成骨细胞的

The histiological characteristcs, and activities of alkine phosphatase and acid phosphatase of the implantan were examined to study the effects of fluoride on biological activities of BMP.

结果 氟对BMP的生物活性有直接的影响，氟能促进BMP将更多的成纤维细胞转化为成骨细胞，并能增强成骨细胞的功能，加速钙盐沉积，而破骨细胞功能有所下降。

Then the concentration of NO in supernatant of culture and the changes in histomorphometry were examined.

体内NO主要来源于成骨细胞及骨髓细胞[3] ，而骨髓基质细胞是成骨细胞的主要来源。

The responses of osteoblasts to both agents can be as the characteristics of primary osteoblast derived from rat calvaria.

这些成骨细胞对上述两种药约之反应也可作为由大鼠头颅骨所取出之成骨细胞的特性。

Objective To study the method of inducing human marrow mesenchymal stem cells into osteoblasts directionally and to identify osteogenesis characteristics.

目的：探讨将成人骨髓间充质干细胞定向诱导分化为成骨细胞的方法，并对所诱导细胞的成骨特性进行鉴定。

Emerging evidence indicates that both osteoclastic activity and osteoblastic activity are required for the development of prostate cancer bone metastasis.

愈来愈多的证据显示，破骨细胞和成骨细胞共同参与了前列腺癌的骨转移，调节破骨细胞和成骨细胞的细胞因子影响前列腺癌细胞的发展与转移。

The effect of PTH on the osteoclastic bone resorption,and how the osteo-blasts mediat the reaction was studied in vitro by using the method of isolating and cul-turing rabbit osteoclasts and osteoblasts.

采用分离、培养兔破骨细胞和成骨细胞的方法，体外研究甲状旁腺激素对破骨细胞骨吸收功能的影响，以及成骨细胞和破骨细胞之间的相互作用。

OBJECTIVE: To investigate isolated culture and conservation method of human periosteal osteoblasts, in addition, to observe the biological characteristics.

目的：建立人胚胎骨骨膜来源成骨细胞的分离培养、保存方法，观察骨膜来源成骨细胞生物学特点。

Methods Periosteal cells were isolated and cultured in vitro and then exposed to dexamethasone 10 -8 mol/L, 10 -7 mol/L an...

利用多种细胞因子促进细胞向成骨细胞的分化，以保证细胞在植入体内后能够保持并充分发挥其成骨活

Methods: The human osteoblasts were isolated from the trabecular bone by ...

结果：所分离培养的细胞具有成骨细胞的形态特征，保持了其在体内的功能；MG63细胞株和人成骨细胞均表达PRA和PRBmRNA和蛋白质。

Then PLGA Micro spheres can promotes the proliferation of osteoblast in a long perlod because of the controlled release of bFGF from microspheres. The PELA microspheres satisfied the proprty reguirement of controlled release, but the biological activity of the released bFGF is partially destroyed.

2体外细胞试验中，游离bFGF对成骨细胞具有促分裂增殖的作用，但效应期很短；而PLGA微球通过持续释放活性bFGF，可在较长时期内促进成骨细胞的分裂增殖；PELA微球虽然达到了缓释的性能要求，但释放出的bFGF的生物活性受到了破坏。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
