The expressions of CEP55 and Ki67 were detected by immunohistochemistry (Figure 8B) and Western blot analysis (Figure 8C), the results of which revealed down‐regulated expressions of CEP55 and Ki67 in tumour tissues of nude mice bearing SiHa cells co‐cultured with miR‐144‐3p‐treated EVs. Here, MKI67 is linked to neoplasm.
