Tumor growth inhibition of P@FPP NMs in vivo. A Schematic illustration of the treatment process in nude mice bearing tumor. B The changes of tumor volumes under different treatment process (n = 4). C The tumor weights under treatments of different formulations (n = 4). D The physical images of tumors treated with PBS, PRI, PTX, PRI + PTX, and P@FPP. E Representative images of H&E staining, IHC for Ki-67, and TUNEL (terminal deoxynucleotidyl transferase–mediated deoxyuridine triphosphate nick end labeling) staining of tumor tissues. scale bar of H&E staining: 200 μm. scale bar for IHC of Ki-67 and TUNEL staining: 100 μm. *: P < 0.05. ***: P < 0.001
