Abstract:

BACKGROUND: Exosome is a nanoscale vesicle body secreted by many kinds of cells, such as stem cells, tumor cells, and cancer stem cells. Exosomes contain a large amount of bioactive molecules that mediate the communication between cells.

OBJECTIVE: To review the correlation between exosomes from different source and tumorigenesis and explore the research trends and directions in the future.

METHODS: PubMed, CNKI, and WanFang databases were retrieved for relevant articles using the keywords of “exosomes, tumors, bone marrow mesenchymal stem cells, caner stem cells, HH signaling pathway” in English and Chinese, respectively. The search time was from January 2015 to June 2019. Finally, 80 literatures, including 27 English articles and 53 Chinese articles, were included for result analysis.

RESULTS AND CONCLUSION: Serum-derived exosomes have a potential in the diagnosis of non-small cell carcinoma, hepatocellular carcinoma, gastric cancer, colon cancer, pancreatic cancer and breast cancer, which may become a potential alternative diagnostic marker for tumor detection. Tumor-derived exosomes can regulate tumors by promoting the growth, proliferation, migration and invasion of tumor cells, regulating immunity and the expression of tumor-related genes and proteins. Exosomes derived from stem cells can promote the invasion and metastasis of tumor cells, which may be achieved through the activation of HH signaling pathway. In addition, exosomes derived from cancer stem cells can enhance the resistance of tumor cells to chemotherapy by promoting the expression of tumor-related drug resistance genes. Exploration on the correlation between cancer stem cell-derived exosomes and drug-resistant genes is likely to discover potential targets for tumor treatments.

Key words: exosomes, tumors, bone marrow mesenchymal stem cells, caner stem cells, HH signaling pathway
