Furthormore, xNorrin can not activate canonical Wnt signaling in the endomesoderm, suggesting additional mechanisms to restrict xNorrin activity in the ectoderm besides of its RNA localization in the animal pole..

进一步的体内实验表明，xNorrin协同xFrizzled4及xLrp5/6只能在外胚层激活经典Wnt信号通路，而在内中胚层中这种活性则很低，提示除了其RNA定位在动物极细胞之外，还存在着另外一种分子机制将xNorrin的活性限制在背部外胚层。

The syndrome seems to result from disturbances of the caudal mesoderm before the fourth week of gestation. This includes the caudal cell mass and the cloaca, what explains the associated anomalies of the genitourinary tract (24%) and lower gastrointestinal tract.

本病是妊娠第4周之前尾部中胚层的紊乱所致，包括马尾细胞团和泄殖孔，这解释有24％的病例伴有泌尿生殖道畸形和下胃肠道畸形。

BACKGROUND: The basic fibroblast growth factor has the obvious promotion function of multiplication of the mesoderm and nerve ectoderm cells, and has the indirect ossification to the bone marrow-derived mesenchymal stem cells.

背景：碱性成纤维细胞生长因子对来源于中胚层和神经外胚层的细胞具有明显的促进增殖作用，对骨髓间充质干细胞具有间接的成骨作用。

Its major components are different kinds of cells and extracellular fibres and ground substance, which varies in consistency from thin gel to rigid structure.

结缔组织的胚胎起源是中胚层，主要由细胞、三种蛋白质纤维及大量不定形碳水化合物基质构成。

It was needed only 20-30 minutes; the active components can be transformed into high concentration active substances, nonstop to the deep skin, the active components infiltrate to Subcutaneous tissue through the channels among Hair follicles, sweat glands and cells, reach the mesoblast .then it open the entrance easily by stimulating the water channels protein on the cell membrane, infiltrate the cell membrane, make the skin cells to absorb nutrients plenary.

需20-30分钟即可将活性成分快速转换成高浓度的活性物质，直达深层皮肤；利用"水电泳"技术，活性成分通过毛囊、汗腺与细胞间通道渗透皮下组织，达到中胚层通过刺激细胞膜上的"水通道蛋白"，轻易打开入口，渗透细胞膜，使皮肤细胞充分吸收营养成分

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。

Then, under the control of systemic factors, mesenchymal cells aggregate and differentiate to form catilage blastemal elements that prefigure skeletal limb components.

脊椎动物胚胎期骨与关节系统的发生是一种复杂生命现象，起始于中胚层间充质细胞的定向聚集，形成肢芽，然后在一系列作用因子的调控下，肢芽内细胞进一步分化，形成具有骨骼雏形的软骨原基，后者经软骨内骨化发育成骨。

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

No US-pin plastic treatment therapy, a comprehensive alternative to traditional plastic injection of the United States (with the needle and micro-needle) is efficient, non-invasive and safe,"mesoderm into beauty therapy" is the latest technology of water use and water channel protein electrophoresis principle of development Note the infiltration hole electric technology to non-needle injection principle, the use of "point to a plane," AMD permeation technology in skin electroporation Act under the influence of pulsed current stimulation, so that pores have a physical reaction to the rapid spread in two seconds 650-800 of fine pores, forming an instant electronic delivery channels of nutrition, nutrition Note dialysis therapy immediately with electrophoresis, soft laser stimulation and ice, etc., in the most secure and fast, the skin will be required for nutritional products , 99% transmitted to the basal cells, and can be stored as long as 72 hours, the skin smooth and more compact, creating a perfect Beautiful Skin.

无针美塑治疗疗法，是全面替代传统注射美塑的高效、无创，安全的&中胚层导入美容疗法&，是运用最新技术水电泳和水通道蛋白原理研制出的电孔注渗技术，以无针注射原理，采用&点到面&超微渗透技术，其电穿孔法令肌肤在脉冲电流刺激影响下，使毛孔产生物理反应，在两秒内迅速张开650-800个微细毛孔，瞬间形成电子营养输送通道，营养注渗疗法随即展开，配合电泳、柔激光和冰封等刺激作用，在最安全和快速的情况下，将皮肤所需的营养产品， 99%输送到基底层细胞，并可储存72小时之久，令肌肤更紧致柔滑，缔造无瑕美肌。

Fibroblast growth factor is a kind of the polypeptide growth factors, which is known to be a mitogen for a wide variety of mesoderm-and neuroectoderm-derived cells and a neurotrophic factor for several neuronal cell types.

成纤维细胞生长因子是一种对中胚层及神经外胚层源的细胞都有促分裂活性的多肽生长因子，也是一种重要的神经营养因子。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
