摘要: 目的 观察改良型富血小板纤维蛋白(advanced- platelet-rich fibrin, A-PRF)对人骨髓间充质细胞(human bone marrow mesenchymal cells, hBMMCs)生物学性能的影响。方法 对hBMMCs进行多向分化能力鉴定,扫描电镜及人生长因子阵列膜检测A-PRF微观结构及分子构成,CCK-8检测A-PRF对hBMMCs增殖的影响,划痕实验检测A-PRF对hBMMCs迁移的影响,通过碱性磷酸酶活性检测及茜素红染色检测不同浓度A-PRF对hBMMCs矿化能力的影响。结果 扫描电镜结果显示A-PRF为三维网状结构;人生长因子阵列膜检测发现A-PRF含有40多种细胞因子,并含有巨噬细胞集落刺激因子受体(macrophage colony stimulating factor receptor, M-CSF-R)及人神经生长因子β(β-nerve growth factor, β-NGF);体外实验可见10% A-PRF可以提高细胞增殖(P<0.05)和迁移能力,同时可促进hBMMCs形成钙沉积和碱性磷酸酶活性表达(P<0.05)。结论 A-PRF对hBMMCs的成骨分化、增殖和迁移有促进作用,其中10%的A-PRF促进作用更为明显。因此,A-PRF对hBMMCs具有良好的细胞生物学效应,可为临床选择A-PRF促进骨组织再生提供初步实验依据。

Abstract: Objective The aim of this study was to investigate the cytobiological effects of advanced-platelet rich fibrin (A-PRF) on cells from human bone marrow mesenchyme (hBMMCs) in vitro. Methods hBMMCs were identified as adipogenic and osteogenic differentiation. A-PRF was observed under a scanning electron microscope and its growth factor was detected by human growth factor antibody array-membrane. CCK-8 and scratch tests were used to detect the effect of A-PRF on the proliferation and migration of hBMMCs at different concentrations. Alkaline phosphatase activity and alizarin red staining were used to detect the effect of different concentrations of A-PRF on the mineralization ability of hBMMCs. Results SEM showed that A-PRF is a three-dimensional network containing more than 40 cytokines, among which macrophage colony stimulating factor and human nerve growth factor had not been reported. 10% A-PRF increased cell proliferation and migration ability (P<0.05), but also promoted calcium deposition and ALP of hBMMCs (P<0.05). Conclusion A-PRF improved the osteogenic differentiation of hBMMCs and the proliferation and migration, and 10% A-PRF achieved the most obvious promotion effect. The favorable cytobiological effects of A-PRF on hBMMCs might serve as the basis for A-PRF applications in bone regeneration.
