摘要: 目的 研究冻干富血小板血浆(freeze-dried platelet-rich plasma, FD-PRP)对人真皮成纤维细胞(human dermal fibroblasts, HDFs)增殖和迁移的作用。方法 分离制备PRP并进行冷冻干燥处理得到FD-PRP,CCK-8法检测人成纤维细胞增殖情况,细胞划痕实验检测人真皮成纤维细胞迁移情况,ELISA检测Ⅰ型胶原蛋白、弹性蛋白的含量。结果 与空白对照组相比,FD-PRP能够显著增加HDFs的增殖以及Ⅰ型胶原蛋白和弹性蛋白表达水平(P<0.05),而与PRP组相比差异无统计学意义(P>0.05)。此外,细胞划痕实验表明,相较于空白组对照组,FD-PRP和PRP处理后的细胞明显向“划痕”处迁移。结论 综上所述,FD-PRP诱导成人真皮纤维细胞增殖和迁移,同时能够刺激Ⅰ型胶原、弹性蛋白的分泌增加。这一研究为FD-PRP日后用于临床治疗各类创面奠定了研究基础。

Abstract: Objective To evaluate the capacity of freeze-dried platelet-rich plasma (FD-PRP) to stimulate the proliferation and migration of human dermal fibroblasts. Methods Freshly isolated PRP was lyophilized to generate FD-PRP. Cell proliferation was quantified using the CCK-8 assay; directional migration was monitored via scratch-wound assays; and the secretion of type Ⅰ collagen and elastin was measured by ELISA. Results Compared to untreated controls, FD-PRP significantly enhanced fibroblast proliferation and increased the secretion of type Ⅰ collagen and elastin (P<0.05). These effects were statistically comparable to those induced by fresh PRP (P>0.05). Scratch-wound assays further revealed that both FD-PRP and fresh PRP markedly enhanced cell migration into the denuded area compared with the controls. Conclusion FD-PRP induces the proliferation and migration of adult dermal fibroblasts and also enhances the secretion of type Ⅰ collagen and elastin. These findings lay a solid experimental foundation for the potential clinical application of FD-PRP in the future treatment of various wound types.
