Fig. 4: Antitumor effect and tissue toxicity of Pt NCs against osteosarcoma in vivo.

A Macroscopic photos of nude mice and tumor bodies of xenograft tumor transplantation models of specific concentrations of PBS (blank control group), cisplatin (control group), and Pt NCs group (experimental group). B The macroscopic photographs and HE staining results of the heart, liver, spleen, lung, and kidney of the xenograft model represented the tissue toxicity of the drug. C Tumor body weight changes in xenograft model. D Body weight changes of nude mice in xenograft model.
