The modulations of beta-catenin and caspase-3 levels were investigated in the KM mouse embryo following maternal treatment with a single oral dose of 30mg/kg body weight of RA during the neurula period.

流行病学研究显示，在胚胎发育过程中摄入过多维甲酸可致各种发育缺陷，其中神经管畸形最为常见。

A minute structure in seed plants, containing the embryo sac and surrounded by the nucellus, that develops into a seed after fertilization.

Lthough a low frequency of abnormal growthof nucellus was observed,no embryo originating from nucellus cell and integumentwas found.

PⅣ珠心组织出现低频率的异常生长现象，但未观察到由珠心细胞发育形成的不定胚。

It includes the process whereby a diploid cell of the nucellus develops into an embryo giving a diploid seed with a genetic constitution identical to the parent.

在另一种无融合生殖中，种子从未受精的配子中发育而来，这被称为孤雌生殖。

The changes of nucleic acid,protein and starch content in ovules had a significant effect on embryo development.

龙眼胚胎的发育状况与胚珠内核酸、蛋白质和淀粉含量的变化密切相关。

The International Stem Cell Corporation, in Oceanside, California, for one, reckons it can do so and, at the same time, deal with the ethical issue of embryo destruction.

比如，坐落于加州欧申赛德的国际干细胞公司就是其中一个，该公司认为他们不仅能完成Geron所做的，并能同时处理好杀死胚胎方面的道德问题。

The efficiency of the nuclear transfer was 63.6%(63/99).Forty-seven clone embryos were transferred into 5 recipient goats. After embryo transfer, two recipient goats have not been seen oestrous within 2 oestrum, and one of the two recipient goats was examined positive by gravid testing, which testified the clone embryos were viable in the uterus of recipient goats.

阳性细胞克隆中的2株(M9，M10)已经进行了首次细胞核移植，核移植成功率为63.6％(63／99)，将47个发育较好的克隆胚胎进行了胚胎移植，共用受体羊5只，2只受体羊2个情期未见返情，在没有返情的2只受体山羊中有1只妊娠检测阳性，说明转基因克隆胚胚胎移植后在受体山羊体内发育良好。

Furthermore, ed embryo exhibit extra C.N.S. and P.N.S. neurons. Ed also serves in Drosophila eye development and mesothoracic bristle development. Photoreceptor cells of the ommatidium and bristles are sensory nerves. We suggest that Ed might meditate the development of the nervous tissues.

此外，ed mutant胚胎有过多的中枢以及周边神经细胞生成，Ed亦参予在果蝇复眼发育以及背板刚毛的形成过程，果蝇复眼感光细胞以及刚毛均为周边神经细胞，显示Ed对於神经细胞生成具有某种程度的影响。

Objective To study the role of placenta on fetal hematopoiesis during embryo ontogeny, so as to find a new source of hematopoietic stem/progenitor cells for clinical transplantation.
