一。目的和意义许多细胞表面糖蛋白或糖脂是含有岩藻糖(Fucose， Fuc)化的糖链，参与胚胎发育、组织器官形成，并且与肿瘤的生长、浸润有关，如LeY、LeX、sLeX等Lewis系血型抗原分子。

The ability of multiple lineage differentiation and long term self-renewal make stem cells to be the most important "seed cells" in future regenerative medicine and the best tool for the research in human early germ layer specification and organogenesis, drug screen and gene therapy.

干细胞具有的多向分化潜能和自我更新能力使其成为未来再生医学的重要种子细胞，并成为研究人类早期胚层特化和器官形成、药物筛选以及基因治疗的最佳工具。

It is about 2.4cm long, with most of the internal organs formed.

这是有关二点四厘米长，大部分的内部器官形成。

The development and formation of above ground organs in wheat plant were simulated systematically and comprehensively, including leaf blade, internode and tiller.

对小麦植株地上部器官形成过程进行了较为系统、全面的模拟研究，建立了包括叶片、节间和分蘖的解释性动态模型。

From botanical point of view, photosynthesis and organogenesis are main functions for plant growth.

从植物学的观点来看，光合作用和器官形成是植物生长过程中的两个主要部分。

And have a central role in vertebrate and non-vertebrate organogenesis.

并且在脊椎动物和非脊椎动物的器官形成过程中起重要作用。

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。

The ameloblasts are the key cells during odontogenesis, and they have been already cultured in vitro. The amelogenin is the extracellular matrix synthesized and secreted by the ameloblasts, and it plays a crucial role during amelogenesis.

成釉细胞是牙器官形成的关键细胞，国内外已成功离体培养出成釉细胞，成釉细胞合成和分泌的细胞外基质－釉原蛋白在釉质的形成中起着关键作用。

Stress reduces neurogenesis in the dentate gyrus subgranular zone, but it is unknown if stress-induced changes in neurogenesis contribute to individual vulnerability. Using a chronic social defeat stress model, we explored whether the susceptibility to stress-induced social avoidance was related to changes in SGZ proliferation and neurogenesis.

长期压力已知会引起一些精神疾病，可是尚不清楚一些人比另外一些人更容易产生这些症状的神经器官基矗Bmelia Eisch及其同事研究了大脑的海马区——对进修和记忆具有重要性的区域——并探索了神经器官形成对受压力影响严重的大脑功能的作用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
