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。

This suggests that CaHIRA plays a role in the early embryo development and the late stages. The different expression characters of hira gene in these fish species may be related to the different reproduction models. The research on Drosophila has indicated hira gene related to sperm nucleus decondensation during fertilization. The high expression of hira gene before fertilization is prepared for the sperm nucleus decondensation and the formation of male prenucleus because colored crucian carp is bisexual reproduction. However, the sperm nucleus is not decondensated during the fertilization and is only to activate egg nucleus in gynogenetic gibel carp.
在彩鲫中，从未受精卵到胚胎发育的各个时期均可检测到表达，但表达量发生明显变化，受精后表达量迅速下降，直到原肠胚期表达量有所上升，并一直保持到出苗。hira基因在两亲缘种成熟卵子受精前后表达情况不同，可能与两种鱼不同的生殖方式有关。

Oocyte samples from one group were collected to detect the presence and integration of HBV DNA within cells and chromosomes using PCR, Southern blot, dot hybridization and fluorescence in situ hybridization. The female animals from another group were mated with their normal males, respectively. Their zygotes, 2-cell embryos were collected to detect the integration of HBV DNA in the female pronuclei of zygotes and the replication and expression of HBV genes in the 2-cell embryos using FISH, RT-PCR and immunofluoresence assay.(1) PCR detected positive bands in the tested oocyte samples fromgoldon hamster and mice. Southern blot revealed clear hybridization signals in PCR products.
研究用金黄地鼠和小鼠建立实验动物模型：将卵巢内注射HBV DNA的实验动物分成两组，一组注射后进行超排卵，收集卵巢和输卵管的卵母细胞，用PCR、Southern杂交，斑点杂交和荧光原位杂交(fluorescence in situ hybridization、FISH)检测HBV在卵母细胞内的存在和染色体上的整合；另一组超排雌鼠与正常雄鼠合笼，收集受精卵和2-细胞胚，用FISH、RT-PCR和免疫荧光检测技术分别研究HBV基因在受精卵雌原核上的整合以及在2-细胞胚中的复制与表达。

amphiblastula：两囊幼虫
在钙质海绵中,形成中空的两囊幼虫(amphiblastula),在寻常海绵纲中形成实心的实胚幼虫(parenchymula). 钙质海绵,例如白枝海绵或毛壶的受精卵在母体的中胶层中发育,当受精卵经细胞分裂形成16个细胞时,构成动物极的为8个小细胞,

elytron：背鳞
(2)a.多毛类鳞沙蚕体背左右两行排列的扁平板,系疣足背触须的变态,总称为背鳞(elytron). 雌体背面背鳞之间成为贮藏受精卵的育房. 容易脱落,亦易再生. b.覆盖于昆虫、特别是鳞翅目昆虫翅表面的毛状或叶状的微小扁平物. 发生学上与刚毛相同,
-
fertilized ovum：受精卵
两个原核逐渐在细胞中部靠拢,核膜随即消失,染色体混合,形成二倍体的受精卵(fertilized ovum),又称合子(zygote). 受精的意义在于:①受精使卵子的缓慢代射转入代谢旺盛,从而启动细胞不断地分裂;②精子与卵子的结合,恢复了二倍体,维持物种的稳定性;
-
zygote：接合子
称为接合子(zygote)的受精卵,在著床(midation)前的两周内,可成单细胞的孪生或多胎子,又可再合成一个胎儿. 那麼,如果妇人妊娠之初,胎儿即为人灵形成,孪生胎儿之两个「人灵」的生出如何讲解?而再合成(recombination)之现象更难以解释了:另一个「人灵」到何处去了?
-
zygote：合体
再者,胚胎又是相继从受精卵和结合体(zygote)演变而来,假如胚胎是人,难道受精卵和结合体不算是人?若是,则不但怀孕两星期后的堕胎是谋杀,连卵细胞受精后才去打掉它的避孕方法也是谋杀!为了要弥补上述的漏洞,有些赞成堕胎的人便修改立场,

monozygotic twins：单卵孪生
双胎(twins)也称孪生,发生率约新生儿的1%. 2、单卵孪生,由一个受精卵发育为两个胚胎,由于此种孪生的遗传基因完全一样,故两者性别一致、相貌和生理特征也极相似. 形成单卵孪生(monozygotic twins)的原因可有三种:

monozygotic twins：单卵双生子
习惯上,人们用克隆表示由同一物种具有相同基因型的两个或多个个体组成的群体. 所以,从同一受精卵分裂而来的单卵双生子(monozygotic twins)便属于同一克隆. 细胞学上,克隆是指由同一个祖细胞...
