Synergistic effects of interferon-alpha in combination with chemoradiation on human pancreatic adenocarcinoma

Figure 6 Expression of surface receptors Tumor cells were treated as described. Expressions of IFN and EGF receptors were analyzed after five-day treatment by flow cytometry. Data is shown as mean±SD error from eight cell lines each with at least four separate experiments. ^aP<0.05 was labeled with an asterisk; ^bP<0.01 with two asterisks and ^dP<0.001 with three asterisks.
