结果］计算得到猪卵母细胞透明带的弹性模量为(1.43±0.29)×10^4Pa。

To understand the factors effecting on mammalian early embryo development, we carried out the study through 3 points of view, oocytes, zona and embryo culture in vitro.

本研究分别从卵母细胞、透明带以及胚胎体外培养三个角度来探讨影响哺乳动物早期胚胎体外发育的因素。

The main research achievements on oogenesis and embryogenesis in mammals are described in this review,including the resumption of meiotic division;activation of MⅡ oocyte;development of parthenogenetic,gynogenetic,androgenetic and reconstituted embryos;and the genetic and reproductive potentials of chromosomes within the first and the second polar body.

本研究将论述哺乳动物卵子发生和胚胎发生的最新研究进展，包括：减数分列的启动， MⅡ期卵母细胞的激活，孤雌胚、雌核胚、雄核胚和重组胚的发育以及第一与第二极体染色体的遗传和生殖潜力。

目的研究丁内酯-Ⅰ对小鼠卵母细胞体外成熟及成熟动力学的影响。

We observed changes of GV chromatin configurations in porcine, caprine and bovine oocytes from follicles of different sizes and degrees of atresia and during maturation in vivo and in vitro, using a new method for preparation of GV samples.

本项目发明了一种特殊的卵母细胞生发泡标本制备技术，能克服脂肪滴等对生发泡染色质构型观察的阻碍；经Hoechst或CMA3染色后可清楚地观察染色质构型的变化。

Oocytes were cultured in Oocytes Maturation medium with EGF and IGF-1 alone or combinedly at different concentration.

研究了在培养液中添加不同浓度的EGF﹑IGF-1 以及EGF 联合IGF-1 对山羊有腔卵母细胞体外成熟的影响。

In conclusion, either electrofusion parameter or developmental stage of donor embryos have a significant effect on the efficiency of NT, NT embryos require different concentration of serum at their different development stages.

结果表明，电融合参数和供体胚胎的发育阶段以及受体卵母细胞的状态对NT效果有显著影响，在NT胚胎的不同发育阶段采用不同的血清种类和浓度可提高其胚胎发育能力。

This one mode pays close attention to network credence foundation of the businessman very much.
