摘要:

目的:探讨碱性成纤维细胞生长因子及其受体在人牙髓中表达和意义。方法:用免疫组化方法检测碱性成纤维细胞生长因子及其受体在人牙髓中的表达。结果:碱性成纤维细胞生长因子在成牙本质细胞层强阳性表达, 在牙髓其它细胞和血管内皮细胞阳性表达;碱性成纤维细胞生长因子受体在成牙本质细胞层弱阳性表达,牙髓其它细胞为阴性。结论:碱性成纤维细胞生长因子及其受体在反应性及修复性牙本质形成过程中可能起重要作用。

Abstract:

Objective:The aim of this study was to observe the expression and the effect of basic fibroblast growth factors (bFGFs) and their receptors (bFGFRs) in human dental pulps.Methods:By collecting sound human third molars and premolars, the paraffin sample of tooth slice were prepared with ordinary methods. The bFGFs and bFGFRof human dental pulpswere examined by using SABC immunohistochemical technique.Results:Strong specific staining for bFGF was observed in the odontoblasts of healthy te- eth, and positive stainingwas found in other pulp cells and vascular endothelial cells. The faint signal of bFGFRwas detected only in the odontoblasts, and negative in other pulp cells.Conclusion:The expression of basic fibroblast growth factor (bFGF) and its receptor (bFGFR) in human dental pulp suggests that bFGF and its receptormay play an important role in the reactionary and re- pairable dentinnogenesis.
