Extracellular vesicles show promise for cancer theranostics

Extracellular vesicles (EVs) are naturally occurring small membrane vesicles (30–150 nm), protected by a lipid bilayer, that originate from endosomes and are formed through the fusion of the plasma membrane with multivesicular endosomes (MVEs), and subsequently exocytosed (1). The roles of EVs are numerous and could be important in cancer biology and disease (2). A recent research topic highlights extracellular vesicles addressing the processes that they regulate in cancer and their potential therapeutic value.
