Fig. 4From: The epithelial-to-mesenchymal transition induced by tumor-associated macrophages confers chemoresistance in peritoneally disseminated pancreatic cancerCancer cells show chemoresistance after co-culture with macrophages. Panc1 and BxPC-3 cells cultured with macrophages were exposed to gemcitabine for 48 h at different concentrations. Cell viability was measured in triplicate by XTT assay, and representative results are shown as means ± S.D. The calculated IC50 is shown in the lower tablesBack to article page
