Objective To study the effects of fluoride on expression of calmodulin in rat osteoblasts cultured in vitro in different doses and at different time.

目的 观察不同浓度的氟在不同时间段对体外培养大鼠成骨细胞的钙调蛋白的影响。

Results When the osteoclasts were cocultured with primary osteoblasts, the growth of osteoblasts had more preponderances.

成骨细胞对破骨细胞分化及功能成熟的影响与两者的相对数量有关。

Methods The composite was cocultured with osteoblasts derived from human bone marrow stem cells.

人骨髓间充质干细胞诱导法培养成骨细胞，并鉴定。

Group B: The muscle was implanted by tissue engineered bone produced by MSCs cocultured with HA.

RGD多肽表面修饰对以HA为支架材料组织工程骨的异位成骨有明显优化作用。

MethodsThe composite was cocultured with osteoblasts derived from human bone marrow stem cells.

人骨髓间充质干细胞诱导法培养成骨细胞，并鉴定。

Op-HA/PLGA and PLGA chloroform solution were covered on the surface of coverslip of which rabbit osteoblasts were inoculated and cultured in vitro for 7 days.

将op-HA/PLGA和PLGA氯仿溶液分别于盖玻片表面铺成薄膜，并接种兔成骨细胞，体外培养7 d。

Septum bore of Transwell double-layer cell culture plate was 0.4 μm. In the co-culture group, osteoblasts were incubated in the upper chamber. In the control group, osteoblasts were not incubated in the upper chamber. Bone marrow mesenchymal stem cells were incubated on the pretreated coverslip in the lower chamber in both groups, for 20 days.

Transwell双层细胞培养板的隔膜孔径为0.4 μm，共培养组于培养上室接种成骨细胞，对照组培养上室未接种细胞，两组培养下室均于预处理的盖玻片上接种骨髓间充质干细胞，培养20 d。

It is further confirmed by the experiment of muti-inducement that MSMPs can differentiate into osteocyte sand fibrocartilage cytes and it is osteo-chondro progenitor cells with the potential ability to evolve muti-differentiated. This added evidence to the view that condylar cartilage differentiated from osteo-chondro progenitor cells in the mesenchymal cells of mancibular periosteal.

体外分离培养鼠胚下颌体骨膜间质细胞并研究其生物学特性，通过多向诱导实验进一步证实：下颌骨膜间质细胞可能为骨—软骨的前体细胞，可分化为成骨细胞及纤维软骨细胞，具有多向分化潜能，此结果进一步支持髁突软骨是由下颌骨膜间质中骨—软骨前体细胞发育而来。

Results of IHC confirmed that ER located mainly in cytoplasms and nuclei of osteoblast, in addtion to its location in osteocyte and osteoclast, which meets the results of abroad reports.

本研究免疫组化结果证实：雌激素受体定位于成骨细胞的胞浆和胞核。除此之外，骨细胞及破骨细胞中也存在ER。这一结果与国内外研究报道相符。

Atorvastatin may inhibit the proliferation, but stimulate the differentiation of osteoblasts derived from bone marrow stromal dells, accelerate the mineralization of osteoblasts and promote the maturation of bone nodules.

阿托伐他汀可促进骨髓基质细胞来源的成骨细胞的分化，抑制了细胞增殖，促进骨结节钙化。

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。
