Exosomes are produced by multivesicular bodies, they are extracellular lipid nano-vesicles carrying a variety of bioactive substances, containing lipids, RNA, DNA and proteins. Exosomes produced by tumor cells carry important information about tumor cells. Exosomes produced by hepatocellular carcinoma can participate in the formation of a microenvironment suitable for the proliferation, growth, invasion, metastasis and drug resistance of tumor cells.Meanwhile, circulating exosomes can be used as non-invasive biomarkers for early diagnosis of tumors and as drug delivery vectors for treatment.This review summarizes the characteristics of exosomes in the growth, invasion and metastasis, immune escape, and drug resistance biology of hepatocellular carcinoma, as well as the potential clinical application of early detection and treatment. Key words: Exosomes; Biological markers; Carcinoma, hepatocellular; Therapeutic potential
