摘要/Abstract

摘要： 目的：研究重组人结缔组织生长因子（recombinant connective tissue growth factor, rCTGF）对牙髓细胞（human dental pulp cells,hDPCs）增殖及分化的影响。方法：利用不同浓度（0、1、10、100 ng/mL）rCTGF分别处理牙髓细胞,CCK8法检测牙髓细胞增殖情况;茜素红染色和半定量试验检测细胞矿化结节的形成变化,qRT-PCR测定成牙本质分化相关基因DMP-1、DSPP和OC的表达情况,Western 免疫印迹法测定rCTGF刺激牙髓细胞后,ERK1/2信号通路的磷酸化水平。采用SAS 9.3软件包对数据进行统计学分析。结果：高浓度的rCTGF（100 ng/mL）可以促进牙髓细胞增殖;经矿化诱导后,10 ng/mL rCTGF促进牙髓细胞矿化结节形成的效果最好,钙盐沉积量最明显（P<0.05）,成牙本质分化相关基因DMP-1、DSPP的表达显著上调（P<0.05）。Western 免疫印迹结果显示,10 ng/mL rCTGF刺激牙髓细胞后,p-ERK1/2蛋白的表达升高。结论：rCTGF可能通过激活ERK1/2信号通路,促进牙髓细胞的增殖与分化。

Abstract: PURPOSE: To analyze the effect of recombinant connective tissue growth factor(rCTGF) on proliferation and differentiation of human dental pulp cells(hDPCs). METHODS: Human dental pulp cells were cultured in vitro and treated with rCTGF at different concentrations (0, 1, 10, 100 ng/mL). The proliferation of dental pulp cells was detected by CCK8 assay. The formation of mineralized nodules was determined by alizarin red staining and half-quantitative alizarin Red S assay. qRT-PCR was utilized to detect the expression of odontogenic differentiation related genes DMP-1, DSPP and OC, and the phosphorylation level of ERK1/2 signaling pathway was detected by Western blot. The data were analyzed with SAS 9.3 software package. RESULTS: High concentration of rCTGF(100 ng/mL) could promote proliferation of dental pulp cells. After mineralization induction, 10 g/mL rCTGF had the best effect on promoting the formation of mineralized nodules in dental pulp cells, and calcium ion deposition was the most obvious(P<; 0.05). The expression of odontogenic differentiation related genes DMP-1 and DSPP was significantly up-regulated(P<; 0.05). Western blot results showed that hDPCs stimulated by 10 ng/mL rCTGF could increase the expression of p-ERK1/2. CONCLUSIONS: rCTGF may promote the proliferation and differentiation of human dental pulp cells through activating ERK1/2 signaling pathway.
