Zygotes are also tested to make sure they are free of the original genetic disease. 有专家会建议说,利用基因匹配技术再生一个好了,这个孩子可以为患病的孩子提供支持。
Conclusion Zygotes and embryo quality can be predicted by morphology of the first polar body. 结论通过卵细胞第一极体形态可预测受精卵及卵裂期胚胎质量。
Post-zygotic self-incompatibility, referred to as an abortion, occurs shortly after fertilization, and is a result of the interaction between the maternal plant and the zygotes. 合子后的子房内自交不亲和能形成合子,但由于自交不亲和通常由单位点控制,合子败育集中发生在受精作用后的很短时间内。
Egg cells, zygotes and proembryos of Allium tuberosum Roxb were isolated using an enzymatic digestion. 用同样的方法也成功地分离了韭菜的合子和早期原胚。

By microinjection techniques on germ nucleus of zygotes hMR-1 gene were injected into zygotes of CD-1? 首先利用受精卵原核的显微注射技术,将MR1基因显微注射至CD-1?
Methods Transgenic mice were created by microinjection of α-MHC-HB-EGF construct into male pronucleus of the zygotes. 方法构建α-MHC-HB-EGF表达载体,将目的片段注射到受精卵的雄原核中,使其发育成携带有HB-EGF的转基因小鼠。
Tetraploidy was induced by inhibition of the first and the second polar bodies in normal diploid zygotes. 药物直接抑制二倍体马氏珠母贝受精卵第一极体和第二极体的释放,诱导四倍体;
The receptors for transforming exogenous DNA is zygotes; 外源DNA转化的受体应为合子;
The receptor mechanism for exogenous DNA transformation probably is that exogenous DNA combines randomly with zygotes in plasmic state. 外源DNA转化受体的机制可能是外源DNA与处于原生质体状态的合子的随机融合。
Isolation of egg cells and zygotes in Oryza sativa 水稻卵细胞与合子的分离
Objective: To study the mechanism of human oocyte development and fertilization by detecting the ( distribution) and translocation of classical protein kinase C ( PKC) in human oocytes and zygotes. 目的通过检测经典型蛋白激酶C(CPKC)在人各期卵母细胞及受精卵中分布及转位,探讨CPKC在人卵母细胞成熟及受精中的作用机制。
Objective: To study the preservation and development of mouse zygotes after being frozen and thawed. 目的:研究小鼠受精卵冷冻解冻后的发育效果。

The isolation of vigorous egg cells and zygotes provides an opportunity to study fertilization mechanism. 3. 卵细胞与合子的大量分离为高等植物受精机理的研究创造了条件。
Different types of zygotes were used for detailed comparative study. 2. 并进一步对不同类型合子的离体发育前途进行了比较研究。
It was also reported by PKB/ Akt pathway, which regulate embryonic development in mouse zygotes. 另有报道PKB通过PKB/Akt途径,在小鼠受精卵早期调节胚胎发育。
Zygotes moved quicker than egg cells, suggesting the surface charges of the zygote increased after fertilization. 在实验中,合子的移动速度比卵细胞快,暗示受精后,合子所带的表面电荷增加。
After thawing, the rates of survival, fertilization/ activation, embryonic development of oocytes/ zygotes and changes in the cytoskeleton and ploidy were observed. 复苏后统计卵母细胞/合子的成活率、受精率/激活率和胚胎发育率,并观察细胞骨架和倍型变化。
