胚胎

He dissected their embryos and documented every stage of their embryonic life.

他解剖它的胚胎，记下了它的胚胎时期每一阶段的发育情况。

Techniques in embryo technology (such as in vitro production of embryos and animal cloning) need large quantities of high quality oocytes. But the quality of in vitro matured oocytes from slaughtered animals is generally lower than that of the in vivo matured oocytes. It is usually thought that the reason for this poor quality in in vitro matured oocytes is the lack of capacitation during the dominancy of follicular development in vivo.

目前胚胎工程技术研究和开发(如体外生产胚胎和体细胞克隆等)需要大量高质量的成熟卵母细胞，但利用屠宰动物卵巢卵母细胞经过体外成熟培养而获取的卵母细胞质量还远不如体内成熟卵母细胞，其原因一般认为是由于缺乏体内主卵泡阶段的获能作用。

This reports about the study on the femalereproductive organ in the two differren-productivity Ovis aries. Study on the expressing level ofvascular endothelial growth factor receptor—Flt-1 gene of reproductive organ in pregnant sheep.It provided a method for further studying on embryo transplantation, embryonal ectogenesis,treatment of disturbance of genital system of female mammalian.

因此本文以繁殖力高低不同的两个绵羊品种为研究对象，研究血管内皮生长因子受体——Flt-1基因在其妊娠期生殖器官表达变化水平，以期为对哺乳动物胚胎的体外发育、胚胎移植和雌性哺乳动物生殖系统疾病的治疗提供参考依据。

Embryo small to not so long ago that according to this according to the Do not look uncomfortable on the development of early embryos to be not bad not so good of you effemination Ha, ha, ha!

胚胎还小不要这么早就去照这照那的不要不舒服就去看对早期胚胎的发育不好的说句不好听的不要那么娇气的啦哈哈哈！

Hedgehog基因是编码一系列分泌蛋白的基因家族，在果蝇中调控胚胎发育的许多事件，且对胚胎发育过程中的细胞分化和增殖起重要作用。

Study of the embryologic origins and development of the nervous system from fertilization to the 8th gestational week of development.

神经胚胎学是一种胚胎学起源的研究和神经系统从受精到怀孕第八周的发展。

The first pathogenetic gene identified is α-synuclein, but its phathological mechanism is unknown. In previous study, it's demonstrated that all synuclein isoforms expressed massively in early embryologic development of the central nervous system.

先前有研究指出所有的synuclein异构型在胚胎发育早期即在中枢神经系统被大量表现，显示这一类基因对中枢神经系统的发育可能是很重要的，但是研究synuclein在胚胎早期发育方面的相关研究则较少。

But he'd rather burn off my feelers and watch me squirm.

可他却放任那个家伙对我为所欲为！
