OBJECTIVE
This research is aimed at investigating how high glucose affects the proliferation and apoptosis in periodontal ligament stem cells (PDLSCs) in the presence of TNF-.
METHODS
PDLSCs obtained from periodontal healthy permanent teeth were treated under either high-glucose condition (30 mmol/L, G30 group) or normal glucose condition (5.6 mmol/L, G5.6 group) in the presence or absence of TNF-. . .
RESULTS
CCK-8 assay showed that high glucose exacerbated TNF-. . . . . .
CONCLUSION
High glucose exacerbates TNF--induced proliferative inhibition in human periodontal ligament stem cells through the upregulation and activation of TNF receptor 1. Inhibition of intracellular ROS expression by vitamin C partially rescues PDLSCs in terms of cell proliferation..
目的
本研究旨在探讨在存在肿瘤坏死因子-α（TNF-α）的情况下，高糖如何影响牙周膜干细胞（PDLSCs）的增殖和凋亡。
方法
从牙周健康恒牙获取的PDLSCs在存在或不存在TNF-α的情况下，于高糖条件（30 mmol/L，G30组）或正常糖条件（5.6 mmol/L，G5.6组）下进行处理。
结果
CCK-8检测显示高糖加剧了TNF-α……
结论
高糖通过上调和激活肿瘤坏死因子受体1加剧了TNF-α诱导的人牙周膜干细胞增殖抑制。维生素C对细胞内活性氧表达的抑制在细胞增殖方面部分挽救了PDLSCs。
