Results: The expression of both mRNA and protein of c-myc were obvious in the bud and cap stages,while decreased in the bell stage, then increased in ameloblast and dentinoblast when dentin formation. The expressions of c-myc were stronger in mesenchymal cells than in epithelial cells. The expression and distribution of c-myc mRNA is consistent with that of c-myc protein.

结果：c-myc mRNA及蛋白的表达在蕾状和帽状期明显，钟状期减弱，而牙体组织形成期成釉细胞、成牙本质细胞及间充质牙乳头细胞表达又增强。c-myc蛋白表达和分布与c-myc mRNA转录基本一致。

RESULTS: CaB was not detected during early odontogenesis from the dental lamina to the late c ap stage .Small amount of the protein first appeared in ameloblast and some of dif ferenting cells in the surface of dental papilla in early bell stage. As to late bell stage, the cytoplasm of ameloblasts and odontoblasts with secreted dentin was all stained strongly, as well as some of n uclei.

结果：人牙胚蕾、帽状期成釉器无CaB的表达；钟状早期成釉器的内釉细胞及部分牙乳头表面处于分化状态的细胞弱阳性染色；钟状晚期成釉器的成釉细胞、成牙本质细胞及部分胞核呈现强阳性染色。

Results showed that β-catenin was positive expression in stellate reticulum,inner dental epithelium,and dental sac at cup stage,in inner dental epithelium,dental papilla cell,and cell nucleus at early bell stage,in cervical loop and cusp cell membrane at late bell stage,and in ameloblast and odontoblast cell at amelogenesis stage.

结果表明，帽状期在星网层、内釉上皮、牙囊均为细胞核阳性表达；钟状早期在内釉上皮、牙乳头细胞核阳性表达；钟状晚期在颈环、牙尖细胞膜阳性表达；成釉期早期在成釉质细胞、成牙本质细胞阳性表达；成釉期晚期均阴性表达。

Then Tom and Bob went to the sideboard where the decanter was, and mixed a glass of bitters and handed it to him, and he held it in his hand and waited till Toms and Bobs was mixed, and then they bowed and said,"Our duty to you, sir, and madam;" and THEY bowed the least bit in the world and said thank you, and so they drank, all three, and Bob and Tom poured a spoonful of water on the sugar and the mite of whisky or apple brandy in the bottom of their tumblers, and give it to me and Buck, and we drank to the old people too.
