The hematoxylin‐eosin (HE), Ki67, and terminal deoxynucleotidyl transferase‐mediated dutp nick‐end labeling (TUNEL) staining results demonstrated significant differences among the treatment groups, revealing fewer tumor cells (Figure S13, Supporting Information), decreased cell proliferation, and enhanced apoptosis in the 125I group. Here, MKI67 is linked to neoplasm.
