再分化

We can think about is how the formation of polarization?

我们再想一想，两极分化是怎么形成的？

The results showed that Mephitinae was divided from Mustelidae firstly,and then the remain were divided into two branches.Martes species and Wolverine were contained in one branch which was formed a sister group with Eurasian badger of Melinae;Lutrinae species and Polecat of Mustelidae formed a sister group,and Marbled polecat was sister to the clade of Lutrinae species and Polecat.They formed another branch.Eurasian badger has the closest relationship with the Sable of Martes,and Lutrinae has the closest relationship with Mustelidae.

以狼为外类群，应用邻接法构建鼬科线粒体控制区全序列的系统进化树，结果表明：臭鼬亚科最先从鼬科中分化出来，随后剩余类群分为两大支系，即貂属种类与貂熊聚为一支，并与獾亚科的狗獾形成姐妹群；另一支为水獭亚科的物种与鼬属的林鼬形成姐妹群，再与虎鼬聚在一起，狗獾与貂属的紫貂亲缘关系最近，水獭亚科与鼬属亲缘关系最近。

Methods The cell suspensions of human gastric poor differentiated mucinous adenocarcinoma, MGC-803, were inoculated into nude mice subcutis.

将人胃低分化粘液腺癌MGC-803细胞悬液先在裸小鼠皮下接种成瘤，再取瘤组织块分别接种到裸鼠的皮下、胃壁上，分早（＜20天）、中（20～40天）、晚（＞40天）3个阶段观察移植瘤的生长及侵袭转移情况。

The results of changes of endogenous hormone contents at early stage of floral differentiation in cotyledonary nodes of cucumber seedlings after decapitation were as follows: The contents of IAA and ZT in cotyledonary nodes of the cucumber seedlings withi...

ZT/IAA、GA3/IAA比值的变化趋势相似，0至2天上升，2至3天下降，3至4天再上升。根据实验结果，联系黄瓜去顶苗成花的形态变化过程，对激素质量分数变化与花芽分化之间的关系进行了讨论。

The main results are listed as following: 1. Phylogeographic study on Croomia The relationships and distribution of cpDNA haplotypes suggested that Croomia had been widely distributed in ancient eastern Asian and northern American; the origin and distribution center of Croomia were concentrated on the mountains comprised Mt.

Croomia亲缘地理学根据叶绿体DNA(trnL-F、atpB-rbcL)单倍型的关系和分布推测，Croomia在古欧亚大陆和古北美大陆有着较广泛的分布；我国的黄山和天目山一带是Croomia的分布、起源中心，其散布路线是从中国大陆到日本，再到美洲古大陆；北美种群与东亚种群分离较早；东亚种的分化时间比较晚。

We derived cell populations with properties of ectodermal and mesenchymal cells in 2D culture and incorporated these divergent cell populations into 3D epithelial tissues.

我们利用二维培养将胚胎干细胞分化为具有外胚和间充质特性的细胞，再将这些细胞复合入三维上皮组织。

Results (1) Primary callus came into being 3 days after operation. Mesenchymal cells from peripheral tissues around the primary callus were differentiated into chondrocytes 1 week later. Endochondral ossification was going on then. Bridging callus was formed in the fracture sites 4 weeks after operation.

结果 (1)伤后3 d开始形成原始骨痂。1周时肉芽组织中的间质细胞开始分化为软骨细胞，软骨形成后再进行软骨内化骨。4周时形成连接骨折端的桥接骨痂。

Recently, a new pluripotent stem cell establishing method was reported that, mouse and human differentiated cells could be induced reprogrammed into a pluripotent state by expressing exogenetic stem factors such as Oct4, Sox2, et al, through retroviral transduction.

通过反转录病毒载体系统，在小鼠和人类高度分化细胞中表达干细胞因子Oct4， Sox2， Klf4和/或c-Myc等基因，再经过干细胞标志因子Nanog或Oct4筛选，可以获得与ES细胞特性十分近似的诱导多能干细胞系。

Follow-up (10 patients) showed 7 dead of disease, 1 alive with disease, and 2 disease free. Four atypical lipomatous tumors were seen including 2 with low-grade dedifferentiation.

随访了10例，7例死于此肿瘤、1例伴病存活、2例无再发存活。4例肿瘤为非典型脂肪肿瘤，其中2例伴低级别的去分化成分。
