Retracted: M2 Macrophage–Derived Exosomes Facilitate HCC Metastasis by Transferring αMβ2 Integrin to Tumor Cells

Background and Aims The development and progression of hepatocellular carcinoma (HCC) is dependent on its local microenvironment. Tumor‐associated macrophages (TAMs) are deemed a key factor for the tumor microenvironment and attribute to contribute to tumor aggressiveness. However, the detailed mechanism underlying the pro‐metastatic effect of TAMs on HCC remains undefined. Approach and Results The present study proved that TAMs were enriched in...
