Immunohistochemistry results showed that, compared with the control group, the intratumor‐injected MLTCs group had higher Ki67, Vimentin, Twist1, and VEGFR1 scores and lower E‐cadherin scores, indicating that MLTCs promoted the proliferation of tumor cells and induced epithelial‐mesenchymal transformation (EMT) of tumor cells (Figure S6, Supporting Information). This evidence concerns the gene TWIST1 and neoplasm.
