Trends Biotechnol. 2021 Jun;39(6):598-612. doi: 10.1016/j.tibtech.2020.10.004. Epub 2020 Nov 4.

Abstract

There is much interest in the use of extracellular vesicles (EVs) as a subcellular therapy for regenerative medicine and drug delivery. Blood-borne platelets represent a source of therapeutic EVs that is so far largely unexplored. Advantages of platelets as a cellular source of EVs include their established clinical value, regulated collection procedures, availability in a concentrated form, propensity to generate EVs, and unique composition and tissue-targeting capacity. This review analyzes the unique potential of platelet-derived (p-) EVs as therapeutic modalities and presents their inherent translational advantages for hemostasis, for regenerative medicine, and as drug-delivery vehicles.

Keywords: drug delivery; exosome; extracellular vesicle; platelet; regeneration.
