细胞发生

Experimental results show that there are existing some indifferent mechanisms to the pollen sterilization of the Ms types: during the period of single nucleic to three nucleic pollen cell,we observed that the cell of xylem and phloem in anther septum abnormally developed,also the cell in the sheath of vascular bundle,smaller and arranged irregularly; the metabolic block developed too,es...

结果表明，不育类型的花粉败育有着一些共同的机理：在花粉单核期至三核期可见到花药隔维管束的木质部及韧皮部细胞发育较差，维管束鞘细胞发育不良，体积较小，排列紊乱；在单核花粉期至三核花粉期均发生物质代谢障碍，特别在花药部位尤为明显；由于维管束发育不良和花药物质代谢障碍，导致了花粉缺乏营养而败育。

But embryo got through 2-cell block after H2O2 treatment occurred compensatory growth in later development, there were no differences with the embryo cell number and the cleavage index compared with normal developmental embryo.

但是经H_2O_2处理之后渡过2-细胞期阻滞的胚胎能在以后的发育中发生补偿性生长，其胚细胞数和分裂指数都和体外正常发育的胚胎没有差异。

Patients who responded clinically also had a change in the ratio of CD4+ T cells to CD8+ T cells 30 and 90 days after treatment.

在治疗的第30天和第90天，获得临床改善的患者，其体内CD4+ T细胞和CD8+T细胞的比值发生了改变。

These results suggested that some cytokines alone or in combination might be the activators of lymphocyte adhesion in inflammation.

综合以上结果，我们推测：炎症发生后，淋巴细胞首先具备了与ECM粘附的潜能，这种潜能可能是细胞粘附分子的表达发生了变化。

Nuclear trans location of the subunit p65 and p50, was observed by indirect immunofluorescence assay when fibroblast-like synoviocytes were respectively stimulated by 10^(-4) Mol/L E for 1, 2, 4, 8 and 24 boors. Results: E induced the nuclear translocation of p65 at 4, 8 and 24 hours.

结果：荧光显微镜观察染色的滑膜细胞，发现E2处理4、8、24h的滑膜细胞p65发生了核转位，其转位率分别为68%、95%和52%，在8h时达到峰值。

The BTSCs attached to poly-L-lysine-coated coverslips and differentiated when the serum-supplemented medium was added.

在含血清培养基中脑肿瘤干细胞发生贴壁分化，产生具有多种细胞形态的分化细胞。

CAM-1–targeted but not control microbubbles attached to cultured endothelial cells, although firm attachment at the highest shear rates (8 to 12 dynes/cm2) occurred only in pulsatile flow conditions.

尽管与仅在血液流动状态下发生的以最高剪切压率(8 to 12 达因/cm2)紧密联系，但靶向血管细胞粘附分子-1 (CAM-1)并没有控制与培养内皮细胞相关微泡斑块。

The characteristics of these effectors, which might be associated with hepatocellular carcinoma, are also discussed.

同时探讨了细胞因子的特性及其在肝细胞癌发生发展中的作用。

Ocean Rhodotorula is a single cell eukaryon biology, and cannot the movement, commonly the cell assume the cylinder, the ellipse or the circular generally, the cell long approximately 3-10um, wide approximately 15-5.5um, its shape and the size are raised the cultivate condition and the raise time will influence occur frequently the change, its colony is the pink.

海洋红酵母为单细胞真核生物，不能运动，细胞一般呈圆柱形、椭圆形或圆形，细胞长约3～10um，宽约15～5.5um ，其形态和大小受培养条件和培养时间的影响常常会发生改变，其菌落为粉红色。

The development of the calli and single few-celled aggregates was observed through paraffin sections.The results revealed 5 pathways of embryogenic calli origination including origination from both ends of hypocotyls,origination in inner,differentiation from non-embryonic cells,origination from outer cells of calli,and origination in the surrounding of gland.

以陆地棉品种Coker 201下胚轴为外植体诱导愈伤组织，并以介于30-50目筛之间的胚性愈伤细胞团为材料进行单个细胞团培养，采用石蜡切片法观察棉花愈伤组织诱导和分化过程及体细胞胚发生和发育过程。
