J Endod:根尖复合物和冠髓做为干细胞来源应用于牙髓牙本质再生的评估

2019-12-19 lishiting MedSci原创

这篇研究的目的是为了比较人未发育成熟恒牙的根尖复合物(apical complex cells [ACCs])和冠髓(dental pulp stem cells [DPSCs])来源干细胞的干性和分化潜力,以确定更适合用于牙髓牙本质再生的干细胞来源。

这篇研究的目的是为了比较人未发育成熟恒牙的根尖复合物(apical complex cells [ACCs])和冠髓(dental pulp stem cells [DPSCs])来源干细胞的干性和分化潜力,以确定更适合用于牙髓牙本质再生的干细胞来源。

研究从13颗人的未发育成熟恒牙中提取并体外培养ACC和DPSC。评估ACC和DPSC的增殖能力和克隆能力。采用流式细胞仪检测ACC和DPSC的干细胞标志物。采用实时定量聚合酶链式反应和组织化学染色评估ACC和DPSC的成脂和成骨潜力。采用大孔双相磷酸钙作为载体将ACC和DPSC植入免疫缺陷小鼠皮下。通过HE染色和免疫组织化学染色鉴定新形成组织的组织形态学特征。通过碱性磷酸酶定量分析ALP,通过实时定量聚合酶链式反应检测BSP, DSPP, POSTN和ColXII的表达情况。

结果显示,ACCs和DPSCs展示出相似的细胞增殖潜力和细胞克隆能力。并且ACCs和DPSCs之间的间充质干细胞标志物比例相似。体外研究显示,ACCs和DPSCs均具有成脂和成骨分化的潜力。体内研究显示,使用大孔双相磷酸钙颗粒作为载体使ACCs和DPSCs形成无定形硬组织。ACCs和DPSCs组无定形硬组织的含量与组织形态特征相似。在ACC移植组中,能够观察到Col XII表达阳性的牙周膜样组织的形成,而DPSC移植组中未检测到。

结论:ACCs和DPSCs展示出相似的干性、增殖率和硬组织形成能力。2者之间显著的差异为ACCs具有形成牙周膜样纤维组织的能力,表明根尖复合物与冠髓相比含有不同的干细胞系。考虑牙髓牙本质复合物的再生,冠髓基于细胞的同源性以及良好的成骨/成牙本质分化潜力更适合作为干细胞的来源。
