During the development of dental germ, enamel matrix proteins secreted by epithelial root sheath could induce dental follicle cells to differentiate towards cementoblast and form acellular cementum finally on the surface of tooth root. Many researches of domestic and oversea scholars suggest that enamel matrix proteins could effectively induce periodontal regeneration, and the structure and function of this regenerated tissue are similar to healthy periodontal tissue. Moreover, the regeneration process is nearly the same to that of embryonic development of periodontal tissue.

自发现釉基质蛋白可诱使牙囊细胞向成牙骨质细胞方向分化并在根表面形成无细胞性牙骨质以来，国内外学者做了大量研究，结果表明釉基质蛋白能有效诱导牙周组织的再生，且这种再生组织的结构和功能更接近于健康的牙周组织，并且再生过程也与牙周组织的胚胎发育过程类似。

Many vegetal cells accumulate a great deal of betaine under stress conditions, especially Chenopodiaceae and Gramineae, improving cell osmoregulation ability and stabilizing structure and function of intra-cellular macromolecule protein and biomembrane.

在盐分胁迫下，许多植物特别是黎科和禾本科植物细胞中大量积累甜菜碱，可提高细胞渗透调节能力，稳定细胞内大分子蛋白质和生物膜的结构与功能。

A hydroponical experiment was carried out to study the toxicity of copper, cadmium and their combined pollution on ultrastructure of Commelina bengalensis Linn. Transmission Electron Microscope was used to investigate the effect of heavy metal on ultrastructure of different parts of plants.

为了解铜、镉对泡泡草根、茎、叶细胞亚显微结构的毒害及作用位点，以期为进一步研究鸭跖草属植物的耐重金属机理提供理论基础，本文通过透射电子显微技术研究了75 μmol·L-1铜和50μml·L-1镉及其交互污染对泡泡草根、茎、叶细胞超微结构的影响和铜、镉在细胞中的分布。

To understand the intracellular andintercellular transportation mechanism of BBWV 2,the cytopathological structure of BBWV 2was observed,the subcellular localization of movement protein VP37 and its binding abilityto coat protein were studied.

为了弄清BBWV 2在寄主植物体内的细胞转运机制，本论文对BBWV 2的细胞病理结构进行了观察，对与病毒运动相关的VP37蛋白进行了亚细胞定位，并对VP37的蛋白结合特性进行了研究。

Mouse embryonic stem cells can give rise to ectodermal derivatives in culture and can be further induced into neurons and glia for cell-replacement therapies in the central nervous system and for use in drug discovery.

小鼠胚胎干细胞（embryonic stem cell ， ES cell）体外作育可以剖析成为外胚层结构，并进一步剖析为神经元和神经胶质细胞。这些细胞已用于中枢神经体系疾病的细胞替换治疗和治疗药物的研发。

In the second group of which pancreas allogenic graft was made combining with duodenum: schistic necrosis of pancreatic gland alveolus at 3 d post operation, necrosis of pancreatic folia and pancreatic islet at 5 d post operation, widespread necrosis and disappear of structure at 7 d post operation were observed.

胰、十二指肠移植组：术后3 d胰腺腺泡细胞片状坏死；术后5 d胰腺小叶和部分胰岛细胞坏死；术后7 d腺泡细胞大片坏死，胰岛结构消失。

But soon some of the cells in the gastrula become specialized, a division of labor has set in among the cells which soon deprives them of the capacity to change their own structure and function back to the original state.

但一些细胞在原肠胚很快成为专门的，工作的分配已经设置在细胞之中，细胞很快剥夺他们自己的能力改变他们自己的结构和作用回到原始的状态。

The cells at the edge of the basaloid islands tended to show palisading arrangement. Squamous epithelium on the surface of tumor often accompanied with carcinoma in situ or superficial invasive squamous cell carcinoma. Occasionally cancer nets were connected with basement layer of squamous epithelium laying in the surface, and rare squamous cells or glandlike structures were seen in the cancer nests.

但BSC癌细胞分化较低异型性较强，癌巢周围细胞呈栅栏状排列，肿瘤表面鳞状上皮常伴发原位癌或浅表浸润性鳞状细胞癌；偶见癌巢与表面鳞状上皮基底层相连、或偶见癌巢内形成鳞状细胞，或腺管样结构，这些与ACC不同。

Methods Spermatocytes, early stage spermatids and the later stage spermatids were separated from the adult rat testis by the velocity gravitative sedimentation technique. Using the whole mount electron microscopy, SDS-PAGE and Southwestern blot, the morphology, components of NM-L-IF and the relationship between an A-T repetitive DNA fragment and the proteins of NM-L-IF in those cells were analyzed.

利用整装电镜技术、SDS-PAGE和Southwestern blot等技术观察与分析经单位重力沉降法分离的大鼠精母细胞、早期精子细胞和晚期精子细胞的NM-L-IF的形态结构、蛋白组成及其与A-T重复序列的相互关系。

Histological observation showed no vital osteocytes were found in bone lacuna and vessels perforating into Haversian canals disappeared in control group after operation.

细胞和矿化的细胞间质组成的骨组织有其独特的生物组织学特性，为人体最坚硬的结缔组织，即使其细胞成分全部坏死，仍可在一定的时期内保持其组织学结构形态，且仍具有一定的生物力学功能。
