- AIM: To study the expression of Msx2 and BMP-4 in the cap stage of the mouse tooth germ and the relation with the mouse tooth morphogenesis. 目的 :探讨Msx2、BMP - 4基因在小鼠牙胚发育帽状期的表达及其与牙胚形态发育的关系。
- METHODS: The expression patterns of Msx2 and BMP-4 in the cap stage of the mouse tooth germ were studied by in situ hybridization. 方法 :利用原位杂交的方法观察小鼠牙胚帽状期Msx2、BMP - 4基因的表达方式 ;

- Method: bFGF expression was exmined with immmunohistochemical technique in bud stage,cap stage and bell stage of human tooth germ from aborted embryo of 7,8,10 and 14 weeks. 方法 :选择胎龄分别为 7、8、10、14周自愿终止妊娠的新鲜人胚胎各 4例 ,制作牙胚切片 ,将蕾状期、帽状期和钟状期牙胚切片 ,做免疫组化检测。
- Up to cap stage, bell stage and tooth tissue secretory stage, the expression of OPN was wider and more extensive than that of BSP. Especially during tooth tissue secretory stage, OPN was strongly positive in all tooth germ cells and bones. 在帽状期、钟状期及牙体硬组织(牙冠、牙根)分泌形成期,OPN的表达范围及强度高于BSP,尤其在牙体硬组织形成期,OPN在牙胚各类细胞及骨组织中均呈强阳性表达。

- Methods: PCD was detected by TdT-mediated dUTP nick end labelling (TUNEL) in different stages of tooth development of SD rat. Results: The TUNEL showed that there was consistent PCD present in the bud stage, cap stage and bell stage. 方法：采用原位末端标记法（TUNEL法）及HE染色技术，对纯系SD大鼠牙胚发育不同阶段的程序性细胞死亡现象进行观察。 结果：在牙齿发育的蕾状期、帽状期、钟状期均有程序性细胞死亡现象。
