胚层

From E12. 5 onwards, partially distinct patterns of expression of these genes are observed in the neuroepithelium, sense organs and endodermal-derived organs.

从E12.5起，这些基因显示出部分表达差异，尤其在神经上皮，感觉器官和内胚层衍生的器官中。

BACKGROUND: At present, studies show that a kind of stem cell community which in many kinds of organizations can differentiate into tissue cells of different embryonic layers; but those are different from embryonic stem cells, embryonic stem cell will lose the part differentiation potential gradually during the development of pregnancy, and will present some special phenotypes or the molecular markers, as CD105 and so on, will call it postembryonic pluripotent stem cells.

背景：目前研究认为在胚胎发育后的多种组织中存在一类干细胞群体，可分化为不同胚层的组织细胞；但又不同于胚胎干细胞，随着妊娠期间胚胎的发育胚胎干细胞会逐渐失去部分分化潜能，会出现一些特殊表型或分子标记，如CD105，称其为胚胎后亚全能干细胞。

Pure silicalite only exposed at surface is silica-bearing rocks of protore beds experiencing extreme oxidation at surface as additional production while generating oxidized manganese ores

纯硅质岩仅见于地表，是含硅质的矿胚层岩石，在地表经强烈氧化作用形成氧化锰矿石同时产生的&副产品&。

O?C?Cu isotopes. revealing that the mixed hydrothermal fluid of magmatic water and meteoric water reactivated the ore elements in the carbonate rocks and quartz diorite. Copper was transported, as Clcomplexes in the ore fluid and precipitated to enrich and thicken the primary sedimentary protore.

认为该矿床是在岩浆水和后期少量大气水的加入而形成的混合热液共同作用下，活化碳酸盐岩地层和石英闪长岩中的铜等成矿元素，形成含矿热液，并以铜的氯络合物方式运移，在弱还原性条件下使原始沉积矿胚层加厚变富。

Chordates are bilaterally symmetrical, triploblastic, segmented coelomates which demonstrate a deuterostomic pattern of early embryonic development.

脊索动物两侧对称、三胚层，分节的体腔，在胚胎发育的早期过程中，显示为后口类型。

Although Pygo expressed ubiquitously in the embryo, it expressed at relatively high level in pre-blastoderm embryos which indicated a high degree of maternally provided message, followed by a low level of ubiquitous zygotic expression.

结果表明，虽然pygo普遍表达于整个胚胎中，并且在果蝇胚胎发生全过程都有，但Pygo在前囊胚层(pre-blastoderm)中的表达水平相对较高，这说明胚胎发生过程中来自母方的贡献较高。

For example, identifying genes expressed during culture, as well as their temporal expression order after passaging and conditions influencing the formation of all three germ layers may be helpful for the production of functional beta islet cells used in treating type I diabetes.

比如说，在经过以及影响三胚层形成的条件之后，识别出在培养条件下表达出的基因以及他们暂时的表达顺序可能有助于生产有功能的胰岛B细胞，而这种细胞是用来治疗I 型糖尿病的。

Its absence perturbs the balance between actiation of the JAK–STAT and SHP-2–ERK-1/2–MAPK pathways, resulting in less self-renewal and a greater potential for differentiation into the primitie endoderm lineage.

SOCS-3的缺乏破坏了激活JAK–STAT和SHP-2–ERK-1/2–MAPK信号转导通路之间的平衡，这就导致了较少的自我更新，而是较强的分化成原始内胚层谱系的潜能。

Its absence perturbs the balance between actiation of the JAK-STAT and SHP-2-ERK-1/2-MAPK pathways, resulting in less self-renewal and a greater potential for differentiation into the primitie endoderm lineage.

它的缺乏干扰了JAK-STAT和SHP-2-ERK-1/2-MAPK 通路之间的平衡，最终导致自我更新能力减弱和更易于向原始内胚层分化。

There were all kinds of tissue cells in the teratomas acquired from in-vitro differentiation, such as, neuro epithelium, skeletal muscle, respiratory epithelium. This further proved the isolated mouse ES cells could differentiate into three germ layers of tissue types.

体内分化实验所获得的畸胎瘤中存在各种组织细胞，如一些神经上皮样组织；横纹肌；呼吸上皮样组织等，这进一步证明所分离获得的小鼠ES细胞具有三个胚层的分化能力。
