来自口腔组织的混合细胞群可能较纯干细胞用于再生。因此,本研究旨在探讨与牙槽成骨细胞相比口腔结缔组织来源的混合细胞的成骨潜能。

从牙槽骨、牙周膜和牙龈中分离出原代细胞。通过集落形成、生长能力和流式细胞术进行表征。细胞进行成骨分化后,使用Western印迹、qPCR阵列和基质矿化和碱性磷酸酶定量筛选大量成骨标记物。

结果显示,与未诱导的牙周混合细胞相比,来自牙龈的非诱导混合细胞显示出更高的集落形成效率,但增殖减少,两组具有相似表面标记物。成骨诱导后,所有细胞群均单独表达具有明显活化的下游效应物的受体。诱导牙周混合细胞的基因表达与牙槽成骨细胞类似,但在牙龈混合细胞中有不同的调节。后者成骨分化方面,基质矿化和碱性磷酸酶活性较差,而这可在牙周混合细胞和成骨细胞中观察到。

综上所述,该研究表明,来自牙周韧带而非牙龈的混合细胞在体外具有固有的成骨能力。牙周细胞不需要进一步的干细胞富集进行骨再生。
