摘要:
目的 探究可注射型富血小板纤维蛋白(injectable platelet-rich fibrin, iPRF)对体外培养的人脐静脉内皮细胞(human umbilical vein endothelial cells, HUVECs)成血管分化能力的影响。方法 CCK-8实验检测HUVECs增殖能力并筛选最佳浓度的可注射型富血小板纤维蛋白提取液(injectable platelet-rich fibrin extract, iPRFe);划痕实验和小管形成实验分别检测HUVECs迁移能力和成血管分化能力;实时定量PCR检测成血管相关基因的mRNA表达。结果 0.4 mg/mL浓度的iPRFe促进HUVECs增殖效果最佳;iPRFe对HUVECs迁移和小管形成有显著的促进作用,还能明显提高血管生成素(angiogenin, ANG)、C-X-C基序趋化因子受体4(C-X-C motif chemokine receptor 4, CXCR4)、血小板衍生生长因子受体A(platelet-derived growth factor receptor A, PDGFRA)和血管内皮生长因子(vascular endothelial growth factor, VEGF)的表达水平。结论 iPRF可以促进HUVECs增殖、迁移和成血管能力,有望成为用于牙髓再生的新材料。

Abstract:
Objective To explore the effect of injectable platelet-rich fibrin(iPRF) on angiogenesis of human umbilical vein endothelial cells(HUVECs) in vitro. Methods The proliferation ability of HUVECs was detected by the Cell Counting Kit-8(CCK-8) and the optimal concentration of iPRF extract(iPRFe) was selected. The migration ability and angiogenesis capacity of HUVECs were detected by scratch assay and tube formation assay, respectively. Real-time quantitative polymerase chain reaction(RT-qPCR) was performed to evaluate the mRNA expressions of angiogenic genes. Results The iPRFe at 0.4 mg/mL had the best effect on the proliferation of HUVECs. The iPRFe significantly promoted migration and tube formation of HUVECs, and significantly increased the expressions of angiogenin(ANG), C-X-C motif chemokine receptor 4(CXCR4), platelet-derived growth factor receptor A(PDGFRA), and vascular endothelial growth factor(VEGF). Conclusion The iPRF can promote the proliferation, migration and angiogenesis of HUVECs, and may be used as a novel material for pulp regeneration.
