摘要
目的研究香烟提取物对原代培养的牙周成纤维细胞中MMP-8表达的影响。方法取原代培养的牙周成纤维细胞,分别设立空白对照组及香烟提取物干预组,培养24h后,分别收集细胞裂解液,进行Western blot检测,并通过灰度值比较分析MMP-8的表达情况。结果经分析发现,香烟提取物干预组的MMP-8的表达明显高于空白对照组,二者之间有统计学差异。结论香烟提取物干预牙周成纤维细胞后,可使MMP-8的表达升高,从而说明吸烟可能通过上调MMP-8的表达加重牙周组织的破坏。
Objective To investigate the expression of MMP-8 in periodontal fibroblast cells after affected by CSE. Method The periodontal fibroblast cells were classified into control and CSE interfering groups.After incubation for 24h,cell lysates were collected for western blot analyse. Result In CSE interfering groups, the expression of MMP-8 was higher than control groups. Conclusion CSE can upregulate the expression of MMP-8 which may destroy the periodontal tissues.
