MKI67 and non-small cell lung carcinoma: Ki‐67 staining was employed to detect cell proliferation, flow cytometry was performed to analyze cell apoptosis, RT‐qPCR and Western blot were used to measure mRNA and protein expression levels, and Transwell assays were conducted to assess cell migration and invasion capabilities to investigate the molecular mechanisms underlying the miRNA‐mediated regulation of TAM polarization by NSCLC‐derived EVs.
