Abstract Background Hepatocellular carcinoma (HCC) remains a global challenge due to its high morbidity and mortality rates as well as poor response to treatment. The communication between tumor-derived elements and stroma takes on a critical part in facilitating malignancy progression of HCC. Exosomes are small extracellular vesicles (EVs) that are released from your cells upon fusion of multivesicular body with the plasma membrane. There is emerging evidence indicating that exosomes play a central part in cell-to-cell communication. Much attention Clopidogrel thiolactone has been paid to exosomes since they are found to transport bioactive proteins, messenger RNA (mRNAs) and microRNA (miRNAs) that can be transferred in active form to adjacent cells or to distant organs. However, the mechanisms underlying such malignancy progression remain mainly unexplored. Methods Exosomes were isolated by differential ultracentrifugation from conditioned medium of HCC cells and recognized by electron microscopy and Western blotting analysis. Hepatic stellate cells (HSCs) were treated with different concentrations of exosomes, and the activation of HSCs was analyzed by Western blotting analysis, wound healing, migration assay, Edu assay, CCK-8 assay and circulation cytometry. Moreover, the different miRNA levels of exosomes were Clopidogrel thiolactone tested by real-time quantitative PCR (RT-PCR). The angiogenic ability of triggered HSCs was analyzed by qRT-PCR, CCK-8 assay and tube formation assay. In addition, the irregular lipid rate of metabolism of triggered HSCs was analyzed by Western blotting analysis and Oil Red staining. Finally, the relationship between serum exosomal miRNA-21 and prognosis of HCC individuals was evaluated. Results We showed that HCC cells exhibited a great capacity to convert normal HSCs to cancer-associated fibroblasts (CAFs). Moreover, our data exposed that HCC cells secreted exosomal miRNA-21 that directly targeted PTEN, leading to activation of PDK1/AKT signaling in HSCs. Activated CAFs further advertised tumor progression by secreting angiogenic cytokines, including VEGF, MMP2, MMP9, bFGF and TGF-. Clinical data indicated that higher level of serum exosomal miRNA-21 was correlated with higher activation of CAFs and higher vessel denseness in HCC individuals. Conclusions Intercellular crosstalk between tumor cells and HSCs was mediated by tumor-derived exosomes that controlled progression of HCC. Our findings offered potential focuses on for prevention and treatment of.
