Exosomes are 30-150 nm tiny vesicles secreted by most cell types in vivo and in vitro. They are found in all body fluids including plasma, serum, saliva, urine, amniotic fluid, malignant ascite fluids, and cultured medium of cell cultures. They are also found in the interstitial space. Exosomes contain various molecular constituents of their cell of origin, including proteins and RNA. Evidence has shown that exosomes act as many different roles and functions including eradication of obsolete molecules, intercellular communication, antigen presentation, dissemination of oncogenes from tumor cells, and spread of pathogens such as prions and viruses from one cell to another.
