胚胎发育

Our study showed that the exposure to PCBs/PCDFs in utero by the female Yucheng adolescents did not have remarkable effects on their pubescent and postpubescent development of reproductive and endocrine functions.

我们的研究显示油症少女虽在胚胎期暴露到多氯联苯/多氯夫喃，但此暴露对她们在青春、后青春期的性徵发育及内分泌功能的影响并不显著。

These defined stages are embryonic, prepubertal, pubertal, pregnancy, lactation and involution.

它的发育阶段分为胚胎期、青春前期、青春期、怀孕期、泌乳期和退乳期。

The fertilized egg at the pronuclear stage (prior to the first cell division) is then placed into the fallopian tube hoping that the tubal environment, just as in GIFT, will aid in embryo development, growth and pregnancy.

将原核期的受精卵移植回输卵管环境，此时就同GIFT一样了，这将有助于胚胎的发育。生长和妊娠。

After being transplanted into uterus of synchronously pseudopregnant mouse on pregnant D4, the embryo at blastocyst stage successfully implanted and normally developed onto term in the recipient uterus.

这些胚胎被移植到同步假孕小鼠子宫内后可以着床并发育到分娩。

Retinoic acid and its receptors play a very important role in the development of the embryo.RA signal transduction is mainly mediated through it\'s two kinds of receptors, retinoic acid receptor and retinoid X receptor, each kind of receptor has 3 isoforms, a, 6,?.

维甲酸(Retinonic acids，RAs)和其受体在胚胎的发育过程中起着很重要的作用，RA信号的传导主要通过它的两种受体即维甲酸受体和维甲酸类X受体，每种受体又有3种亚型，α，β，γ。

POU1F1 gene belongs to the family of POU gene. It plays a critical role in the embryonic differentiation and growth of the somatotropic, lactotropic, and thyrotropic cell lineages.

POU1F1基因是POU基因家族的成员之一，在胚胎分化和生长激素、催乳素、促甲状腺素细胞系的发育中发挥着重要作用。

Its expression is both temporally and spacially regulated during fetal and postnatal development.

在胚胎期和出生后期的发育中其表达受时间和空间调控。

Embryonic stem cell has the totipotency, but the induction mechanisms are not identified at present.

胚胎干细胞具有发育全能性，目前其定向诱导机制尚不明确。

Plant somatic embryogenesis is a good experimental system for cell differentiation, development, totipotency expression and crop cultivar improvement, which have very important theoretical and practical significance.

植物体细胞胚胎发生是现代生物技术研究中的一个重要领域，它为研究植物细胞的分化、发育、全能性表达和作物品种改良等提供了良好的体系，在理论上和应用中都具有重大意义。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
