MKI67 and neoplasm: Additionally, compared with the subcutaneous allografts derived from ITM2BWT‐expressing Renca cells, ITM2BI115A‐expressing Renca cell‐derived allografts presented delayed tumor growth and reduced Ki67 expression; however, the injection of migrasomes derived from ITM2BWT‐expressing Renca cells effectively rescued tumor growth and tumor cell proliferation to the levels of ITM2BWT‐expressing allografts (Figure 2I,J).
