卵裂细胞

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。

This process of cell division or cleavage in the zygote is called segmentation.

这种细胞的分裂或受精卵的分裂称为卵裂。

This site provides image materials on fish development, including time-lapse recordings illustrate the morphogenesis of zebrafish embryos, from early cleavage to organ rudiment formation, fish epidermal cell movies, 3-D films of zebrafish gastrulation, and much more.

该网站提供有关鱼类发育的图像材料，包括阐明斑马鱼胚胎形态发生（从早期卵裂到器官初期形成）的时间间隔录象、鱼类表皮细胞影片、斑马鱼原肠胚形成的三维影片，等等。

Experiment Ⅴ: Mouse polyploid embryos were produced by electrofusing 2-cell blastomeres successionally.

实验六、通过2-细胞卵裂球交换制作2n／4n嵌合小鼠胚胎，对这种胚胎的发育能力进行了评价。

Methods The rate of the activated egg and the rate of lysed+dead egg were compared at different ages of ooeytes: 13, 16, 19, 22h with the electrical parameters of 0.6Kv/cm, 80μs 22h electrical poises (2p).

在0.6kV/cm、80μs、2个电脉冲(2p)下，比较了注射人绒毛膜促性腺激素后13、16、19、22h卵母细胞的激活率、碎裂＋死亡率。

The results were as follows:The first, there were significantly differences percent between 0.6μg/mlgroups and other three groups (0.2μg/ml groups, 0.4μg/ml groups and 0.8μg/mlgroups) in 2 hour groups; and there were significantly differences between0.4μg/ml groups and other three groups in 4 hour groups; and there weresignificantly differences between 0.6μg/ml groups and other three groups in 6hour groups; and there were significantly differences between 0.4μg/ml groupsand other three groups in 8 hour groups on the metaphases (P＜0.05), in theexperiment of the effect on the mouse 4- cell embryo stage single blastomere ofcolchicine with different concentrations and duration, by x~2 statistical analysis.

实验结果如下：1、在确定秋水仙素不同处理浓度和时间对小鼠4-细胞期胚胎单卵裂球中期分裂相数影响的实验中，经统计分析，阻断培养2小时组中0.6μg／ml浓度组与其他三组差异显著(0.2μg／ml组、0.4μg／ml组和0.8μg／ml组)；阻断培养4小时组中0.4μg／ml浓度组与其他三组差异显著；阻断培养6小时组中0.6μg／ml浓度组与其他三组差异显著；阻断培养8小时组中0.4μg／ml浓度组与其他三组差异显著(P＜0.05)。

By three days after injection, the number of embryos which had cleaved to the 2-cell stage was 0 with round spermatids and mree(17.6%) with elongated spermatids.

结果在培养的 3 d中，ROSI的卵子没有发生卵裂，＆ ELSI的卵子中有 3个服至 2细胞期O7.6O）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
