Fig. 7. The apoptosis of MCF-7 and SMMC-7721 cells was evaluated by TUNEL assay. MCF-7 cells were incubated with DOX-loaded micelles for 24 h, 48 h, 72 h, SMMC-7721 cells were incubated with DOX-loaded micelles for 24 h, 48 h, 72 h (A). The nuclei of apoptotic cells were stained brown. The statistical apoptosis rate was shown in (B).
