Platelet-rich plasma preparation using three devices: Implications for platelet activation and platelet growth factor release

Abstract

The three PRP devices enable the preparation of PRP for the release of high concentrations of platelet growth factor, but showed different harvesting capacities for the collection of concentrated platelets. The administration of thrombin for PRP activation resulted in the release of high concentrations of PDGF-AB and TGF-beta but only when PRP had not been activated during the preparation process in vitro.
