配母细胞

Then the matured oocytes and capacitation sperm were transferred into 4 recipients fallopians .

初步表明卵母细胞的成熟培养有利于提高配子移植的成功率。

To elucidate the relationship of GSE expression and gametogenesis, mRNA (0.5μg each) from mouse testis and ovary on different postnatal days were analyzed by RT-PCR with specific primers for GSE cDNA. The GSE mRNA in the testis of mouse was first detected at Day 14 postpartum, when cells at mid-pachytene are likely to appear.

为了阐明GSE表达与配子发生的关系，从0～49日龄小鼠睾丸和卵巢中提取mRNA（每样品0.5μg，将其与特定的GSE cDNA引物进行RT-PCR反应，分析的结果发现，GSE mRNA在出生后第14天的小鼠睾丸中首先被检测到，这一时间正是中粗线期精母细胞很可能出现的时期。

The gametophyte is derived from the product of a reduction division in the megaspore mother cell.

该配子体是由大孢子母细胞进行减数分裂而来。

Although the megagametophyte formed and even the double fertilization had been finished 70 days after pollination at normal temperature, the megasporogenesis had not yet been finished at low temperature.

低温(12-18℃)处理的蝴蝶兰，授粉50d开始分化胚珠原基、60 d胚囊处于大孢子母细胞时期，比常温(20-25℃)下的推迟10-15 d；授粉70 d，常温下的蝴蝶兰植株已完成雌配子体发育和双受精，而低温处理的蝴蝶兰仍未完成大孢子的发生过程。

In response to a cue that is not well understood, some parasites differentiate into male and female gametocytes,which are the forms taken up by the mosquito and which can live quiescently in the bloodstream for weeks.

以回应不是好了解的暗示，有些寄生生物区分入男性和女性配子母细胞，是蚊子占去的形式，并且在血液可能居住淡静地几星期。

These mainly involve the periodic change of ribosome den- sity,the dedifferentiation and redifferentiation of both plastid and mitochondrion during the process of meiosis.

在这个过程中，小抱子母细胞经减数分裂产生大致相同的4个减数抱子，并逐渐发育成雄配子体。

The archegonial initials could be distinguished from the perip heral cells at the micropyle end of the female gametophyte before the completion of the wall formation where the cell wall had reached the center of the gametop h yte.

雌配子体中游离核之间细胞壁还未完全形成时，在其近珠孔端表面可看到颈卵器母细胞发生。

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

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
