不分化的

As similar defects are not exhibited by mice that experience systemic inhibition of NF-B, we postulated that the morphogenetic defects in IKK--deficient mice are not caused by reduced NF-B activity but instead are due to failed epidermal differentiation that disrupts proper epidermal–mesodermal interactions.

因为类似的缺陷没有出现在经历了全身NF-B抑制的小鼠，作者推断IKK缺失小鼠的形态发生缺陷不是由于NF-B活性降低引起而是因为可以破裂专属表皮－中胚层相互作用的表皮分化失败引起。

The results showed that:(1) Many proliferating cells were distributed unevenly in the ventricular zone of telencephalon, and the [3H] labeled cells were found to be populated in the lateral ventricular zone of neostriatum at brain level L12~L14,forming proliferation "hot spots";(2) Having underwent mitosis twice, the proliferative cells in the VZ began to migrate laterally 6 days after intramuscular injection of [3H] thymidine, and these migrating precursor cells terminated at their targets and differentiated into new neurons on the 30th day.

结果发现：①端脑室带区中存在不均匀分布的[3H]标记细胞，大量标记细胞分布在端脑尾侧新纹状体水平(L1～L14)的VZ，形成标记细胞的&热点&区；②标记细胞经两次有丝分裂后，大约在肌肉注射[3H]的第6天后开始从VZ向外迁移，在30天左右到达目的脑区并分化成为成熟神经元。

A few nonadherent cells in the culture system couldn't interfere in the generation of DC. The structure of"veil"of DC made of graded dendritic projections twiested enlarged the area of membrane and became the foundation of structure to capture antigens.

四、结论： 1。该方法可以诱导出的成熟DC细胞，形态典型，而且少量悬浮细胞不影响DC细胞的分化和成熟；&面纱&状结构是由多级树突状突起相互缠绕形成，扩大了DC细胞的膜结构，是有效捕获抗原的结构基础； 2。

The results showed that HGF not influenced the proliferation and osteogenic differentiation of bone marrow-derived mesenchymal stem cells.

结果表明，重组人HGF不影响骨髓间充质干细胞的增殖和向成骨细胞的分化，但可明显促进骨髓间充质干细胞的迁移并抑制anoikis诱导的细胞凋亡；PI-3K和MAPK途径参与了HGF促进细胞迁移的作用。

The cultured cells appeared morphologically as spindle-shape and the average number of colonies which form in primary culture was 43±11. MSCs were positive for CD44 and CD29 but negative for CD34, CD45 and HLA-DR with a phenotypical identity of 99%.

上述结果表明，通过密度梯度离心方法分离培养的细胞不是骨髓造血干/祖细胞，而是一群形态和表型均一的间充质干细胞，具有独特的增殖和表型特征及较强的分化潜能。

The Hedgehog morphogen governs cell differentiation and proliferation in a diverse array of patterning events in many animal species, ranging from insects to mammals. The seven-transmembrane protein Smoothened transduces the HH signal across the plasma membrane but molecular mechanisms of its activation are poorly understood. Zhao et al .

Hedgehog形态发生素在从昆虫到哺乳动物在内的很多不同动物物种的各种不同成形事件中决定细胞的分化和增殖。7-跨膜蛋白Smo跨越胞质膜传导Hh信号，但科学家对Smo激发的分子机制却很不了解。

The changing government supply preference was a kind of exogenous force to promote economic transition , while it is endogenized by the transition process itself now.Endogenous or exogenous interest groups and social groups emerged with the transition process, meanwhile public resources were fragmentized among government agencies and out of control of fiscal administration.

立足于经济市场化过程中利益集团的出现和社会群体的分化这一事实，立足于公共资源被政府机构、部门肢解而不能实现财政统筹和公共财政转型这一事实，我们利用简单的模型说明了政府规模、结构是如何在政治均衡而非经济均衡中被决定的，以及这一均衡的效率属性。

By means of his works, Flaubert criticizes and satirizes the French capitalist class bitterly at that time, thinks and explores the realistic living conditions. Therefore, there exists class awareness in his works obviously. Meanwhile, he is aware of class division and inequality in society, so his ideas have the marked humanism.

福楼拜通过创作，辛辣地批判、讽刺了当时的法国资产阶级社会，思考和探索了当时人类的现实生存状况，明显地带有阶级意识，同时他也意识到了社会中阶级的分化与不平等，他的思想带着鲜明的人道主义精神。

The two species are similar in stomatal character and in the absence of accessory transfusion tissue, but they are very different in stomatal distribution, pinna venation pattern and pinna marginal shape, presence or absence of mucilage canal, differentiation of palisade and spongy parenchyma, characteristics of girder parenchyma and epidermal anticlinal wall.

两个属在气孔器特征与不具副传输组织方面极为相似，而在气孔的分布、羽片脉序式样与叶缘形态、粘液道的有无、海绵组织与栅栏组织的分化、工字厚壁组织与表皮细胞垂周壁特征方面则有较大的差异。

This policy, say his critics, is polarising his church, though more so in the rich West than in the developing world where Catholicism continues to grow (but not necessarily in the way that the pope wants; see article).

批评他的声音说，这一政策使他的教会两极分化，但和继续增长的天主教发展中国家相比西方国家更是如此（但不是教皇希望的方式；见文章）。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
