Objective: To observe the relationship between the odontoblast process and the dentinal tubules. 目的:观察成牙本质细胞突在牙本质小管中的分布。
All these lines have been proven for their capability of differentiation into odontoblast, dentin, pulp, or cementum in vivo. 这些不同来源的牙齿干细胞，在囓齿动物移植实验中，可以分化为牙本质母细胞，进而形成牙本质，或分化成为牙髓结构，或形成牙骨质。
Histochemical study indicated that most of amelogenin stayed in enamel matrix and others diffused to dentin,dental tube and odontoblast layer. 组织化学研究结果显示在釉质形成期,釉质蛋白大部分留在釉基质层,也有一部分向牙本质内扩散到牙本质、牙本质小管以及造牙本质细胞层内。

Dentin matrix protein 1 (DMP1) is expressed in both pulp and odontoblast cells and deletion of the Dmp1 gene leads to defects in odontogenesis and mineralization. 牙本质基质蛋白-1（DMP1）在牙髓和成牙本质细胞中均有表达，Dmp1基因缺失可导致牙齿发育和矿化障碍。
In the previous researches, it is always demanded to separate the differentiated stages of DPSC which are always identified by the molecular markers in odontoblast. 在牙髓干细胞的研究过程中,常需要根据成牙本质细胞分子标记物的表达来判断牙髓干细胞的分化进程。
