Once the cells reached fluences of FBS coating on adhesive rats of MSCs: Some of the purified HUCB MSCs at logarithmic phase were growth curve of MSCs: The growth of cells were observed by phase contrast microscope (OLYMPUS CK40), and were detected by EPICS-ALTRA flow cytometry.

免疫表型：取扩增第5代的脐血间充质干细胞，用EPICS-ALTRA流式细胞仪进行检测。主要观察指标：①观察高糖组和低糖组细胞的生长状态。②观察不同时间点胎牛血清包被组与未包被组细胞的贴壁情况并分别计算贴壁率。结果：本实验总共培养和分析了70例脐血间充质干细胞样本。

The Tg for a mass ratio mixture of Galpi and sucrose of 0.3/1 was greater than 0 and was similar to that of the same ratio mixture of raffinose to sucrose, indicating that Galpi as well as oligosaccharides plays an important role in glass formation.

甲基肌醇半乳吡喃糖和蔗糖以0.3对1重量浓度混合比例，其玻璃质化转移温度在0℃以上，且近似於相同比例之寡糖类和蔗糖混合，显示甲基肌醇半乳吡喃糖和寡糖类在玻璃质化形成上扮演重要的角色。

The Chitinase of Saccharomyces cerevisiae(CTS1-2) is an Endochitinase which is endogenous in Saccharomyces cerevisiae. Its recognition and slipt site lies in the β-1,4 glucosidic linkage of homopolymer. Included in the amino acid sequence from N-terminal to C-terminal of the Saccharomyces cerevisiae chitinase are signal peptide sequence, catalytic domain, binding domain and a C-terminal shorten region.

The results show:(1) In testis, PNA receptors sites were firstly observed in the cytoplasm and plasma membrane of primary spermatocyte, and greatly increased in the plasma membrane of second spermatocyte, then decreased and were accumulated in the tail of the round spermatid. The same reaction was observed in sperms of testis and spermatheca, which shows stronger reaction in head and weaker in tail. A universal dyeing was observed on the plasma membrane of sertoli cells.

结果表明：(1)在中华蚱蜢的精子发生中，PNA受体是由初级精母细胞合成，然后转移到膜上，在次级精母细胞，由于量的积累其质膜出现了强阳性标记；从早期精子细胞到成熟精子时期糖蛋白的分布发生了明显的修饰变化，这些变化与精子获得与卵子进行识别、粘附、结合等受精能力密切相关：受精囊内与精巢内的精子表面的标记是相同的，说明质膜糖蛋白的修饰作用在精巢内就已完成。

In this paper, an escherichia coli-saccharopolyspora erythraea shuttle vector containing the erya promoter region was constructed using the enhanced green fluorescent protein gene as a reporter. the shuttle plasmid was transformed into sac.erythraea a226 and streptomyces lividans jt46 by peg mediation, respectively. fluorescence microscopy confirmed that the egfp was expressed in both strains.
