摘要:

背景:碱性成纤维细胞生长因子是具有多功能的细胞生长因子,对来源于中胚层及神经外胚层的细胞有明显的促进增殖作用。
目的:观察碱性成纤维细胞生长因子对体外培养人牙周膜细胞的作用。
方法:将第5代人牙周膜细胞,以1×108 L-1的浓度分别接种到96孔板,随机分成4组,分别加入含0,1,10,100 μg/L的碱性成纤维细胞生长因子、体积分数为15%胎牛血清的α-MEM培养基进行培养。在第1,3,5,7天测定细胞的增殖情况,在第1,7天检测碱性磷酸酶活性。
结果与结论:4组之间人牙周膜细胞增殖情况的差异有显著性意义(F=6.586,P=0.024),随着碱性成纤维细胞生长因子质量浓度的增大,吸光度值均增大,其中100 μg/L碱性成纤维细胞生长因子组的吸光度值均大于其他组(P < 0.05);碱性成纤维细胞生长因子各组的碱性磷酸酶活性均低于对照组(P=0.000),浓度越大,活性越低(P < 0.05)。结果显示碱性成纤维细胞生长因子在1-100 μg/L范围内质量浓度越高,促进人牙周膜细胞增殖和抑制碱性磷酸酶活性的作用越强。

Abstract:

BACKGROUND: Basic fibroblast growth factor is a pluripotent cytokine that can promote the proliferation of mesodermal and neuroectodermal cells.
OBJECTIVE: To observe the effect of basic fibroblast growth factor in human periodontal ligament cells cultured in vitro.
METHODS: Human periodontal ligament cells at passage 5 were inoculated into the 96-well plates at the density of 1×108/L, and were randomly divided into four groups. The cells were cultured in α-MEM containing 15% fetal bovine serum and 0, 1, 10, 100 μg/L basic fibroblast growth factor, respectively. At 1, 3, 5, 7 days of the culture, the cell proliferation was determined, and the activity of alkaline phosphates was detected at 1 and 7 days.
RESULTS AND CONCLUSION: There were significant differences in the proliferation of human periodontal ligament cells among the four groups (F=6.586, P=0.024). As the increase of the basic fibroblast growth factor concentrations, the absorbance value was gradually increased and reached the peak in 100 μg/L basic fibroblast growth factor group (P < 0.05). The alkaline phosphatase activity in basic fibroblast growth factor groups was lower than that of the control group (P=0.000), the higher the concentration was, the lower activity was (P < 0.05). Results show that basic fibroblast growth factor can promote the proliferation of human periodontal ligament cells and inhibit the activity of alkaline phosphatase, and the effect is concentration-dependent.

Key words: periodontal ligament, cells, fibroblast growth factor 2, cell proliferation
