CDH2 and hepatocellular carcinoma: Western blot analysis showed that BM‐EVs treatment increased the expression of mesenchymal markers, N‐cadherin, fibronectin 1 (FN1), and zinc finger E‐box binding homeobox 1 (ZEB1), and downregulated the epithelial marker E‐cadherin in HCC cells compared to their respective control cells (Figure 2H).
