Following 72 h co-culture, desquamate, sporozoites, trophozoites, meronts, microgametocytes, macrogametocytes, zygote, thin-wall oocyst, and thick-wall oocyst appeared orderly. Between the 60th and 72th hour, many oocysts emerged. Inoculated by the C. parvum -infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.

在感染后72 h内，隐孢子虫出现连续发育阶段，包括脱囊、子孢子、裂殖子、裂殖体、滋养体、配子体、合子、薄壁卵囊和厚壁卵囊，在60～72 h内形成卵囊；用感染48 h的细胞培养上清接种于免疫抑制小鼠， 10 d后有隐孢子虫卵囊排出。

Haplont A haploid organism that represents the vegetative stage in life cycles in which diploidy is restricted to the zygote.

单倍性生物：是一个单倍体或生物体，该生物体体现二倍性仅限于合子的生活史中的营养阶段。

It takes about 0.5 h for a pollen tube from germination to arrive at the micropyle. About 0.5 h after pollination, the pollen tube releases two sperms into one synergid. At 0.5-2.5 h after pollination, the egg cell fuses with one sperm to form a zygote. About 10.0 h after pollination, the division of the zygote begins. The duration of the zygote lasts about 2.5-10.0 h. However, one sperm nucleus fuses with two polar nuclei at 1.0-3.0 h after pollination, and 5.0 h after pollination the primary endosperm nucleus begins to divide.

水稻受精过程经历的时间表如下：授粉后，花粉在柱头萌发；花粉萌发至花粉管进入珠孔大约需要0.5小时；授粉后0.5小时左右，花粉管进入一个助细胞，释放精子；授粉后0.5-2.5小时，精卵融合形成合子；授粉后约10.0小时，合子第1次分裂，合子期为授粉后2.5-10.0小时；授粉后1.0-3.0小时，精核与两极核融合；授粉后约5.0小时，初生胚乳核分裂。

The zygote replicates itself, then we have many copies of zygote, they are called the stem cells.

受精卵自我复制，我们将会有很多分裂的受精卵，他们被称为干细胞。

Polysomes change in number as "few-many-few-many" during the development of the egg, early zygote stage, zygote at dormancy, zygote in prophase of mitosis and two-celled proembryo in sugar beet, which indicates that such changes in metabolism as "low-high-low-high" activity may relate to the transformation from gametophyte to sporophyte generation.

根据上述结果可以得出，栽培甜菜从卵细胞成熟→合子初期→合子休眠期→合子分裂前期→二细胞原胚的超微结构变化中多聚核糖体的变化最为显著，表现为&少→多→少→多&的数量变化过程，反映出细胞代谢状态也经历了&弱→强→弱→强&的变化过程，这种变化趋势与配子体世代向孢子体世代转变有关。

The mature egg cell was an inactive cell with only a few polysomes. At the early zygote stage, a large number of ribosomal precursors were produced by the nucleolus, and many polysomes appeared in the cytoplasm, which suggests a high level of metabolism. Zygote at the dormancy stage had a small nucleolus and marked decrease in ribosomes, as shown by a few polysomes, which suggests decreased metabolism. Zygotes in the prophase of mitosis and two-celled proembryo became active again in metabolism, for a prominent nucleolus, high density of ribosomes and increased number of polysomes in the cytoplasm.

结果如下：在成熟卵细胞中多聚核糖体数量不多，且细胞代谢活性较弱；初期合子内，核仁大量合成核糖体前体物质，胞质中多聚核糖体数目众多，细胞代谢活性较强；休眠期合子的核仁变小，胞质中核糖体数量急剧减少，仅有少量多聚核糖体，细胞代谢活性较弱；合子分裂前期和二细胞原胚期，核仁显著，胞质中核糖体的密度增加，出现大量多聚核糖体，细胞代谢活性较强。

To optimize the in vitro culture system of mouse pronuclear zygote and to investigate the effect of FBS, PVA, hLIF on mouse zygote development in vitro, we did four experiments separately.

筛选最佳的小鼠胚胎体外发育培养体系，并进一步探讨不同浓度的FBS、PVA、hLIF对其体外发育的影响，从而为小鼠卵母细胞核移植后重构胚的体外培养提供支持。
