Dent Mater J:羟基磷灰石复合镁纤维材料的骨诱导潜力:一项体内和体外研究

2019-07-21 lishiting MedSci原创

尽管羟基磷灰石纤维(HAf)作为合成骨成分的替代品已得到充分肯定,但材料如果具有更快的促进骨再生能力将会更好。因此,这篇研究的目的是为了评估HAf 与镁复合(Mg-HAf)后对骨再生的影响。

尽管羟基磷灰石纤维(HAf)作为合成骨成分的替代品已得到充分肯定,但材料如果具有更快的促进骨再生能力将会更好。因此,这篇研究的目的是为了评估HAf 与镁复合(Mg-HAf)后对骨再生的影响。

体外结果显示,Mg-HAf培养下的骨髓细胞成骨分化相关基因表达水平明显高于单独培养于HAf的细胞。此外,研究还评估了仅使用HAf(对照)或5.7 mol% Mg-HAf对Japanese white rabbits颅骨的影响。Micro-CT和组织学结果显示,对照和Mg-HAf组之间存在显著性差异。在4和8周,Mg-HAf组新骨形成的骨量和比例均明显高于对照组(p<0.05);并且Mg-HAf组新形成的骨组织比对照组更加成熟。

结论:这些结果表明,Mg-HAf能够增强成骨分化相关基因的表达并且能够快速促进骨形成和成熟。
