查询词典 spermatocyte

It indicated that mTSARG3 was involved in the meiosis by which spermatogenous cell differentiated to spermatocyte. We established mosue cryptorchidism model and disolated total RNA at different days after operation to perform RT-PCR.

为研究mTSARG3基因在精子发生中的调节作用，我们分离了小鼠不同发育阶段的睾丸总RNA进行半定量RT-PCR检测，结果显示mTSARG3基因在出生小鼠1周即有表达，在第3周时明显增高，之后保持稳定表达趋势。

For further studying the genetic mechanism of the reproductive isolation phenomenon of interspecific hybrid, paraffin sections of testes from 13 sexually mature male mules (Equus asinus×Equus caballus) and 12 hinnies (Equus caballus×Equus asinus) were prepared, and the samples of Giemsa meiosis and AgNO 3 synaptonemal complexes were observed and compared with spermatocyte meiosis of horse and donkey under light microscope and electronic microscope.

为了进一步探讨种间杂种生殖隔离现象的遗传机理，本研究采用性成熟公骡的睾丸为材料，制备组织切片和减数分裂联会复合体标本进行观察，发现个别性腺发育较好的个体虽然减数分裂存在大量异常，但确有少数精母细胞完成了减数分裂并产生精子。

Cell-cycle synchronization between the donor cell and recipient oocyte determines the embryo development in nuclear transfer. In the present study, we microinjected primary spermatocyte into the perivetelline space of oocyte. 37% pairs fused after electric stimuli and the resulting oocytes were culture for 2 h in MEM with or without CB.

在本研究中，我们将小鼠的初级精母细胞显微注入MI卵母细胞的透明带下，经直流电脉冲作用后有37％的初级精母细胞融入卵母细胞，然后将融合的卵母细胞分成两组在MEM和含有CB的MEM培养液中分别培养，2小时后将在CB培养液中培养的卵母细胞转入正常培养液中。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
