Cellular uptake and in vitro biological effects in different cells. (A) Time-dependent internalization of QD620/YC in RAW264.7 cells. (B) Cellular retention of QD620/YC in RAW264.7 cells. (C) Cell viability of RAW264.7 cells after incubation with various doses of PreCDDP/YC for 24 or 48 h. (D-H) Cytotoxicity of PreCDDP/YC in different tumor cells after incubation for 24 or 48 h, including HepG2 hepatocellular carcinoma cell (D), HeLa human cervical cancer cell (E), A549 human lung carcinoma cell (F), MCF-7 breast cancer cell (G), and multidrug resistant MCF-7 cell (MCF-7/ADR) (H). For all cell viability experiments, the indicated concentrations represent the doses of PreCDDP/YC. Scale bars in (A-B) represent 5 μm. Data are mean ± SD (n = 5).
