不典型性增生可累及外阴上皮，右侧为表层的过度角化，左侧为萎缩的角化的鳞状上皮。

Some changes of phenotype occur in these cells. Our results provide data for further studying the mechanism of immortalization and the establishment of a human nasopharyngeal epithelial cell line.

这些研究资料为进一步阐明上皮细胞永生化的分子机制、建立人鼻咽上皮细胞永生化模型提供实验依据。

Results 1.VEGF-C expression and MVD in epithelial ovarian carcinoma were higher than those in normal ovarian tissue (P.05),TSP-1 expression were lower than those in normal ovarian tissue (P.05);2.In epithelial ovarian carcinoma tissue,VEGF-C expression and MVD increasing according to progression of the FIGO phase but TSP-1 expression decreasing according to progression of the FIGO phase.

结果 卵巢上皮癌中VEGF-C表达及MVD均明显高于正常卵巢组织(P.05)，TSP-1表达低于正常卵巢组织(P.05)；卵巢上皮癌组织中，VEGF-C表达及MVD随国际妇产科联盟分期的进展而增高(P.05)，TSP-1表达随FIGO分期的进展而降低(P.05)。

The production of human alpha lactalbumin was 0.64 g/L approximately. The results indicate that the bovine mammary epithelial cell line have the ability of expressing exogenous gene, the 5′ flanking sequence of bovine αS1 casein gene has the effect of regulating gene expression specifically and the vector αS1-LA-psv which was constructed can coexpress alpha lactalbumin and β-galactosidase.

SSEA-1and Oct-4 were not detected at the protein nor the mRNA level in the limbus and cornea.

免疫组织化学法和RT-PCR均显示SSEA-1和Oct-4不表达与角膜缘上皮和角膜上皮。

Results一. Culturing and identification of human conjunctiva cells1. morphous of conjunctiva cellsCells were harvested by tissue cultivation after digestion. Ponderosus cells adhered after 48 hours. Cells were shown in shape of round, ellipse and polygon. Cell body was loose and lucency with nucleus in center, cell membrane was also clearly seen. Cells were arranged in inlay and fuse in film after 12-14 days.2. Immunochemistry testNomogeneous immunochernical positive granules against CK13 were observed in endochylema of human conjunctiva cells.3. growth curve of conjunctival cellsSubcultured cells were aged and feeble after 5th passage.

结果一、正常人结膜细胞的培养与鉴定1、活体细胞的形态消化后组织块培养法：48小时后见大量上皮细胞贴壁，细胞不规则呈圆形、椭圆形、多边形，细胞体肥大透亮，细胞核位于中央，胞膜清楚，约12-14天后细胞呈镶嵌状排列，融合成膜状。2、免疫组化鉴定培养的人结膜上皮细胞CK13免疫组化染色见阳性颗粒均匀分布于胞浆中。3、培养结膜细胞生长曲线传代培养多数样本于P5代以后开始出现衰老征象。
