Figure 3. Evaluation of apoptosis of gefitinib alone or combined with metformin on 3 bladder cancer cell lines MB49, UMUC3 and T24.
(A) Representative flow cytometry scatter plots of propidium iodide (PI) (Y axis) vs Annexin-fluorescein isothiocyanate (FITC) (X axis). (B) Bar charts show quantitative data of average of 3 independent flow cytometry experiments in MB49 cells (*P < 0.05, #P < 0.01 compared with control). (C) Bar charts show quantitative data of average of 3 independent flow cytometry experiments in T24 and UMUC3 cells (*P < 0.05, #P < 0.01 compared with control).
