J Orthop Surg Res:巨噬细胞抑制超高分子量聚乙烯(UHMWPE)磨损颗粒诱导的骨溶解过程中成纤维细胞的成骨

2019-03-23 不详 网络

在超高分子量聚乙烯(UHMWPE)修复环境中,受磨损颗粒影响的成纤维细胞具有成骨能力以减少骨质溶解。本研究旨在评估巨噬细胞对UHMWPE磨损颗粒处理的成纤维细胞的成骨能力的影响。通过MTT试验验证不同浓度的UHMWPE(分别为0,0.01,0.1和1 mg/ml)对巨噬细胞增殖的影响,以确定最佳浓度。在UHMWPE颗粒和巨噬细胞上清液的共培养系统中进一步测定成纤维细胞活力。该实验设计为七组:(A)

在超高分子量聚乙烯(UHMWPE)修复环境中,受磨损颗粒影响的成纤维细胞具有成骨能力以减少骨质溶解。本研究旨在评估巨噬细胞对UHMWPE磨损颗粒处理的成纤维细胞的成骨能力的影响。

通过MTT试验验证不同浓度的UHMWPE(分别为0,0.01,0.1和1 mg/ml)对巨噬细胞增殖的影响,以确定最佳浓度。在UHMWPE颗粒和巨噬细胞上清液的共培养系统中进一步测定成纤维细胞活力。该实验设计为七组:(A)仅成纤维细胞; (B)成纤维细胞+ 1 mg/ml UHMWPE颗粒;和(C1-C5)成纤维细胞+ 1/16,1/8,1/4,1/2和1/1的巨噬细胞培养物上清液分别由1mg/ml UHMWPE颗粒和成纤维细胞完全培养基刺激。使用茜素红染色检测钙积累。通过蛋白质印迹和ELISA检测成骨蛋白的表达水平,包括碱性磷酸酶(ALP)和骨钙蛋白(OCN)。

结果显示,由于存活率,0.1mg / ml的浓度被认为是巨噬细胞增殖的最佳浓度,并且在四种浓度中最高。成纤维细胞组中的成纤维细胞存活率在1 mg/ml UHMWPE颗粒刺激的巨噬细胞上清液中比其他组(1:8,1:4,1:2,1:1)更好。与其他组(1/8, 1/16)和成纤维细胞组+ 1mg/ml UHMWPE组相比,1 mg/ml UHMWPE颗粒刺激的成纤维细胞+ 1/4,1/2和1/1上清液中ALP和OCN表达均显著下降(p <0.5)。

总之,该研究结果表明,巨噬细胞可能通过降低在全髋关节置换术中用UHMWPE材料产生的磨损颗粒处理的成纤维细胞的成骨能力而参与植体周围骨溶解。
