC was from Dr. Vonderheide (27 (link)). Cell line authentication was performed using short tandem repeat profiling. The cell lines tested negative for mycoplasma contamination. Cells were cultured in 5% CO2 at 37°C in Dulbecco’s modified Eagle’s medium (DMEM, Cellgro, Herndon, VA) containing 10% fetal bovine serum (Gemini, Woodland, CA) and 50 U/ml penicillin/streptomycin (Cellgro, Herndon, VA).
