Recently, proteolytic cleavages of CD44 have been emerging as key regulatory events for the CD44 undergoes sequential proteolytic cleavages in the ectodomain and intramembranous domain, resulting in the release of CD44 intacellular domain (CD44 ICD) and it's cleavage plays a important role in tumor cell migration.

先前的文献指出，乳癌细胞株会表现大量的CD44，且CD44的切割在癌细胞的移动上扮演一个重要角色。

In this study, a new horizontal microinjection system has been established to solve these problems. Because the average time per pronuclear embryo by microinjection has been significantly shortened with the horizontal system, the cleavage rate and 16-cell rate of those microinjected embryos increased markedly.

为了解决这些问题，本研究有针对性地设计了新型的水平微注射系统，利用此系统，可明显缩短常规注射原核胚的平均时间，注射后原核胚的分裂率、8-16细胞胚胎发育率也明显提高。

After treatment with AT9810,the cell became smallerand condensed,typical signs,such as cytoplasmicconcentration,chromatin agglutination,pyknotic necleus,necleus cleavage,apoptosis corpuscle,was found inmorphological observation.

经AT9810处理后的细胞体积变小皱缩，形态学观察具有典型凋亡细胞的特征：胞浆浓缩，染色质凝集，核固缩、裂解及凋亡小体形成。

In this manner, the replicative senescence is avoided due to the rapid cleavage rate of the cell line.

其中，H1299缺少了老化常有过度表现的p53基因，在此也可探讨p53基因的有无，是否对细胞的老化造成影响。

METHODS: The breast cancer cell lines Bcap37 were treated with different concentrations of vinblatine dissolved in dimethyl sulphoxide or caspase-3 inhibitor (DEVD-CHO, 100 μmol/L) for 3 h. The changes of the proliferation were detected by MTT methods. The apoptosis was determined by observing the internucleosomal DNA cleavage and PI staining, and the proteins of pro-caspase-3 and IκΒ-α were detected by Western blotting methods.

用二甲基亚砜对照、100μmol/L caspase-3抑制剂预处理乳腺癌Bcap37细胞3h后，加入不同浓度的长春碱，以MTT法检测肿瘤细胞增殖能力，以细胞DNA片段分析及PI染色法检测肿瘤细胞凋亡，以蛋白免疫印迹法检测pro-caspase-3和IκΒ-α蛋白的变化。

Then we compared cleavage rate and blastocyst rate among different groups. After that we evaluated the quality of blastocysts by using ICM/TE (Inner cell mass/Trophectoderm cells) ratio via staining with propidium iodide and Hoechest333258, and analyzed the level of genome methylation and histone acetylation by immunofluorescence.

比较各组受精卵的卵裂率和囊胚发育率；并应用碘化丙啶和Hoechest333258对囊胚进行染色，利用ICM/TE值评价各组胚胎体外发育的质量；同时将囊胚进行免疫荧光染色，观察其基因组甲基化和组蛋白乙酰化的水平。

In mammal and bird species the fate of cells is determined by the position of a cell late in cleavage.

对哺乳动物和鸟类而言，细胞的命运最终由细胞分裂后所处的位置决定的。

OBJECTIVE: To explore the feasibility of establishing a new human embryonic stem cell lines using frozen cleavage human embryos.

目的：探讨利用冷冻胚胎建立人类胚胎干细胞系的可行性。
