Exosomes are extracellular vesicles ranging from 30 to 150 nm in diameter that are released from various types of cells, including tumor cells. They can induce apoptosis, modulate the immune system, and function as biomarkers for diagnosis. In addition, as an important component of cell-to-cell communication, exosomes can regulate the tumor microenvironment and are involved in the development, progression, and metastasis processes of numerous cancers^1,2.
