摘要:

目的通过研究碱性成纤维细胞生长因子(bFGF)对人牙周膜细胞(PDLC)多配体蛋白聚糖-4 mRNA水平表达的影响,探讨bFGF在人PDLC迁移中的作用。方法收集正畸拔除的12~18岁青少年健康前磨牙68颗,体外原代培养人PDLC,用外源性bFGF刺激细胞,培养24、48、72 h后,采用实时荧光定量聚合酶链反应检测细胞内多配体蛋白聚糖-4 mRNA的表达。结果培养24 h时,实验组多配体蛋白聚糖-4 mRNA表达量显著高于对照组(P<0.01),其中1.0 ng·mL-1组升高最为显著;培养48 h时,1.0 ng·mL-1组多配体蛋白聚糖-4 mRNA表达量高于对照组(P<0.05);培养72 h时,1.0 ng·mL-1组多配体蛋白聚糖-4 mRNA表达量低于对照组(P<0.05)。结论初期bFGF促进人PDLC内多配体蛋白聚糖-4 mRNA合成,但随着时间的延长,bFGF抑制多配体蛋白聚糖-4 mRNA合成,这种改变是促进PDLC迁移过程中一个重要的调节因素。

Abstract:

Objective To study the effect of basic fibroblast growth factor(bFGF) on the gene expression of syndecan- 4 by human periodontal ligament cell(PDLC) in culture, and discuss the effect of bFGF on human PDLC proliferation and migration. Methods 68 adolescent(12-18 years old) health premolar were collected, which were extracted for orthodontic reason. Human PDLC were cultured and stimulated by exogenous bFGF. After cultured 24, 48, 72 h, gene expression of syndecan-4 was detected by SYBR green quantitative real time polymerase chain reaction. Results The mRNA expression of syndecan-4 in 24 h group increased markedly than that in control group(P<0.01), expecially in 1.0 ng·mL-1 group. 1.0 ng·mL-1 group in 48 h higher than that control group(P<0.05). 1.0 ng·mL-1 group in 72 h compared with control group was lower(P<0.05). Conclusion The mRNA expression of syndecan-4 was increased by bFGF at the beginning, but the expression was decreased with the time. The expression of such changes may be one of the important factors which participate in the migration process of PDLC.
