中胚层

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。

Many signaling pathways play important roles in the formation of mesoderm and patterning of the neuroectoderm during early development of vertebrate embryos.

在脊椎动物胚胎的早期发育中，多种信号途径对中胚层形成和神经外胚层分化起着重要的调节作用。

Hoxd13 gene is expressed in cloacal mesoderm, and its expression domains in the hindgut demarcate morphologic boundaries.

Hoxd13基因表达于泄殖腔的中胚层，Hoxd13基因在后肠中的表达可作为划分后肠形态学界限的依据。

Recent studies have begun to elucidate how the endothelial lineage is specified from the nascent mesoderm. However, the molecular mechanisms which regulate this process remain largely unknown.

近年的研究揭示了内皮细胞系是如何从新生中胚层中特化而来的，但是调控这一过程的分子机制仍很不清晰。

FOXC2 protein and mRNA were extensively expressed in pregnant 40 day embryonic somite and neural tube mesoderm which would form cardiovascular and axial skeleton primordia, especially strong expressed in the cells of mesenchyme surrounding notochord and dorsal aorta approaching the head.

这个基因广泛表达在孕40天胚胎体节和神经管周围未来分化为心血管和中轴骨骼始基的中胚层，靠近头部围绕脊索和背主动脉的间充质细胞核中表达强烈。

Because of the significance of zebrafish Dapper2 in mesoderm induction, the mouse dapper2 was cloned following its homolog. The study of its spatial and temporal expression pattern showed that it expressed specifically in otic vesicle, somite,gut and roof plate of mouse embryos.

鉴于Dapper2对于胚胎中胚层发育的重要性，本文首先克隆出小鼠Dapper2基因，并研究其时空表达谱，发现它在体节形成期后在体节、耳泡、神经顶板、肠等组织中特异性表达。

Basic fibroblast growth factor is a potent mitogen for a variety of mesoderm- and neuroectoderm-derived cells and has been found in aqueous humor, vitreous and other ocular tissues.

碱性成纤维细胞生长因子（basic fibroblast growth factor bFGF）是对广泛来源于中胚层和神经外胚层细胞的有效促细胞分裂因子，已在房水、玻璃体和其它眼组织中发现。

According to 5'flank regions and partial sequences of the MyoG gene in Sus scrofa, Bos taurus, Homo sapiens, and Mus musculus published in GenBank, the homogeneous primers were designed to amplify the promoter region of Gansu wapiti MyoG by Touch-Down PCR.

MyoD和MyoG是一类肌调节蛋白，其中MyoD代表肌源性的发生；MyoG诱导骨骼肌的最终分化，调控中胚层细胞分化为成肌细胞，再由成肌细胞融合为肌纤维这一过程，在肌细胞分化过程中起着中心调节作用，是唯一的不可替代的成肌调节因子[2]。

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。

Background:Multipotent mesenchymal stem cells are multipotent stem cells that can differentiate into tissues of mesodermal origin and can be isolated from various tissues.

背景：间充质干细胞(multipotent mesenchymal stem cells，MSC)是能分化为中胚层组织的多能干细胞，它可以从机体的各种组织中分离得到。

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
