Research on some genes of tooth germ initiation.

对小鼠牙胚根形成阶段进行原位杂交研究。我们的研究结果显示，Pgk1和ATPase 6在牙胚中有mRNA表达。在根形成初期，Pgk1在内上皮和外上皮中表达mRNA。然后，Pgk1 mRNA在根形成后期的成釉细胞和成牙细胞中表达。ATPase6的表达结果与Pgk1相似，在根形成初期在内上皮和外上皮均有mRNA表达。然后，ATPase6 mRNA在根形成后期的成釉细胞、外上皮细胞和成牙细胞中表达。

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.
