查询词典 embryonic development

Because of this situation, we suggested that the construction of human embryonic stem cell research regulations in Taiwan should be of first priority and illegal use of human embryo or unpatentable types of human embryonic stem cell inventions should be regulated by law. Moreover, following the trend of stem cell technology, the regulation of cell therapy, gene therapy and analysis or diagnostic technologies related to stem cells should be amended to support stem cell research and research foundation, research awards or preference of business investment should be established to improve development of stem cell industry in Taiwan.

据此，本研究建议我国应优先建制人类胚胎干细胞研究管制规范，并以法律明订违法使用人类胚胎之情况或不予专利之人类胚胎干细胞发明态样，另一方面配合干细胞技术的应用趋势，对於干细胞相关的细胞疗法、基因疗法以及干细胞特性检测等潜在发展领域进行相关规范之增修，并且针对干细胞产业设立研究基金、拟定奖励研究或优惠投资方案，以达到促进干细胞产业发展之政策目的。

被诱导的心肌细胞的判定除常规指标外，我们还用了心脏特异性引物β-MHC对不同收缩时间的心肌细胞总RNA进行RT-PCR扩增和RNA斑点杂交，发现该心肌细胞不仅具有正常心肌细胞的特性，而且在分化早期就高度地表达心脏特异性基因。

As soon as embryonic tissues are sufficiently differentiated movement and primitive stages of behavior appear, and these develop pari passu with further embryonic development.

只要胚胎的组织一经过充分的分化，行为的动作和行为的原始阶段就会出现，而且这些发展和进一步的胚胎发展同种速度。

Observations on embryonic stage and nuclear number The embryonic development stage of encysted embryos of four Artemia populations from Qinghai-Tibet Plateau was studied with paraffin section method, and the nuclei numbers of encysted embryos were estimated by counting nuclear on squashed preparations.

不同种群卤虫卵卵壳结构的观察比较利用扫描电镜和透射电镜对七个种群(GH、AQK、山西解池SIN、山东埕口盐场CK、西藏、新疆鲸鱼湖、西藏拉果错湖LGC)的卤虫卵的卵壳结构进行观察。

In mammals, the Notch signaling pathway is critical for embryonic development, as targeted disruption of Notch1 or its downstream transcription factor RBP-J in mice resulted in disorganization of somites and delayed closure of neurotube, which finally leads to early embryonic lethality.

Notch信号途径在哺乳动物的胚胎发育中起着关键的作用。

On the investigation, main factors impacting success of A company product development management is product development progress, product development flow management, process monitor, organization structure, product development quality , product development cost, management mechanism of product development project, resource match, and establishes ISM of factors, the degree of base factors impacting the success of product development management decreasingly is product development management flow, management mechanism of product development project, organization structure of product development management with AHP method.

其次，借鉴业界经验并通过高层领导小组研究讨论，确定了A公司产品开发管理效率的评价指标，对评价指标采用逐对比较法判断指标的相对重要性；通过调查得出影响A公司产品开发管理效率的八个主要因素，它们分别是产品开发进度、产品开发流程、过程监控力度、组织结构、产品开发的质量、产品开发的成本、产品开发项目的管理机制和资源匹配的齐全度。建立了影响因素的解释结构模型，运用层次分析法得出影响产品开发管理效率的根本因素，并按影响程度，由大到小排序为产品开发管理的流程、产品开发项目的管理机制、产品开发管理的组织结构。

Early embryonic cell has the developmental totipotency. Every embryonic blastomere cell can develop to an intact individual separately in a proper condition.
