胚胎发育

Our research shows that Arabidopsis ARP6 play a part in these development processes.

拟南芥的胚胎发育是一个复杂的基因调控过程，到目前为止，已经发现了不下于200个基因在胚胎发育过程中起作用。

哺乳动物配子和早期胚胎细胞融合技术在研究卵子和早期胚胎发育中的细胞质相互作用，制作4倍体胚胎，杂种细胞构建和胚胎细胞核移植等方面有重要意义。

During somatic embryogenesis, we were able to trace the FAC1 expression to single embryogenic cells, suggesting its critical role in early induction.

FACl在体细胞胚胎发育过程中的表达可以追踪到单个的胚性细胞，说明它在激活早期胚胎发育中的关键地位。

Placenta as a key temporary organ for maintaining oxygen and nutritive substance exchange in universe and foetus contained immature embryon and adult stem cells that trended to maturity no matter from anatomic structure or growth, besides, placenta could not be related to ethics.

胎盘作为胚胎发育中维系母体和胎儿氧气及营养物质交换的重要暂时性器官，无论从解剖结构还是在发育行为上，都包含了较为幼稚的胚胎及趋于成熟的成体干细胞成分，而且胎盘不会涉及伦理道德问题，目前已成为寻找人类间充质干细胞新来源及提高临床应用效果的研究热点。

The embryological studies of strawberry showed that the ovule of strawberry were hemitropous, the ovule had the obvious hypostace structure, the type of its embryo sac was Polygonum, the embryo sac was long and narrow, the type of development of embryo was the Geum type of the Asterad type, the endosperm was Nuclear type and the somatic embryo sacs happened The integral transparency technique combined with the technique of microdissection was used in this experiment The combination was an innovation in the techniques of section.

对草莓胚胎学的研究结果表明：草莓胚珠横生、胚珠具明显的承珠盘结构、胚囊发育为蓼型、胚囊狭长、胚胎发育为紫菀型水杨梅类型、胚乳核型、并有体细胞胚囊的产生。试验中采用了多种制片方法，其中将整体透明技术和显微解剖技术相结合的方法是在制片技术上的一次创新。

Ovine immatured oocytes, matured oocytes and embryos from 2-cell stage to blastocyst produced in vitro were recovered, and RT-PCR was used to semi-quantify mRNA expression. Proteins of Cx43 and Cx45 were detected by using a combination of immunocytochemistry and Laser Scanning Confocal Microscope.

收集绵羊未成熟和成熟卵母细胞以及体外受精早期胚胎各发育阶段的卵裂球细胞，通过RT-PCR半定量检测Cx43和Cx45基因的mRNA表达量；通过免疫组织化学方法结合激光扫描共聚焦显微镜检测Cx43和Cx45蛋白在绵羊体外受精的早期胚胎发育过程中的表达情况及表达区域。

Results: the findings on ct and mri were as follows: 57 cases of oligodendroglioma, 15 cases of ganglioglioma , 5 cases of dysembryoplastic neuroepithelial tumor , 3 cases of pleomorphic xanthoastrocytoma .conclusion:the images on ct and mri of cerebra peripheral tumor occur some characters , so ct and mri were certain worth on the diagnose and differentiate diagnose of cerebra peripheral tumor.

结果：少枝胶质瘤47例，间变性少枝胶质瘤10例，节细胞胶质瘤15例，胚胎发育不良性神经上皮瘤5例，多形黄色细胞瘤3例。结论：脑浅表肿瘤存在影像特征，ct及mri对其诊断有一定的价值。少枝胶质细胞瘤；节细胞肿瘤；胚胎发育不良性神经上皮瘤；多形性黄色星形细胞瘤；ct；mri

Results indicate that the best time to add FBS is in the fourth day, but in the second day, the development of parthenogenetic embryos is blocked.

结果表明，添加FBS的时间以4d开始效果较好，在胚胎发育的0d、2d开始添加不利于孤雌胚胎的发育。

Here were expression of TGFαand EGFR mRNA in unmatured oocyte, matured oocyte, embryo and the expression of TGFαand EGFR in matured oocytes were comparatively more abundant than that in unmatured oocytes.

GFαmRNA的量在8细胞期下降到最低水平，并随着胚胎基因组的激活胚胎开始转录TGFα，使TGFαmRNA表达总量保持在一定水平，持续到桑椹胚期；EGFR mRNA的量在胚胎发育到桑椹胚期下降到最低，而囊胚期胚胎中的整体表达量又上升。

Mouse zygotic genome is activated at the two-cell stage which implies that embryonic development is transferred from the oocyte itself to the embryo.

在小鼠胚胎发育研究中发现，小鼠的基因组激活发生在2细胞期，这一时期标志着合子的发育由卵母细胞控制向胚胎控制的过渡，期间发生一系列复杂的生化过程。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
