Figure 2. . Cells secreted bodies into the extracellular space are called secretome, which contains soluble proteins, free nucleic acid, lipids and extracellular vesicles.

The EVs can be divided into apoptotic bodies, microparticles and exosomes. Microparticles are also indicated with other names: nanoparticles, microvesicles, shedding vesicles or shedding bodies, exovesicles, secretory vesicles and oncosomes. Exosomes contains growth factors, cytokines and functional RNA.

EV: Extracellular vesicle.
