摘要: 目的:观察骨形态发生蛋白-2和(或)碱性成纤维细胞生长因子转染的大鼠骨髓干细胞(BMSCs)和牙胚细胞在体外混合培养对牙本质基质蛋白1、成釉蛋白、Ⅰ型胶原蛋白、同源异型盒基因1的影响。方法:采用实时定量PCR和Western blot的方法,检测 BMP-2和(或)bFGF对成牙基因的影响。结果:对照组、bFGF组、BMP-2组、bFGF/BMP-2组四组间,AMBN、COLLAGEN-Ⅰ、DLX1、DMP1基因在mRNA和蛋白水平表达量上存在明显差异(P<0.05)。结论:BMP2和bFGF有一定的协同交互作用,BMP2/bFGF/BMSCs/牙胚细胞可以作为构建组织工程牙的种子细胞。

Abstract: Objective: To observe the bone morphogenetic protein -2 (BMP-2) and (or) basic fibroblast growth factor (bFGF) transfected rat bone marrow stem cells (BMSCs) and germ mixed culture cells in vitro effects on dentin matrix protein 1 (DMP1), ameloblastin (AMBN), Ⅰ collagen (collagen-Ⅰ), homeobox gene 1 (DLX1)'s. Methods: From gene expression and protein levels by real-time quantitative PCR and Western blot to determine the level of BMP-2 and (or) the impact of bFGF on four genes. Results: The control group, bFGF group, BMP-2 group and bFGF / BMP-2 group among the four groups, AMBN, COLLAGEN-Ⅰ, DLX1, DMP1 genes were significantly different (P<0.05) in the expression of mRNA and protein levels. Conclusion: BMP2 and bFGF have synergistic interaction, BMP2 / bFGF / BMSCs / germ cells can be constructed as seed cells for tissue engineering of teeth.
