中胚层

Before 30 years old, the mean somatotype of male mainly belonged to balanced mesomorphy category, afterwards that of male turned i...

女性随年龄增长内中因子值增加，外因子值下降，体型愈来愈偏内胚层体型。

LITERATURE EVALUATION: The 32 literatures are about ESCs transcription regulation, the role of FoxD3 for embryonic development and maintaining the pluripotency of ESCs and the function of FoxD3 in other cells （myeloid cells, nervous crest cells and chromatophore cells）.

FoxD3是叉头框（Forkheadbox，Fox）家族中的一个转录调控因子，它对胚胎上胚层及其衍生物的形成和建立多潜能胚胎干细胞系具有重要作用，并与控制胚胎发育和胚胎干细胞多能性的其他转录调控因子有一定的联系。

Morphorgenesis and differentiation of these organs involves sequential and complex interaction between ectoderm, mesoderm and endoderm.

这些器官的成型与分化，皆是由胚胎外、中、内三个胚层组织一连串的讯息传递以及彼此之间的交互作用所完成的。

The study is done to confirm the effective time window of Wnt3a and Activin A in endoderm induction.

研究Wnt3a和Activin A在限定性内胚层诱导中共同作用的最佳时间窗。

These epithelial elements arise embryologically from foregut endoderm in the process of bronchial tubular growth.

这些表皮细胞在胚胎学上把源于支气管生长过程中的前内脏叫内胚层。

To determine whether the same molecular mechanisms are inoled in the formation process, the expression pattern of transcription factors regulating endoderm and gut deelopment in the mouse embryo was examined by in situ hybridization and compared with in io expression.

为了证明在成形过程中是否也具有相似的分子机制，我们通过原位杂交同体内表达比对的方法来检查小鼠胚胎中调节内胚层和肠道发育的转录因子的表达模式。

Transcripts of zebrafish Hspa5 are present in fertilized eggs, suggesting their maternal origin. Zygotic expression of Hspa5 starts during midgastrulation and occurs in the hypoblast cells. It is specifically expressed in the hatching gland and the notochord during segmentation.

结果表明，Hspa5 mRNA在卵子中就存在，是一个母源基因；其合子基因的表达开始于原肠中期的下胚层，在体节期发生在脊索和孵化腺中。

During segmentation,GFP was detected in the notochord but not in the foor plate.

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；在体节形成期，GFP在脊索细胞中表达，但未发现在神经底板细胞中表达。

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。

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。

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
