There are commonly eight nuclei in the embryo sac: the egg apparatus at the micropylar end, made up of an gee nucleus and two synergid nuclei; three antipodal cells at the oppsite chalazal end that probably aid embryo nourishment; and two polar nuclei in the center that fuse to form the primary endosperm nucleus.

通常胚囊中有8个核，卵器在珠孔端，由卵和两个助细胞组成；3个反足细胞在合点端，可能为胚胎提供营养；胚囊中央有2个极核，融合在一起形成最初的胚乳核。

The part of the embryonic mesoderm, consisting of loosely packed, unspecialized cells set in a gelatinous ground substance, from which connective tissue, bone, cartilage, and the circulatory and lymphatic systems develop.

In contract, the tumor tissue of control group kept morphology, tumor nodules composed of undifferentiated carcinoma, and some karyokinesis could be seen, some spotty necrosis were found occasionally in where the structure among tumor cells were loose associated very slight inflammatory response; At the 21 days after injected AdCMVIL-12, the tumor boundary of AdCMVIL-12-Ⅰ group were clear and felt hard by touch, section showed grey.

同期的对照组绝大多数肿瘤细胞形态完好，排列紧密，由大量未分化的肿瘤细胞组成并可见多个核分裂像，偶尔可见散在的点状坏死灶，瘤细胞之间结构松散，炎症反应很轻；AdCMVIL-12注射后第21天时，AdCMVIL-12-Ⅰ组的肿瘤组织经手摸感觉瘤体境界清楚、发硬，切面呈灰白色。

间叶细胞胚胎的中胚层部分，由生长于胶状基质的、结构松散的、无特定功能的细胞组成，这些细胞将会发育成结缔组织、骨、软骨、血液及淋巴系统

The sensitization system of an ommatidium included 11 retinular cells, of which four located at the distal part of the ommatidium; seven formed the proximal main part of the retina. The two parts are some one on top of another.

透射电镜观察显示红螯螯虾小眼的感光系统由11个小网膜细胞组成，其中4个小网膜细胞位于晶锥之下，构成了感光部分的远端，7个小网膜细胞构成感光系统的近端主体，上下两部分有重叠。

Simple cuboidal epithelium is a single layer of cells whose width and height are approximately equal.

单层立方上皮由单层细胞组成，细胞的宽度和高度近似相等。

BACKGROUND: One of the key neuropathological changes in Alzheimer disease is that neurofibrils over phosphorylated cytoskeletal protein composed of entwist together, and the phosphorylation of τ protein can be catalyzed by cyclin dependent kinase 5 (CDK5),however whether the phosphorylation of neurofilaments can be catalyzed by CDK5, as well as its role in the pathogenesis of Alzheimer diseases is less acknowledged.

背景：阿尔茨海默病的主要神经病理学特征之一是由过度磷酸化的细胞骨架蛋白如(o，神经细丝组成的神经原纤维缠结，细胞周期蛋白依赖性蛋白激酶5可催化蛋白的磷酸化，但神经细丝是否可被细胞周期蛋白依赖性蛋白激酶5磷酸化及其在阿尔茨海默病发病中的作用却知之甚少。

Neurovascular unit was an integral one that consisted of neuron,vascular endothelial cells,et al.

神经血管单元是指由神经细胞、血管内皮细胞、星形胶质细胞及其周围的细胞外基质组成的一个整体。

The tripartite cytolethal distending toxin induces cell cycle arrest and apoptosis in eukaryotic cells.

由三部分组成的细胞致死性扩张毒素诱发真核细胞周期停止和凋亡。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
