The ameloblast differentiation is controlled by sequential epithelial-mesenchymal interactions during tooth morphogenesis.

成釉细胞的分化是由牙齿形态发生期上皮和间充质的一系列相互作用调控的。

This finding corresponded to the immunohistochemical data showing the presence of phosphorylated forms of p38, c-Jun N-terminal kinase, and extracellular signal-regulated kinase during ameloblast differentiation.

这个发现与免疫组织化学数据相符，显示在成釉细胞的分化过程中，p38磷酸化形式，c-Jun氨基端激酶以及细胞外信号调节激酶均有表达。

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: Ameloblastin mRNA was negative under microscope in the ameloblast proliferate differentiation period, it showed weakly positive expression in intra-cellular and new-birth enamel matrix in secrete initial stage while it showed strongly positive expression in intra-cellular and new-birth enamel matrix when it came to secretion phase.

结果：釉鞘蛋白mRNA在成釉细胞增殖分化期表达为阴性，分泌初期细胞内及新生釉基质中开始出现弱阳性表达；至分泌期，细胞内及新生釉基质中均呈强阳性表达。

Aim:To observe the amitosis and asymmetric division in subcultured PC12 cells, and to explore the role of amitosis and asymmetric division in tumorigenesis, tumor cell pleomorphism and differentiation.

目的 ：观察传代培养的PC12细胞的无丝分裂和不对称分裂，探讨其在肿瘤发生、肿瘤细胞多形性和细胞分化中的意义。

Amitosis and asymmetric division play an important role in PC12 cell pleomorphism. The asymmetric division possesses important significance in tumorigenesis and differentiation.

无丝分裂和不对称分裂是PC12细胞多形性形成的主要原因，肿瘤细胞无丝分裂及其不对称性对肿瘤发生及肿瘤细胞的分化具有重要意义。

On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

Human amnion is able induce mouse ES cells to differentiate into epidermal like stem cells, the differentiation ratio is about 90％.

人羊膜在体外可诱导小鼠ES细胞向表皮样干细胞分化，其分化率约为90％左右。

In this new architectural plan the Garden of Golgotha came to be at the centre of the new city.

Aelia 是高举他自己，并在此城内朝拜罗马诸神。

The continuous nature of peat accumulation means that terrestrial coaly rocks may provide a higher resolution and more complete record of base-level change than the time-equivalent shallow-marine strata, thus enabling the identification of highfrequency cycles that are not recorded in themarine strata.

泥炭积累的持续性质的手段，陆地coaly岩石可提供较高的分辨率和更完整的记录基准面变化的影响时，相当于浅海阶层，从而使确定的高频周期，不记录在themarine 阶层。
