J Periodontal Res:牙周膜细胞在RGD合成多肽结合物涂层上的功能和细胞表面特征

2020-05-17 lishiting MedSci原创

这篇研究的目的是为了评估含整联蛋白结合RGD序列(SAK-c[RGDfC], AK-c[RGDfC]和SAK-opn)的3种不同合成结合物对人PDLCs黏附以及随后功能的影响。

牙周膜细胞(PDLCs)是牙周组织愈合与再生的重要来源。适当的细胞黏附是贴壁依赖性细胞存活的关键,也是为了进一步激活细胞内信号以实现重要的细胞功能。这篇研究的目的是为了评估含整联蛋白结合RGD序列(SAK-c[RGDfC], AK-c[RGDfC]和SAK-opn)的3种不同合成结合物对人PDLCs黏附以及随后功能的影响,包括:增殖、迁移、细胞表面分子的反应和成骨分化。

研究通过固相法制备合成肽,并通过硫醚连接将其附着于支链聚合多肽上。通过简单吸附法制作组织培养塑料或电阵列涂层。从24颗拔除的人第三磨牙中分离PDLCs。通过real-time impedimetric xCELLigence SP system检测细胞的黏附和增殖。通过Ibidi? Culture inserts检测细胞迁移。通过流式细胞仪检测细胞表面抗原。通过ALP检测和茜素红S染色评估成骨分化,并通过实时qPCR检测成骨分化相关基因表达。通过real-time Electrical Cell-Substrate Impedance Spectroscopy (ECIS)监测PDLCs的成骨分化和成脂分化。

结果显示,所有3种合成的RGD 肽均能促进PDLC的黏附(P < .05)。当从培养基中去除动物血清时,SAK-c[RGDfC]和AK-c[RGDfC]能够促进细胞黏附(P < .05)。SAK-c[RGDfC]和AK-c[RGDfC]能够增加细胞迁移(P < .05)。在施以1周的处理后,所有3种合成肽均能上调CD105 (1.7- to 2.2-fold)和CD146 (1.3- to 1.5-fold)标志物的表达,并且形成不同的整联模式。在没有成骨诱导的情况下,SAK-c[RGDfC]和AK-c[RGDfC]能够增加ALP活性(1.4-fold)和ARS (1.8- and 2.0-fold),并且所有肽在成骨诱导条件下均能促进矿化。RT-qPCR结果显示,成骨诱导的PDLCs内bone sialoprotein (5.0- to 7.8-fold), osteocalcin (2.3- to 2.7-fold)和ALP (1.9- to 2.3-fold)的基因表达明显上调。ECIS监测结果显示,与成脂诱导或未诱导相比,成骨诱导会产生更强的阻抗(P < .05)。

结论:研究表明,SAK-c[RGDfC]和AK-c[RGDfC]能够促进PDLCs的黏附和迁移,并支持PDLCs的成骨分化。这些环状肽在再生医疗中可作为一种可应用的生物相容性材料。
