胚层的

During male and female reproduction organ developments, CBKs were expressed obviously in temporal and spatial difference manners, especially in pollen development, tapetum cell development and degeneration and ovule development.

这种差异性突出体现在花粉细胞的发育、绒毡层细胞的发育和凋亡以及胚珠的发育等过程中。

The dult stem cells abilities of differentiation, self-renewing and self-maintenance tended to be limited so that it, which is characterized of short life time, could differentiate by means of mono-direction or double direction. What is the most important is that it can not differentiate all cells from the three embryonic layer.

成体干细胞具有一定的生长期，其分化能力、自我更新、自我维持能力具有局限性，生存时间相对较短，仅能单向或双向分化，其重要特点之一是它不能分化成机体所有的三个胚层来源的细胞。

Yet in many vertebrate groups, teeth are not restricted only to the oral cavity, but extend posteriorly as pharyngeal teeth that could be derived either directly from the endodermal epithelium, or from the ectodermal epithelium that reached this location through the mouth or through the pharyngeal slits.

但在很多脊椎动物里牙齿的发育不仅只有上述来源，还有向后延伸形成的咽部牙齿，可能由内胚层上皮或经由口腔或口咽裂至此部位的外胚层上皮形成。

Altogether, this study provides an induction protocol to obtain endodermal insulin-producing cell clusters and hepatocyte-like cells from mES cells.

综合以上所有结果，本实验提供了一个可从小鼠胚胎干细胞获得源自内胚层来的产生胰岛素的细胞和像肝细胞的细胞之诱导分化方法。

We conclude that UCMSCs, with a newly demonstrated endodermic differentiation potential, might be an alternative source for liver-directed cell therapies.

UCMSCs新近被证实具有内胚层分化的潜能，可作为肝细胞基因治疗的一个可供选择的来源。

Bone marrow-derived mesenchymal stem cells are a population of cells capable of replicating as undifferentiated cells and that have the potential to differentiate to lineages of mesoblastic origin. And the characters of BMSCs have suggested the great value of this specific cell population for tissue engineering.

骨髓间充质干细胞具有自我复制、未分化的特点，并可在不同条件下分化为中胚层起源的多种细胞，这些特点决定了其在组织工程中的重要地位。

This process, called vasculogenesis ,involves the de novo differentiation of endothelial cell from mesodermal precursor to form the primitive blood vessel network.

血管生成是指在胚胎发生和器官形成过程中，从中胚层内皮细胞中分化出新的内皮细胞以形成原始血管网的过程，仅见于胚胎发生的早期，出生后即停止。

Their ability to self-renew and differentiate into tissues of mesodermal origin (osteocytes, adipocytes, chondrocytes) and their lack of expression of haemopoietic molecules are currently the main criteria for isolation.

当前分离的主要标准是根据他们自我更新并向中胚层来源组织（骨细胞，脂肪细胞，软骨细胞）分化的能力以及缺乏造血相关分子表达的特点。

Lineage-tracing analyses indicate that the ectopic endothelial cells in embryos with decreased Notch activity originate from mesodermal cells that normally produce erythrocyte progenitors.

命运追踪结果显示，Notch降低的胚胎中，异常增加的内皮细胞是来源于本应该形成红细胞前体的中胚层细胞。

The company is headquartered in Guangzhou, Shenyang, Wuhan, Shanghai and Singapore branches. In 2001, the company joined the Chinese Ministry of Health under the Chinese Medical Association communicate to become executive director of the unit. Early in 2005, the company entered the beauty industry, with the Korea Association of shaping a strategic partnership set up to introduce a sweeping throughout Europe and the United States, Korea and Japan and other countries revolutionary rejuvenation and slimming technology Cosmetology mesodermal U.S. Plastic therapy; 2006, the company spent a lot of efforts to consider the introduction of original import from France hyaluronic acid filler products to enter the medical plastic industries and in Beijing, Shanghai, Shenzhen and other cities in hospital for more than three clinical experiments, the authority to create brand image.

公司总部设在广州，沈阳，武汉，上海，新加坡等地设有分支机构。2001年，公司加入中国卫生部下属的中国医疗交流促进会，成为常务理事单位。2005年初，公司进入美容产业，与韩国整形协会建立了战略伙伴关系，引进了风靡整个欧美国家，韩国及日本等国家革命性的嫩肤及纤体美容科技中胚层美塑疗法；2006年，公司经过多方考虑从法国引进原装进口玻尿酸填充系列产品，进入医学整形行业，并在北京，上海，深圳等城市的多家三甲医院进行临床医学实验，打造权威品牌形象。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
