摘要: 目的 研究冻干保存方式以及激活时间对富血小板血浆(platelet rich plasma, PRP)生长因子含量的影响。方法 用来自20位健康献血者的血液制备PRP,血小板浓度为(1 031±150.1)×109/L。根据不同保存方式将每份PRP样本分为5组,即新鲜PRP组、冷冻PRP激活组、激活后PRP冷冻组、冻干PRP激活组和激活后PRP冻干组。检测每组PRP中TGF-β1、VEGF、PDGF-BB含量。结果 冻干PRP激活组的TGF-β1和PDGF-BB含量与新鲜PRP组相比差异无统计学意义,而VEGF含量较新鲜PRP组有所升高且差异有统计学意义(P<0.05)。其他3组的TGF-β1和VEGF含量与新鲜PRP组相比差异无统计学意义,而PDGF-BB的差异具有统计学意义。结论 相比较新鲜PRP组,冷冻和冻干保存PRP不影响其三种主要生长因子的释放,而相较冷冻PRP而言,冻干保存对储存条件要求更低,更利于拓展PRP的使用范围。

Abstract: Objective To study the effect of freeze-drying preservation method and activation time on platelet rich plasma (PRP) growth factor (GFs) content. Methods 20 PRPs were collected from healthy blood donors, of which platelet concentration was (1 031±150.1) × 109/L. Each PRP sample is divided into 5 groups, (1) fresh PRP (PRP), (2) frozen PRP activated by calcium gluconate (F-Ca PRP), (3) PRP activated by calcium gluconate followed by freezing (Ca-F PRP), (4) PRP freeze-dried first, then activated by calcium gluconate (FD-Ca PRP), (5) PRP activated by calcium gluconate followed by freeze drying (Ca-FD PRP). The concents of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and platelet-derived growth factor-BB (PDGF-BB) were quantified by ELISA. Results TGF-β1 and PDGF-BB concentrations in FD-Ca PRP were not statistically different from PRP, while the VEGF was elevated and statistically different compared with the PRP. TGF-β1 and VEGF concentrations in the other three groups were not statistically different from PRP, while the differences in PDGF-BB were statistically significant. Conclusion The freezing and freeze-drying on PRP did not affect the concentrations of the three main growth factors from PRP, and compared with freezing on PRP, freeze-drying was less required with storage conditions. It suggested that wider possibilities of freeze-dried PRP for clinical applications.
