Antitumor activities of DOX‐loaded PTAO‐PCL micelles against orthotopic MCF‐7/ADR tumors. a) Tumor growth curves of the mice. b) Photographs of the tumors resected at the end of the experiment. c) Averaged tumor weight of each group at the experimental endpoint and tumor inhibition rates (TIR). d) Body weight variation of the mice during the experiment. e) Representative histological features of the tumors and hearts. The 10‐µm‐thick tissue sections were stained with hematoxylin‐eosin and observed using light microscopy. Scale bar: 50 µm. ^* p < 0.05, ^** p < 0.01, ^*** P < 0.001.
