They can transport their loaded substances to the recipient cells and play a role of biology. Exosomal miRNAs play important roles in the occurrence and development of tumors, and they are closely related to the tumor growth, metastasis, drug resistance and immune regulation. Exosomes and exosomal miRNAs can be served as reference indexes for tumor metastasis and prognosis, which provide new targets for tumor therapy.
