扁平细胞

After 7 days, some black, circular RPE cells climbed out slowly. Ten days after, cells became irregular, polygon with monolayer-coalesce in bottle bottom, which symbolized as the typical cobble-stone modality after about 13 days.

结果：组织块1d后贴壁，7d后可见有黑色、圆形的RPE细胞缓慢爬出，10d后细胞变成扁平不规则多角形，约13d后细胞基本单层融合长满瓶底，形成典型的鹅卵石样。

In squamous cells, the nucleus was flat o r ellipsoid with far more euchromatin than heterochromatin, and had smooth outli nes without marked invagination of the nuclear envelope.

两种不同活动状态的细胞，扁平形细胞和立方形细胞，在核与胞质的超微结构上有显著不同。

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

结果 采用神经管植块法培养的神经嵴干细胞，免疫细胞化学染色呈现nestin及P75双阳性，将其接种在壳聚糖纤维支架材料上，可见神经嵴干细胞贴附于壳聚糖纤维上生长；S-100免疫细胞化学染色显示，S-100阳性细胞突起的末端呈扁平状膨大；扫描电镜显示，壳聚糖纤维上的躯干神经嵴干细胞为梭形，呈现"端对端"、"肩并肩"排列，伸出爪形伪足贴附于壳聚糖纤维上。

Spinous layer: the innermost prickle cells are polygon, and from the inside to outside, they become more and more flat, they are connected to granular cells with some space between, besides the spinous process, under normal condition, there is cell tissue fluid that could help the metabolism of cells in between.

棘层：棘细胞自里向外由多角形渐趋扁平，与颗粒细胞相连，各细胞间有一定空隙，除棘突外，在正常情况下，还含有细胞组织液，辅助细胞的新陈代谢。

The results by invert embedding TEM showed that higher invasive CCL229cells had vast of ER,which distributed throughout cytosol especially largeamount of vesicle-like and flatten cisternal rER in pseudopodia or cell processesand membranous flow-like structure from perinuclear region to pseudopodia,and less Golgi complex.

倒置包埋法常规透射电镜对人大肠癌细胞的超微结构观察结果显示，高侵袭力的CCL229细胞中内质网数量较多并呈全细胞分布，尤其在细胞伸出的众多伪足中含有丰富的小泡状和扁平囊样粗面ER结构，而且观察到由小泡形成的&膜流样&结构从核周一直深入到伪足中，但细胞中高尔基器少见。

The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.

结合触角电位、毛细管气相色谱、扫描电镜、透视电镜等技术对小线角木蠹蛾雌蛾腹尖末端不同组织部位提取物的测定分析以及腺体位置和形态结构的观察发现：小线角木蠹蛾性信息素分泌腺位于腹部末端8～9节之间，是一个由节间膜特化而成的上皮结构，为一可外翻的腹褶，腺体表面分布着饱满的锥形体，羽化后2天未交尾的雌蛾腺体细胞呈单层排列，腹面中央由密集的柱形上皮细胞组成，细胞排列向两侧延伸至背部，其形状由柱形逐渐变为扁平形，细胞核为椭圆形，细胞与细胞间有明显的胞连接，细胞基底膜基褶较多，质膜上分布着微绒毛，并与内表皮连接，内表皮上有多层几丁质，外角质层染色较深，细胞质中含有空泡、线粒体、脂质粒、粗面内质网和光面内质网。

RESULTS: Olfactory bulb-derived olfactory ensheathing cells adhered to the wall at 24 hours. Olfactory mucosa-derived olfactory ensheathing cells adhered to the wall at 4-5 days. The morphology of the two kinds of cells was similar. Most of them were bipolar and spindle-shaped, and few were tripolar and flat.

结果：体外培养24 h嗅球源性嗅鞘细胞即可贴壁，而嗅黏膜源性嗅鞘细胞多在培养四五天后贴壁，两种来源的嗅鞘细胞形态相似，以双极或梭形细胞为主，少量为3极及多突起形多级细胞，同时夹杂扁平、煎鸡蛋形细胞。

Results 1. HE: Without the effect of TSA, We found that the tracheal epithelium desquamated after 5-Fu treatment. The residual were trifle nude-nucleus cells distributed intervally on the basement membrane .

在有TSA作用情况下，去除5-Fu作用后0-12小时，基底膜上残留裸核细胞基本没有变化，但是数量稍有增加；24-48小时，裸核细胞消失，细胞成扁平状，细胞核变长，细胞浆伸展覆盖基底膜。

With the increase of cell density, soma was slenderer and slenderer and like fibroblast.② Growth curves of PDMCs: Growth latency ranged from 2 to 8 days after cell inoculation. During this period, adherence was observed gradually but not obviously amplified. Eight days later, cells entered log growth phase.

结果：①多分化潜能细胞的原代培养情况：胎盘组织消化后获得细胞中仅有少量的贴壁细胞，经两周后逐渐形成扁平单层细胞，呈漩涡状生长或成簇生长，随着细胞密度的增加，胞体变得细长，形态类似成纤维细胞。

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

结果表明，斑点叉尾鮰鳃的表面结构和微细结构与其他硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的扁平上皮细胞所覆盖，鳃弓表面细胞之间有孔洞；鳃耙基部较粗壮；中部鳃丝上皮细胞表面的微嵴两侧有细小的横突，有些微嵴出现融合或间断；端部和基部鳃丝上皮细胞表面的微嵴消失，形成密集颗粒状突起；鳃小片的高度和片间距较大。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
