The potential utilization of platelet-derived extracellular vesicles in clinical treatment

This is the authors' abstract. We don't add key points for this paper.

Platelet-derived extracellular vesicles (PEVs) are released by platelets in the blood circulation, which carry a rich bio-molecular cargo influential in intercellular communications. PEVs can enter the lymph, bone marrow, and synovial fluid as nano-sized particles, while platelets cannot cross tissue barriers. Considering the advantages of PEVs such as low immunogenicity, high regulation of signal transduction, and easy obtainment, PEVs may be promising therapeutic tools for medical applications. The exceptional functional roles played by PEVs explain the recent interest in exploring new cell-free therapies that could address needs in angiogenesis, regenerative medicine, and targeted drug delivery. The review takes a critical look at the main advances of PEVs in the treatment of diseases by presenting the latest knowledge from the performed studies, in order to enhance the further translation of the PEVs research into feasible therapeutic applications.

Platelet-derived extracellular vesicles hold potential as cell-free therapies for angiogenesis, regenerative medicine, and targeted drug delivery due to their low immunogenicity and ability to cross tissue barriers.
