Embryo cells display a synchron cleavage rhythm during the cleavage stage, there is almost no gene transactivation, which is regulate and operated by the mRNAs and protein of oocyte.

卵裂阶段的胚胎细胞呈现同步化的分裂节律，鲜有基因转录活动，其发育由源自卵母细胞发生期间合成的蛋白质和mRNAs调控。

The results of this study for the development of mouse embryos provide clues to the mechanism.

本研究的分析结果，可为鼠早期胚胎的发育机理研究提供线索。

Some specific fragments expressed in vivo embryos was found and one of them was selected for further analysis.

The Effect of Some Environmental Factors on the Development of Mouse Embryos In Vitro

不同环境因素对小鼠胚胎体外发育的影响

In contrast, development of CD-1 embryos (835pairs) was significantly lower (25 to 36%).

相反，在835对CD—1胚胎中，仅有25—36％的发育为囊胚。

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。

Clinical Study on treatment of prostatic carcinoma high Intensity hocused ultrasound combined with hormone in the;2. To evaluate the roles and mechanism of IGF-2 on fetal growth and development during late gestation, pregnant ewes and rats were employed to investigate relationship between IGF-2 and metabolites, hormones of pregnant animals and their fetuses.

本文以绵羊、大鼠为实验对象，观测围产期妊娠母羊、胎儿和新生儿血浆IGF-2水平的动态变化及其与其它内分泌激素和代谢物水平之间的相关性，并研究了给予外源性IGF-2片段、葡萄糖、胰岛素和皮质醇对血浆IGF-2、胰岛素和代谢物水平影响，综合分析IGF-2在动物胚胎、新生儿生长发育中的作用，着重探讨IGF-2与营养代谢和内分泌之间的关系以及分泌的调节因素。
