查询词典 pronucleus

Lamin A gene cDNA lacking of 150 basyls at the end of the eleventh extron was cloned into pcDNA3.1 carrier, and the recombinant plasmid pcDNA3.1-mutant LMNA cDNA was injected into the male pronucleus of mouse zygotes, then the zytotes was replanted into the oviducts of pseudopregnant mice.

实验方法：将缺失了第11外显子末端150个碱基的LMNA基因cDNA克隆到pcDNA3.1载体，应用原核显微注射方法将线性化的pcDNA3.1-mutant LMNA注射到小鼠受精卵的雄原核，再将注射后的受精卵移植至假孕鼠的输卵管。

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.

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。

Fluorescence in situ hybridization was carried out to confirm the integration of HBV DNA into male pronucleus and its replication with cell division in embryonic development.(Reverse transcriptase polymerase chain reaction,RT-PCR) and immunofluoresence assay were performed to observe the expression of the HBV gene in two-cell stage.

材料与方法：成熟雄鼠麻醉后双侧睾丸注射经脂质体DOSPER包裹的HBV质粒，手术后雄鼠与超排雌鼠合笼交配，用荧光原位杂变(Fluorescence in situ hybridization，FISH)分别检测单细胞胚和二细胞胚间期核中HBV DNA的存在与复制，用逆转录聚含酶链反应(Reverse transcriptase-polymerase chain reaction，RT-PCR)和免疫荧光方法检测HBV基因在二细胞胚胎中的表达。

Recombinant expression vector k14/c-myc-paav was constructed bearing the mouse c-Myc cDNA derived by the skin specific human keratin 14 promoter, then the linear vector was microinjected into the two pronucleus of the C57BL/6 fertilized eggs to produce transgenic mice.256 microinjected eggs were transferred, 6 of the foster mothers were pregnant and 44 adult mice were produced, two of them were positive transgenic mice confirmed by PCR and Southern blot analysis, transgenic rate was about 4%.

以CMV-PAAV载体为基础载体，以皮肤特异人K14（人角蛋白14）基因启动子替换原质粒中的CMV启动子后，在其多克隆位点区依次插入鼠c-Myc基因的cDNA序列和gfp基因的编码序列，构建了高效表达c-Myc基因的真核表达载体。通过双原核显微注射技术，将线性化的载体DNA注入到C57BL/6小鼠受精卵的两个原核中，然后将注射后状态良好的胚胎移植到代孕鼠的输卵管中，共移植了256枚受精卵，6只受体怀孕，最终获得44只成年小鼠。
