成骨细胞的

Although underlying mechanisms ⑴ hae not been elucidated, eidence points to the participation of the nitric oxide and cyclic guanosine 3',5'-monophosphate system.

虽然根本的机制还没有阐明，但是证据显示一氧化氮和环鸟苷酸系统参与其中。这里，我们检测到在MC3T3-E1成骨细胞的分化中基质金属蛋白酶13的mRNA，蛋白和活性的升高，诱生一氧化氮合酶和一氧化氮产物的升高。

B The micropipette aspiration technique was used to study the effects of cyclic stretching on the mechanical property of rat calvirial osteoblasts which were loaded at 500με, 1000μεand 1500μεrespectively with the frequency of 0.4Hz.

利用微管吸吮技术研究应变分别为500με、1000με和1500με，频率为0.4Hz的周期性拉伸刺激对大鼠颅盖骨中分离出的成骨细胞的力学特性的影响。

Some genes'expression has proved to play a significant role in osteogenesis.

成骨细胞的某些基因的表达对骨代谢具有十分重要的意义。

NCPs play a important role in differentiation of osteoblast, formation, calcification, and resorption of bone matrix.

NCPs在成骨细胞的分化、骨基质的形成、矿化和吸收方面均起着重要的作用。

The results showed that:a Cyclic strtching at 500με,1000μεand 1500μεwith the frequency of 0.4Hz affected the physiological activity of osteoblasts delivered from rat calvaria.

应变分别为500με、1000με和1500με，频率为0.4Hz的周期性拉伸刺激影响大鼠颅盖骨中分离出的成骨细胞的生理活性。

The cells in the cambial layer of the periostlum showed low or negative signal in the immediate injury response period. The osteoblasts differentiated from the periosteum cells stained strongly in the intramembranous ossification period, and the differentiated chondrocytes stained most strongly in the chondrogenesis period.

结果 在急性损伤反应期，血肿延伸范围内的骨膜内层细胞有少量表达；在膜内成骨期，成骨细胞表达量较高，骨膜细胞表达量少；在软骨形成期，成熟软骨细胞表达量最高；在软骨内成骨期，肥大软骨细胞不表达，成骨细胞表达量较高。

Results:The effect of P18 on effect on the proliferation on osteoblastic cell depends on the condition of cell culture.

P18对于成骨细胞的作用与TGF-β类似，由于其还具有HA结合活性，在HA骨修复材料的改进以及种植体涂层修饰方面有着广阔的应用前景。

BACKGROUND: Osteoblast allograft has been considered as an ideal wayto enhance the rehabilitation of porotic bone due to its particular property.

背景：成骨细胞的同种异体移植，因其独特的优点，被认为是解决衰老骨重建修复较为理想的方法。

Breast cancer commonly metastasizes to bones, producing both osteolytic and osteoblastic deposits. Different markers for quantitative determination of bone turnover have been developed to evaluate bone metastases of breast cancer. The urinary deoxypyridionline, a crosslink product of collagen molecules found in bone and excreted in urine during bone degradation, and bone specific alkaline phosphatase, an isoenzyme localized in the membrane of osteoblasts and released in circulation during bone formation, were recently described as a group of markers of bone turnover in metastatic cancer.

乳癌患者常见骨髓转移造成溶骨性及成骨性沈积物，而利用不同标记来定量骨质转换形态，可以评估乳癌骨骼转移的变化，而尿液中Deoxypyridinoline是骨质内胶原分子在骨骼破坏分解时至尿中的产物，骨特殊碱性磷酸酵素是一种同形酵素，位於成骨细胞的外膜且在骨骼形成时释放至血液中，利用此两种生化标记，可以来预测乳癌转移至骨骼的转换情形。

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。

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。
