Extracellular Vesicles (EVs) are nanometer sized particles endogenously released by cells.
EVs contain membrane proteins and lipids as well as cytoplasm components whose patterns depend on parental cells.
Extracellular Vesicles are now recognized as active players participating in homeostasis and disease which act as biological effectors in physiological processes.
Recent discoveries suggest that EVs have protective and reparative properties in tissue regeneration, representing thereby an important therapeutic tool. EVs may display regenerative properties accounting for the paracrine effect of cell therapies.
