Cytokeratin, vimentin, alkaline phosphatase,α-actin,Ⅷ Ag, fibronectin and desmine were determined using the third generation cells. The ultrastructure were examinated by the transmitted and scanning electronic microscope.

取第三代细胞检测细胞角蛋白、波形蛋白、碱性磷酸酶、结蛋白、Ⅷ因子、α-肌动蛋白的表达，应用扫描电镜和透射电镜观察细胞的超微结构。

Chloride channels have been identified in vasucular smooth muscle cells. These channels have been shown to be involved in myogenic tone regulation and neuromuscular transmission in various vascular beds. However, whether the chloride channels are responsible for the formation of excitatory junction potentials of the smooth muscle cells in the spiral modiolar artery remains elucidated.

许多研究已证实，血管平滑肌细胞膜上存在氯离子通道，进一步研究发现氯离子通道不仅参与调节平滑肌细胞的肌原性紧张，而且参与了许多种类血管床的神经平滑肌细胞之间的信息传递，但Cl-通道及氯离子通道阻断剂对耳蜗螺旋动脉细胞兴奋性接头电位(excitatory junction potential，EJP)是否有影响，目前还不清楚。

Cytology revealed 3-dimensional groups of ductal cells in a background of myoepithelial cells and stromal cells, consistent with a fibroadenoma.

对该肿块进行细针抽吸活检，细胞学显示以肌上皮细胞和基质细胞为背景的三维导管细胞结构，与纤维腺瘤结构一致。

The immunocytochemistry was used to identify the RASMC.RESULTS: The RASMC were successfully cultured by the adherent method of tissue explants and grown in the "peak- valley" mode. The cultured RASMC were fusiform shape with a big oviform or round nuclei rich in cytoplasm. Immunohistochemical method ( S-P method) showed strong expression of a- smooth muscle actin.

结果：组织块贴壁法成功培养出SD大鼠胸主动脉平滑肌细胞，培养的细胞呈典型&峰-谷&样生长，HE染色细胞呈梭形，胞浆丰富，核大而圆或椭圆，免疫组化S-P法检测a-平滑肌肌动蛋白单克隆抗体呈强阳性表达。

Signalling through CXCR4 mediates actin polymerization and pseudopodia formation in cells, and induces chemotactic and migration to target organs. In addition, CXCR4-SDF-1 axis can promote tumor angiogenesis and growth.

CXCR4在肿瘤组织中的表达明显高于正常组织，而肿瘤常见转移部位均为CXCR4的配体基质细胞衍生因子-1(stromal cell derived factor-1，SDF-1)表达丰富的器官，SDF-1与CXCR4结合后可使细胞肌动蛋白丝聚合，形成伪足，从而定向诱导肿瘤细胞迁移到特定的靶器官；此外，CXCR4与其配体SDF-1相互作用可以促进局部新生血管作用，利于肿瘤生长。

A reduction in actin expression was observed by immunoblotting in both nucleus pulpous and anulus fibrous cells, especially in nucleus pulpous cells.

Western免疫印迹结果显示，肌动蛋白在纤维环细胞和髓核细胞中的表达均明显减少，以髓核细胞为著。

Laboratory of Gellular and Molecular Biology, Shaaghai Medical College, Fudan University, Shanghai 200032, ChinaAbstract:Objective Using sodium N-lauroyl sarcosine as new decellularization reagent to prepare decellularized matrix for tissue engineering purpose.

吴春根 王松梅高红阳潘銮凤复旦大学上海医学院细胞与分子生物学实验室，200032摘要：目的尝试用十二烷基肌氨酸钠作为脱细胞试剂，制备脱细胞组织工程支架材料，并分析其生物学性能。

Results After 2 or 6 hours of LPS intravenous administration, severe lung injury and positive signals of NT occurred with the latter located in the pulmonary macrophages, endothelia, subendothelial and muscular layers of the pulmonary artery.

结果 LPS静脉注射2 h和6 h 后，肺脏有明显损伤及硝基酪氨酸产生的阳性信号，该信号主要分布于肺泡壁巨噬细胞、肺小血管和细小支气管周围的巨噬细胞以及部分肺动脉的内皮细胞、内皮下层及肌层。

Motilin and gastrin induced contraction of isolated gastric smooth muscle cells in a dose-dependent manner.(2) Motilin- and gastrin-induced antral smooth muscle cell contraction was inhibited by antibodies against Gαi-3. Motilin and gastrin caused an increase of Guanosine-5′-(3-［35S］thio)triphosphate(［35S］GTPγS) binding of Gαi-3.(3) Contraction of antral muscle cells induced by motilin and gastrin was inhibited by the phospholipase C inhibitor U-73122 and the IP3 receptor antagonist heparin.

结果显示：(1)胃动素和胃泌素对胃窦平滑肌细胞均有收缩作用；(2) Gαi-3抗体可抑制胃动素和胃泌素加强胃窦平滑肌细胞的收缩，胃动素、胃泌素明显增加Gαi-3抗体与［35S］GTPγS的结合；(3)磷脂酶C抑制剂U-73122、三磷酸肌醇受体拮抗剂肝素可抑制胃动素和胃泌素引起的胃窦平滑肌细胞的收缩。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
