在胚胎阶段

Caghira gene is expressed in the unfertilized eggs and all stages of embryogenesis and the quantity of Caghira gene expression didn\'t changeobviously, which could be inferred that hira gene had an effect on gynogenetic development of gibel carp.

在银鲫的未受精卵中和胚胎发育不同阶段均可以检测到少量的转录产物，表达量未检测到明显变化，表明hira基因可能在银鲫雌核发育过程中发挥一定作用。

With IF failures, most often the embryo produced doesn't hae the genetic to deelop beyond a certain stage, explains Dr. Steen Ory, president of the American Society for Reproductie Medicine who is in priate practice in Margate, Fla.

在失败的IF中，最常见的是生产的胚胎由于不具有遗传而不能发育到一定阶段，美国生殖医学协会**Steen Ory博士解释说，他同时在Margate， Fla从事私人业务。

The result suggests PACAP/GHRH has an important role in embryos and larvae, especially in neurula appearance stage.

结果表明，自卵受精后，均有GHRH／PACAP的表达，且在神经胚期表达量增高（约5倍）；提示PACAP在斜带石斑鱼胚胎和仔鱼发育过程中具有重要作用，尤其是神经出现阶段。

However, the ubiquitous expression of AmphiLysC in non-digestive tissues such as ovaries, testes, notochord, gill and muscle suggests that it may also play a non-digestive role like antibacterial defense.

但是，在文昌鱼成体其他组织如卵巢、精巢、脊索、鳃和肌肉中也检测到了AmphiLysC的表达，同时原位杂交结果也表明，AmphiLysC在文昌鱼胚胎发育的不同阶段（从2个细胞到2天幼虫）都有广泛的表达。

To observe the ontogenetic expression pattern and its tissue-specific distribution of gene transcripts in different stages of C57BL/6J mouse development.

观察2810430M08Rik基因转录产物在C57BL/6J小鼠个体发育过程中的表达模式，分析其在小鼠胚胎期、新生期及成年期各阶段的组织和细胞特异性分布特征。

The aim of this study was to analyze the relative expression patterns of mRNA for IGFs in different development stage of preimplanted ovine embryos by using reverse transcription-polymerase chain reaction.

本研究主要在mRNA水平上检测了IGFs在绵羊植入前不同发育阶段胚胎中的表达规律。

In fish and amphibia, the transition from maternal gene transcription to zygotic transcription happens during the time of midblastula formation, this stage is named by midblastula transition, at this period, embryo cell cycle composition changes, it is the first time to G1 time appearance, the cell cycle timelimit lengthens and the cell division synchronism loses, the large quantities of zygotic gene transcription starts.

鱼类和两栖类由母型调控向合子型调控过渡发生在中囊胚形成阶段，称为中囊胚过渡(midblastula transition，MBT)，胚胎细胞周期时相的组成在此期间发生变化，首次出现G1期，周期时限延长，细胞分裂的同步性丧失，大批合子型基因活化转录也在此时开始。

A new method for enucleating MⅡ nucleus in mouse and rat was induced; Living births were obtained from IVF of mouse oocytes reconstructed by transfer of metaphase Ⅱ chromosomes. For the interspecies nuclear transfer between mouse and rabbit, the reconstructed embryos could develop into blasocyst in vitro.

在不同品系小鼠卵母细胞核质交换移植中将电融合的重构卵进行IVF，经胚胎移植后顺利产仔；在异种核移植方面，小鼠核与兔卵母细胞的异种重构胚在体外培养条件下发育至囊胚阶段。

The proportion of embryos developing to the blastocyst stage was not significantly different between two systems, however the static microdevice environments produced significantly more morulas than did control groups.

胚胎发育成囊胚阶段在两个系统之比率并无明显差异，然而在静态微装置环境比对照组产生明显较多桑葚体。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
