METTL3 knockdown enhances antitumor immunity and immune infiltration. a Bioluminescent images of intraperitoneal xenografted tumors from the indicated groups for Day 12 and Day 24. b The CD3⁺, CD4⁺ and CD8⁺ densities and PD-L1 expression were determined by Immunohistochemical analysis in the intraperitoneal xenografted tumors. Scale bar, 20 μm. c Images of subcutaneous tumors from the indicated groups (scale bar: 1 cm). d The CD3+, CD4+ and CD8+ densities and PD-L1 expression were determined by Immunohistochemical assay in the subcutaneous xenograft models. Scale bar, 20 μm
