The resultsshowed that malignant mesothelioma may be new histologic subtypes, including signet ringoidcell, small cell myxoid, myofibroblastic cell, lymphohistiocytoid, angioblastic cell and undifferen-tiated types.

结果发现，恶性间皮瘤新近的几种亚型有印戒样细胞型、小细胞型、粘液样型、肌纤维母细胞型、淋巴组织细胞样型、血管母细胞型和未分化型。

In resent year, several in vitro models for committed differentiation of ES cells have been described which give rise to a variety of cell types, including hematopoietic, neuronal, chondroitic, osteocytic, endothelial, myogenic, cardiac and smoothes muscle cells, but the committed differentiation into epidermal stem cells have not been reported.

ES细胞为研究基因功能、胚胎发生和个体发育，及组织细胞分化机理提供了理想的模型。近年来的研究表明，适当条件下，ES细胞可定向分化为三个胚层的各种类型的细胞，其中包括向神经元、造血细胞、成骨细胞、心肌细胞、血管内皮、软骨细胞、平滑肌特方向的定向分化。

As shown,the antigen is a glycoprotein present on the surface of cells. Extracts from Hep G2 hepatocellular carcinoma cells, HT-29 colon cancer cells, SKHep-1 liver adenocarcinoma cells, BT-20 breast cancer cells as well as U937 histiocytic lymphoma cells were positive for the precipitation of Ag-Ab complex, which were later reactive with the anti-3A5 McAb staining. While extracts from normal human endothelial cells showed no precipitation in Western blot.

抗原分子量为63kDa，是一种存在于细胞膜上的糖蛋白，在肝细胞肝癌Hep G2细胞，肠癌HT-29细胞，肝管癌SK-Hep-1细胞，乳腺癌BT-20和人组织细胞淋巴瘤U937细胞膜提取物中，均有此蛋白带，并能被单抗3A5特异性地识别，而人正常内皮细胞则不见此反应带。

BACKGROUND: Under different induction conditions, bone marrow mesenchymal stem cells can differentiate into the mesodermal tissues such as osteoblasts, chondroblasts, muscle cells, adipocytes and so on.

背景：骨髓间充质干细胞在不同诱导条件下具有向中胚层组织细胞如成骨细胞、成软骨细胞、肌细胞、脂肪细胞等分化的能力。

This experiment further investigated the possibility of differentiation of BMSCs in rats into neural stem cells in vitro, and into neural cells and neuroepithelial cells, so as to provide seed cells for cell transplantation of nervous system disease.

目的：已证实骨髓基质细胞可分化为中胚层组织细胞，实验予进一步探讨体外分离培养的骨髓基质细胞向神经干细胞分化的可能性，以及是否能继续定向分化为神经细胞及神经胶质细胞，为神经系统疾病细胞移植治疗提供种子细胞。

The two can cause ultrastructural pathogenesis widely in many organs and tissues such as hepar, pancreas, lien, ren, pulmo, cerebral, cerebellum, cor, muscular and so on, of them ,caused by i~olates YG97 and Y98 more obvious in epithelial cells of digestive tract and unobvious in epithelial cells of respiratory tract ,but ultrastructural pathogenesis caused by NDV strain F48E8 ,more obvious and more serious in glandularis and muscularis ventriaculi and in epithelial cells of respiratory tract .

将鹅源分离株YG_(97)、鸡源分离株Y_(98)和NDV强毒株F_(48)E_8感染SPF鸡，运用扫描电镜和透射电镜观察该二株病毒对机体细胞的影响，结果显示三株禽副粘病毒均引起机体肝、胰、脾、肾、肺、小脑、大脑、心和肌肉等实质器官组织细胞的超微病变，其中YG_(97)和Y_(98)引起消化道粘膜上皮细胞发生微绒毛脱落、纤毛脱落、分泌颗粒增多、细胞游离面破溃等显著的超微病变，引起气管粘膜上皮细胞的不显著超微病变；F_(48)E_8强毒株引起胃粘膜显著而严重的超微病变；还引起气管粘膜上皮严重的超微病变。

The callus started to produce near the surface of the wound from the remaining immature xylem cells including xylem parenchyma cells and xylem ray parenchyma cells...

愈伤组织由靠近伤口表面未成熟的本薄壁组织细胞和木射线细胞分裂产生，维管形成层在愈伤组织内层发生，且是一个渐进的过程。

Methods: BALB/c mice were intranasally infected with respiratory syncytal virus before or after sensitization to Japanese Cedar Pollen crude extract. Single-cell suspensions obtained from the lung parenchyma of inoculated mice were re-stimulated in vitro by co-cultivating with UV-RSV or JCP for 48 hr.

用花粉抽提物JCP致敏BALB/c鼠，致敏前或后经鼻感染RSV，提取肺组织细胞，体外培养，ELISA试剂盒检测培养上清中细胞因子水平；姬姆萨染色法分类并计数肺组织内浸润细胞数量；ELISA方法检测血清特异性抗体IgE水平。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
