Panc-1 and BxPC-3 were pretreated with resveratrol at different concentrations (50 and 100 μM) for 24 h and then inoculated in serum-free DMEM/F12 medium (containing 20 ng/ml EGF, 20 ng/ml FGF, and 1% B27) for 1 week to determine the ability of the cancer cells to form pellets. The gene discussed is EGF; the disease is cancer.
