Platelet gels (PG) are new topical single-donor blood products which are attracting great interest in regenerative medicine. They are obtained by mixing a platelet-rich plasma fraction with thrombin to generate a fibrin gel enriched in platelet growth factors (GF). The type of thrombin preparation may affect PG reproducibility. We have determined the impact of 14.6% (v/v) ethanol-stabilized thrombin (EHT) on the release of GF by platelets. Various ratios of EHT and platelet concentrates were mixed to obtain from 2.43 to 7.96% ethanol concentration. Platelet-derived growth factor-AB (PDGF-AB), transforming growth factor-ß1 (TGF-ß1), vascular endothelium growth factor (VEGF), epidermal growth factor (EGF), and insulin-like growth factor-1 (IGF-1) were assessed at 5, 120, and 300 min after PG formation. Protein profiles of thrombin and PG releasates were analyzed by SDS-PAGE. The amount of PDGF-AB, TGF-ß1, and VEGF released per platelet decreased significantly (p <0.05) with increasing ethanol concentrations but, however, not that of EGF. IGF-1 content was stable, consistent with its presence mostly in plasma. SDS-PAGE indicated that ethanol did not affect fibrin formation. In conclusion, ethanol has a significant impact on the amount of GF released by platelets and should be strictly controlled to standardize PG and optimize clinical benefits.
