Therapeutic Application of Extracellular Vesicles Derived from Mesenchymal Stem Cells in Domestic Animals

Extracellular vesicles (EVs) secreted by mesenchymal stem cells (MSCs) have recently been described in human and veterinary medicine and great interest is directed toward them for their therapeutic potential. EVs are vesicles produced and secreted by Mesenchymal Stem Cells (MSCs) that possess the same anti-inflammatory and regenerative properties as the cells themselves but seem safer for clinical applications because of lower immunogenicity and lower size. MSCs that produce EVs can be derived from adult tissues such as bone marrow or adipose tissue or from fetal adnexa such as amniotic membrane and Wharton’s jelly. This manuscript gives a summary of the current description of composition, characteristics, sources, and function of EVs, focusing especially on their therapeutic applications in veterinary medicine to date. Knowledge of these features and the steps taken to date will help researchers and veterinary practitioners discover new approaches to regenerative medicine that are ever closer to being achievable.
