Fig. 3From: Exosomal AP000439.2 from clear cell renal cell carcinoma induces M2 macrophage polarization to promote tumor progression through activation of STAT3M2 polarized macrophage induced by exosomes from ccRCC promoted the migration of ccRCC. The migration abilities of ccRCC treated with cell culture of macrophage were assessed by transwell experiment. The migrated cells were stained with crystal violet and observed by light microscopy (magnification, × 200). Data represents at least three experiments performed in triplicate. **p < 0.01, ***p < 0.001. Two-tailed Student’s t-testBack to article page
