摘要:

背景:多项实验表明牙胚组织在不同的时间点有不同的基因发挥作用,共同促进牙胚发育。
目的:观察牙本质基质蛋白1、成釉蛋白、Ⅰ型胶原蛋白和同源异型盒基因1在大鼠牙胚细胞体外培养的不同时间的表达。
方法:对体外培养后第1,3,6天的牙胚细胞提取RNA,反转录后采用实时定量PCR的方法检测牙本质基质蛋白1、成釉蛋白、Ⅰ型胶原蛋白和同源异型盒基因1mRNA相对表达水平的变化。
结果与结论:牙胚细胞中牙本质基质蛋白1、成釉蛋白和Ⅰ型胶原蛋白mRNA的表达随培养时间的延长而增加,在培养3 d时达到峰值(P < 0.05),而同源异型盒基因1 mRNA的表达随培养时间的延长而下降(P < 0.05)。

Abstract:

BACKGROUND: Some studies have indicated that different genes in tooth germ tissue play a role at different time, contributing to tooth germ development.
OBJECTIVE: To observe the expressions of dentin matrix protein 1, enamel protein, collagen I and homeobox gene 1 at different stage of in vitro culture of tooth germ cells.
METHODS: RNA from tooth germ cells was extracted at days 1, 3, 6 of in vitro culture. After reverse transcription, real-time quantitative PCR detection was adopted to measure relative expression of dentin matrix protein 1, enamel protein, collagen I and homeobox gene 1 mRNA.
RESULTS AND CONCLUSION: Dentin matrix protein 1, enamel protein, and collagen I mRNA expressions increased with culture time, and reached the peak at day 3 (P < 0.05), whereas homeobox gene 1 mRNA decreased with culture time (P < 0.05).
