Research on some genes of tooth germ initiation.

我们对小鼠牙根形成阶段的原位杂交进行了研究。我们的研究结果表明，Pgk1和ATPase 6在牙胚中都有表达。结果表明，Pgk1基因在生根初期的内、外上皮均有表达。在生根后期，Pgk1在成釉细胞和成牙本质细胞中均有表达。ATPase6的结果与Pgk1相似，在根的初始形成时，内上皮和外上皮均有mRNA表达。在生根后期，ATPase6基因在成釉细胞、外上皮细胞和成牙本质细胞中均有表达。

We study in situ hybridization of the root formation stage of mouse tooth germ. The result of our study shows mRNA expression of Pgk1 and ATPase 6 in tooth germ. As the result of Pgk1, it shows mRNA expression in internal epithelium and outer epithelium at initial root formation. And then, Pgk1 mRNA expression was in the enamelblast and odontoblast cells at the post stage of root formation. The result of ATPase6 similar to Pgk1, it shows mRNA expression in internal epithelium and outer epithelium at initial root formation. And then, ATPase6 mRNA expression was in the enamelblast, outer epithelium, and odontoblast cells at the post stage of root formation.
