As for anti‐tumor immunity evaluation, by flow cytometry, we observed an overall higher immune cell infiltration level in the Ctrl group in MC38 tumor models than that in 4T1 models (4T1: CD4+ T: 0.9450, CD8+ T: 1.695; MC38: CD4+ T: 15.88, CD8+ T: 24.33), indicating their activated immune status in the baseline (Figure 6i–p; Figures S26 and S27, Supporting Information). This evidence concerns the gene CD4 and neoplasm.
