受精卵发育 meaning in English
fertilized egg development
Examples
- Monozygotic twins, on the other hand, arise from the same fertilized egg .
同卵双生子则是由同一个受精卵发育而成的。 - Sporogonium the sporophyte generation in mosses and liverworts . it develops from the zygote and comprises the foot , seta , and capsule . the sporogonium is parasitic on the gametophyte generation
孢子体：为苔藓和地钱的孢子体世代具有。由受精卵发育而来，包括基足、柄和孢蒴。孢子体是寄生在配子体上的。 - To find bsp proteins and its related prot eins important roles in fertilization and the development of the zygote , we clone the full - length cdna which is related to bsp genes and named hbrp ( human bsp - related proteins )
为了进一步发现和研究bsp及其相关蛋白在受精及受精卵发育中的重要作用，我们克隆出人与bsp蛋白相关基因的cdna ，将其命名为hbrp ( humanbsp - relatedprotein ) 。 - Using the hprt gene as a positive control , our result suggested that both the testis tissue and the male embryos from which sry transcription can be detected failed to yield any positive results of xist . female embryos at the pronucleus stage and 2 - cell failed to produce any positive result of sry and xist too . while since the 4 - cells period , xist is constantly transcribed until blastocyst stages
然后利用实验一确定的pcr条件，以hprt为阳性对照，用巢式rt - pcr对小鼠早期胚胎进行xist基因的转录分析，结果发现，转录sry基因的睾丸组织以及雄性胚胎，从受精卵发育到囊胚的过程中，基本上不转录xist基因；不转录sry基因的雌性卵母细胞和雌性胚胎，从出现原核开始，到发育至2 -细胞期的过程中， xist基因一直不转录，但是，从4 -细胞期开始，一直到孵化前囊胚阶段，雌性胚胎都转录xist基因。
