向细胞的

Regression of a specialized cell or tissue to a simpler, more embryonic, unspecialized form.''.'Dedifferentiation'.

去分化，反分化指高度分化的细胞或组织向更简单，更初期非特化的形式的退化。

Bone induction is an important theory in the early 20th century. Urist found that bone morphogenetic protein could promote mesenchymal cell to differentiate into osteoprogenitors and chondroblast in 1965, thence many scholars went in for the significant work in this research field.

诱导成骨是近代发展的重要理论，Urist首先提出间充质细胞在骨形态发生蛋白的作用下可向成骨和成软骨方向分化，此后国内外很多学者在该领域进行了广泛深入的探索。

Objective: To examine the property and proliferation ability of primary culturing MSC, investgate the effect of lightly centrifugation and chemical definition medium to induce MSC differentiate into chondroblast.

目的：了解骨髓基质干细胞原代培养的特性及增殖能力，探讨轻度离心和化学限定培养基法诱导骨髓基质干细胞向成软骨方向分化的作用；为软骨组织工程提供足量、合适的种子细胞。

The IFN-γ immunoreactive cells and dendrites with higher density were detected in the Ⅰ,Ⅱ and Ⅲ layer of whole spinal cord,the lumbosa sacral parasympathetic nucleus dorsal commissural nucleus,the Ⅸ laye...

中间带和腹角内的阳性胞体的树突还伸向外侧索和腹索，有时可达脊髓边缘。本试验证明了 IFN-γ在腰骶髓段脊髓内的分布，从而在细胞水平为&免疫神经内分泌网络&学说提供了形态学依据。

Molecular detection in peripheral blood at surgery suggests that hematogenic tumor cell dissemination is a common and early event and that surgical manipulation enhances this release of tumor cells into the circulation.

血循环中癌细胞的存在是大肠癌的一种常见的早期事件，手术刺激可增加肿瘤细胞向血循环中释放。

Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，部分周围型胆管细胞癌的CT表现肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

Paratonic movements Movements of plants or plant parts in response to external stimuli.They may be divided into mechanical movements(e.g. the hygroscopic movements of dead cells)and movements caused by the stimulation of sensitive cells(e.g. tropisms and nastic movements).

感性运动：指植物或植物的某部分队外界刺激所作出的反应运动，可以被划分为机械运动和刺激敏感细胞所引起的运动（如：向性运动和感性运动）。

Moreover, over-expression of the constitutively activated Notch1 intracellular domain also inhibited odontoblastic differentiation of DPSCs.

组成性激活的Notch1胞内段的过表达也抑制了DPSCs的成牙本质细胞向分化。

By investigating the regeneration feasibility of mesenchymal stem cells,which is derived from endothelial and subendothelial cells of human umbilical vein,to neuron-like cells in vitro,we want to provide new evidence for the transplantation of hUV-derived MSCs to nervous tissue.

探讨来源于人脐静脉内皮及内皮下分离的间充质干细胞向神经元样细胞分化的可能性，以期为脐静脉MSCs的神经移植提供理论依据。

The latency of the waves of SEP or MEP is extracted. But it still is the best in all. The control group is the worst of all. The wave can be found again after the spinal cords are hemisectcd in control group. 5.. Seen from the immunohistochemistry of NF, Schwann cells can promote neural dendrite outgrowth toward the area of hemisected spinal cord.

神经纤维的兔疫组化染色脊髓半切损伤后，经NF的免疫组织化学技术染色显示：移植雪旺细胞可以促进神经纤维向脊髓损伤区域生长，抗体封闭 LI后神经纤维的生长受到抑制，再生神经纤维数相对减少，这从免疫组织化学方面说明口对神经再生具有影响。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
