Exosomes are nanoparticles that are released and received by nearly all cells in the body. They are typically 30-100 nm in size. These extracellular vesicles act as one of our body’s communication systems, delivering important molecular payloads from cell to cell. Each EV’s particular biological function is determined by molecules that reside either on its surface or in its interior.

Exosomes are sometimes called EVs or Secretomes. They produced by signaling cells (some of which are Mesenchymal Stem Cells) upon specific physiological or environmental cues, which contain a precision payload capable of modulating the phenotype of target cells.
