Platelet-derived nanovesicles for hemostasis without release of pro-inflammatory cytokines

Abstract

Natural platelet-derived nanovesicles with a vacant core were prepared by hypotonic sonication. The nanovesicles efficiently formed platelet-like aggregates using membrane protein in the presence of thrombin and calcium chloride without a notable release of pro-inflammatory cytokines. These natural and biocompatible platelet-derived nanovesicles have great potential as biomaterials for inflammation-free injectable hemostasis.
