Combined treatment with Pt@PCN-Cu and αPD-L1 enhances in vivo antitumor efficacy. (A) Schematic representation of the treatment schedule, with arrows indicating the time points of intravenous injections. (B) Representative photographs of tumors excised from different treatment groups. (C) Tumor growth curves of mice subjected to different treatments. (D) Ex vivo tumor weights measured at the end of the study. (E, F) Representative images of H&E staining (E) and Ki67 staining (F) of tumor tissues from mice treated with different regimens.
