The results similarly revealed significant positive correlations between the expression levels of EpCAM (r = 0.78, p = 0.022), CD51 (r = 0.82, p = 0.014), and CD49b (r = 0.85, p = 0.007) in tumor tissues and those observed in paired EVs isolated from plasma samples (Figure 1D). This evidence concerns the gene ITGA2 and neoplasm.
