胚胎

Hence, potentially viable embryos will be discarded upon screening a single blastomere.

因此，有可能对单个卵裂球的基因筛选导致一个有活力的胚胎被丢弃。

The repeated detection of single blastomere of untransferred embryos verified the PGD results, and further indicated that our PGD technique of ACH was relatively stable and reliable.

通过对未移植胚胎的单卵裂球的重复检测，验证了PGD的结果，进一步说明了我们开发的ACH的PGD技术是较稳定、可靠的。

Fluorescence in situ hybridization was performed to detect the existence of HBV DNA in the blastomere by using the biotinylated probe.

废弃的胚胎卵裂球经激光打孔，活检2～4个卵裂球细胞，利用生物素标记的探针，应用荧光原位杂交技术检测HBV感染情况。

In this study, we found interesting two-cell stage embryos, which had a monopolar spindle in one blastomere and a bipolar spindle in the other during the second mitosis in a batch subjected to tetraploidization treatment.

在诱导四倍体过程中，我们发现了有趣的二细胞期胚胎现象，在第二次有丝分期间，它的一个分裂球中有一个单极纺锤体，二另一个有一个双极纺锤体。

3The sensitivity of organisms on toxin differs at different development stage: in common, the embryo before blastula was more sensitive to toxin.

3生物不同发育阶段对毒物的敏感性不同：一般来说原肠期之前的胚胎对毒物较敏感。

Short time delay dont result in preimplantation embryos death, but impacted blastula rate of pronucleus embryos.

短时间滞留不会引起着床前胚胎死亡，但却使原核胚发育到囊胚能力显著下降。3。

Based on Experiment two, froze-thaw embryos were cultured to the stage of blastula and thentransferred to uterus in experiment three.

试验三：以试验二为基础，将各组冷冻解冻胚胎培养发育至囊胚期进行子宫移植。

The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.

桑椹胚形成于囊胚之前且处于胚胎期内的球形裂球群，由受精卵细胞的分裂而成

GV oocytes with normal shape were not obtained in the group which was stored at 20℃ for 24 h and at 25℃ for 14 h; A blastula rates (64%) of all groups in average was gotten in culturing 2-cell in vitro, and there is no significant difference in temperature and time of storage. After transplantating some of the 2-cell embryos which were obtained from GV oocytes stored at 15'C for 8 h, normal infant mice could be obtained.

在20℃下保存24h和25℃下保存14h时，难以获得形态正常的GV期卵；体外受精获得的2细胞期胚经体外培养，总体上有64%的胚胎发育至扩张囊胚，未见有保存温度和保存时间的显著影响，且利用在15℃保存8h后的GV卵获得2细胞期胚的移植获得正常新生小鼠。

Double-walled stage of the embryo succeeding the blastula.

囊胚发育之后的双层胚胎。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
