After 16 weeks growth, continuous and intact ameloblast, enamel, dentin, odontoblast was found.

生长16周的人牙胚，已经形成连续完整的成釉质细胞，牙釉质、牙本质和成牙本质细胞层。

Results It was demonstrated that β-TrCP expressed in oral epithelium, tooth bud, mesenchymal cell cytoplasm of ameloblast and edontoblast of different stage of tooth development.

结果β-TrCP在胚胎10.5、13.5、14.5、16.5、18.5d的小鼠牙胚上皮层与间充质层，以及出生后0、3、6d的小鼠成釉细胞与成牙本质细胞胞浆呈特征性表达。

The results suggest that Smad4,one of the intracellular downstream molecules of TGF-β superfamily,and an inductive signal mediating epithelial-mesenchymal interaction,may regulate the differentiation of ameloblast and odontoblast cells,and modulate dentinogenesis and amelogenesis.

结论首次观察到Smad4信号分子在人牙胚发育过程中的表达，Smad4作为TGF-β超家族细胞内信号分子，可能参与上皮间充质的相互作用，同时也参与成釉细胞和成牙本质细胞的分化以及牙釉质和牙本质的形成。

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.

利用原位杂交技术、免疫组织化学技术检测SD大鼠牙胚发育不同时期c-myc mRNA转录及蛋白的表达情况。

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。

You are OK amice of a curl lop, or comb two beautiful hair of ear border backward case, plunge into high otherwise remove a horsetail, green vigor is not had can hold back; Also can be after the head dish into bob, put apart a few hair on the temples wave at will hang down, show mature female oomph; If does late banquet hair style, small a long hair is best still " embryo is sent ", the beautiful type that can make all sorts of beauty sends sample.

你可以将一头卷发披肩垂下，或将耳际的两缕秀发向后梳起，不然干脆高高地扎起一个马尾，青春活力无可阻挡；也可以在脑后盘成发髻，留出几缕鬓发随意飘垂，展现成熟女性的魅力；倘若做晚宴发型，微卷长发还是最好的"胚发"，可以做出各种美丽的花式发样。

In the later period of ripeness, the protein bodies were extruded and filled with amyloplast.

成熟后期，蛋白质体因胚乳细胞中大小淀粉体的充实被挤成片层结构而填充在淀粉体缝隙中。

The ultrastructures of amyloplast development and proliferation in maize endosperm cell were observed using the method of glutaraldehyde-osmium tetroxide fixation.
