胚胎发育

These results indicated that CB is necessary for synchronization in spindle formation in both oocyte and primary spermatocyte, and that synchronization may be required for subsequent embryo development.

这一结果表明CB的处理可以使精母细胞与卵母细胞同步形成MI纺锤体，使其发育同步，这可能对以后胚胎的发育具有重要作用。

It is reported that KAP-1 related transcription regulation complexes exert functions essen-tial for spermiogenesis and early embryo development. This regulation is one pattern of epigenetic regulations.

KAP-1参与形成的复合体在精细胞发育、胚胎早期发育等生理过程中发挥重要的调控作用，这种调控属于表观遗传调控范畴。

Exoscopic Describing the type of development of a plant embryo in which the apex of the sporophyte develops from the outer cell formed by the first division of the zygote , the inner cell giving rise to the foot.

外向的：指一种植物胚胎的发育类型，其孢子体的顶端由受精卵的第一次分裂的外层细胞发育而来，内层细胞形成根。

Probably the first peak of ABA was the factor for the ignition of embryo development, and the second peak runs in coincidence with the rapid development of the embryo and may inhibit the viviparity of American ginseng seed.

ABA第一个高峰的出现可能正是引起西洋参种胚起始发育的因子，第二个高峰则与种胚的快速发育一致，可能起着防止胚胎过早萌发的作用。

BACKGROUND: Embryonic stem cells develop from early blastular inner cell mass. Under proper condition, ESCs can maintain undifferentiated state in vitro, normal diploid nuclear type, and proliferative potential. In addition, ESCs possess multi-directional differentiation capacity and can differentiate into all sorts of cells of three germ layers.

背景：胚胎干细胞来源于发育早期囊胚的内细胞团，适当条件下能在体外维持未分化状态、正常二倍体核型及无限增殖能力，且具有多向分化潜能，能够发育分化成机体3个胚层的所有类型细胞。

It was shown that the two family proteins are involved in the cardiogenesis process or cardiac disease. Northern blot analysis and whole-embryo antibody staining indicate that ZNF382 expression is restricted largely to heart tissue suggesting a potential role in heart development and function. In contrast, Irxl mRNA was expressed strongly in kidney, brain, and lung. Whether hIrx1 is involved in heart development like mIrxl and cIrxl remains to be investigated.

Northern杂交和胚胎原位抗体染色结果表明ZNF382主要在成体心脏组织表达，ZNF382可能在心脏发育和心脏功能的发挥中起重要作用，相对比，Irx1 mRNA强烈在肾脏，脑和肺组织表达，人类的Irx1基因是否像小鼠和鸡的Irx1基因一样，也参与心脏的发育还需要做进一步的研究。

The expression profiles analysis of 25 genes belonging to 8 types in different development periods of Y35 somatic embry showed, genes involved in transcription, signal transduction, cell fate, substance transport, cell and development regulation were active at early and middle stages of somatic embryogenesis, while at the stage of cotyledonary embryo maturation, the high level-expressed genes were mainly those related to storage protein, maturation and defense.

通过半定量和Real-Time PCR技术，对WRKY和MAPKK等8类25个差异表达基因在Y35体细胞胚不同发育时期的表达分析显示，转录、信号转导、细胞生长分裂、细胞命运、物质转运和多数发育调节相关基因在体细胞胚胎发生的早期或中期比较活跃，而进入子叶胚成熟后期则主要是储藏蛋白、成熟和防御相关基因大量表达。

Thus gp130 is the common signal transduction molecule. Gp130 molecule expresses universally on many tissues including immune system, hemapoietic system, and nerve system. Gp130 has an essential role in the function and regulation of the above systems, especially in the development of hemapoietic system. The signal transduced by gp130 is necessary during the differentiation and proliferation of hemapoietic cells. It is evidenced that the embryo of gp130 gene-knockout mouse was dead due to a serious impediment of the development of hemapoietic system.

Gp130在人体组织细胞上广泛性表达，介导和调节机体的免疫、造血以及神经系统的生理功能，尤其是在造血系统的发育过程中，具有极其重要的作用，动物实验表明，敲除小鼠的gp130分子基因可以使其在胚胎的早期阶段产生严重的造血系统障碍，最终导致流产，由此表明在造血细胞的分化、发育和生物学行为中，gp130介导的信号是必不可少的。
