Gemcitabine effect on cell viability after 72 h treatment on Capan-2 cells cultured as monolayer (open circle), spheroid in defined medium supplemented with EGF and B27 (black triangles), or as quiescent Capan-2 spheroid (gray squares). Each point is the mean ± SD of 3 replicates. Dose-response experiments were fitted with GraphPad Prism software.
