The 44 days of pregnancy, B-shows may see yolk sac, the doctor said that embryos may be too small to see, or it may be bad embryos.

Many fetal liver cells were EGFP positive in E13. 5 embryos as well as most of yolk sac was EGFP positive.

To understand the factors effecting on mammalian early embryo development, we carried out the study through 3 points of view, oocytes, zona and embryo culture in vitro.

本研究分别从卵母细胞、透明带以及胚胎体外培养三个角度来探讨影响哺乳动物早期胚胎体外发育的因素。

The amniotic fluid and allantoic fluid of chicken embryo have been analyzed and the resonances of most substances in them were assigned by 1-dimention and 2-dimention Nuclear Magnetic Resonance methods. This work could be the basis of quantitative analysis of metabolites and studying the metabolites changing between the amniotic and allantoic fluid during the hatching process. Also, it provided a new way to study the process of embryo developing.

用一维及二维液体高分辨核磁共振(Nuclear Magnetic Resonance，NMR)方法综合分析了鸡胚羊水和尿囊液的成分，对其中的大多数谱峰进行了归属，发现了一些未经报道的小分子代谢物，为研究胚胎发育过程中各个胚囊中体液的交换和小分子的代谢以及进一步对发育过程中代谢物含量变化的定量研究打下了基础，并为研究胚胎发育的过程提供了新的思路。

Androgenic and antiandrogenic effects and expression of androgen receptor in mouse embryonic stem cells ...

This result indicates that WT1 gene plays an important role in differentiation and development of fetal kidney and may be the factor that promotes metanephric blastemal cell to differentiate into epithelial cell.

结果显示小胎龄肾组织中WT1蛋白在胚基细胞和幼稚肾小球细胞核表达而大胎龄组肾组织中WT1在肾小管细胞胞浆表达，阳性率分别为57.1％(8/14)和46.2%(6/13)，提示WT1基因在胚胎肾分化发育的过程中起着重要作用，WT1蛋白可能是促进后肾胚基细胞向上皮细胞分化的调控因子，其表达在时间上和空间上都受到严格的调控，WT1的表达异常可能导致胚基细胞分化停滞。17例肾母细胞瘤WT1蛋白表达阳性率为41.2%(7/17)，阳性部位在胚基型和上皮型肿瘤细胞核，表达部位和阳性率与早期胚胎肾相似，其中间质型肾母细胞瘤均为阴性，胚基型和上皮型肾母细胞瘤阳性率70%(7/10)，两组间阳性率有显著差异。

Kansas Senator Sam Brownback is a sponsor of a bill that outlaws the cloning of human embryos for research, because he says it's a life form that is eventually destroyed to harvest stem cells, and in his view that makes it abortion.

布朗柏科是这一个立案的提案人，立案为禁止因研究为目的的人类胚胎的复制，原因是他认为人类胚胎已经是生命了，而且那最终就是对于有收获的干细胞的摧毁，按照他的观点，那就是如同堕胎。

Results Expressions of pDGF-BB chain and PDGFR-α mRNA were low at the pseudoglandular stage of day 18, reached the peak level at the canalicular stage of day 19 and the sacculate stage of day 21 of gestations, fell again in newborn rats, and then increased in adult rats.

结果 (1)PDGF-BB、PDGFR-α mRNA随胎龄增长而增高，高峰在19～21天，新生时表达减少，成年时又增高到接近胚胎晚期水平；PDGF-AA和PDGFR-β mRNA在胚胎晚期、新生与成年鼠肺中均有表达，不随胎龄增长而变化，肺内PDGFR-β的表达高于PDGFR-α。
