Comparison of cytotoxicity of chemotherapeutic agents against human BCa cell lines and normal urothelial cells in vitro. (A–D) Comparison of the killing rates of mitomycin at different concentration (0.5 and 1.0 mg/mL) against human BCa cell lines including BIU-87 (A), T24 (B), UMUC-3 (C), 5637 (D), and normal urothelial cell SV-HUC-1 measured using the CCK-8 assay at 0.5, 1, and 2 h (n = 3); E–H Comparison of killing rate of epirubicin at different concentration (0.5, 1.0 mg/mL) against human BCa cell lines including BIU-87 (E), T24 (F), UMUC-3 (G), 5637 (H), and normal urothelial cell SV-HUC-1 measured using the CCK-8 assay at 0.5, 1, and 2 h (n = 3). Data expressed as means ± SD were plotted, and Student’s t-test was used to compare two independent groups (A–H). *p < 0.05; ns, not significant
