AIM: The effects of nerve growth factor on the proliferation andcell cycle of human dental papilla mesenchyme cells were detected to evaluate its possible roles in tooth development.

目的：观察神经生长因子对人牙乳头间充质细胞增殖和细胞周期的影响，探讨其在牙胚生长发育过程中的可能作用。

It was needed only 20-30 minutes; the active components can be transformed into high concentration active substances, nonstop to the deep skin, the active components infiltrate to Subcutaneous tissue through the channels among Hair follicles, sweat glands and cells, reach the mesoblast .then it open the entrance easily by stimulating the water channels protein on the cell membrane, infiltrate the cell membrane, make the skin cells to absorb nutrients plenary.

需20-30分钟即可将活性成分快速转换成高浓度的活性物质，直达深层皮肤；利用"水电泳"技术，活性成分通过毛囊、汗腺与细胞间通道渗透皮下组织，达到中胚层通过刺激细胞膜上的"水通道蛋白"，轻易打开入口，渗透细胞膜，使皮肤细胞充分吸收营养成分

Fibroblasts are mesenchymal cells which are derived from the embryonic mesoderm.

成纤维细胞是胚胎中胚层起源的间充质细胞。

Objective: To investigate the nephrotoxicity of plumbagin on human embryonic kidney cell 293 in vitro and protective effects of acid fibroblast growth factor on the cells.

目的：观察白花丹素在体外对人胚肾细胞293的毒性，以及酸性成纤维细胞生长因子对白花丹素所致肾损伤的保护作用。

During morphogenesis cells and cell populations change shape: an exampleis neurulation in vertebrate embryos, in which the edges of the flat neural plate fold upward and fuse, forming the beginnings of the hollow brain and spinal cord.

在形态发生期间，细胞和细胞群体形状发生改变：例如，脊椎动物的神经胚，扁平神经板的边缘向上折叠并融合，是中空大脑和脊髓神经形成的开端。

During segmentation,GFP was detected in the notochord but not in the foor plate.

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；在体节形成期，GFP在脊索细胞中表达，但未发现在神经底板细胞中表达。

The expression of TRAF6in cultured cell line MDPC-23was determined at protein level,it intimated that TRAF6may be a new found signal factor which participates in the progress of odontoblast development and mineralization.

因此，我们认进一步研究TRAF6在成牙本质细胞和成釉细胞中的表达和功能，揭示TRAF6在牙胚发育和矿化中可能起到哪些重要作用十分必要。

Both DPSCs and DPMCs had the expression of DSPP gene after 7Key words: Dental pulp stem cells ; Dental papillae mesenchymal cells ; Odontoblast

DPSCs是一种较为理想的牙胚问充质细胞的替代细胞，在适宜的诱导环境中能够替代DPMCs进行牙齿的再生研究。

The effects of auxins and cytokinins on the process of somatic embryo genesis and embryoid growth of Oxalis traingularis A.St.Hil. by Tissue culture were studied.

通过组织培养方法，探讨生长素和细胞分裂素在紫叶酢浆草体细胞胚诱导和发育过程中的作用。

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。
