PDGF can modulate the functional balance between OB and OC directely or obliquely, and promote bone fracture healing and bone defect repairs, which is considered as a unwounded method that replaces some operations to treat such kind of patients.

PDGF直接或通过与其他生长因子的协同作用，调节成骨-破骨细胞之间的功能性平衡，加快骨折愈合和其他骨病损伤修复。如能实现和骨生物材料有机结合，有望使无创治疗代替有创手术，从而使此类患者减轻痛苦，缩短疗程。

The result indicated that PLA is a material able to be used as a carrier of BMP in inducing osteogenesis, it has a better effect of inducing osteogenesis than xenogenous cancellous bone matrix.

结论PLA可以作为BMP的载体修复骨缺损，它比异种松质骨基质载体的成骨效果更理想。

Results Positive staining for VEGF was distributed mostly in osteoblasts, osteoclasts and newly-born osteocytes. Vascular endothelial cells and bone marrow cells also showed VEGF positive reaction. Hypertrophic chondrocytes in calcifying region of chondroephysis were VEGF positive, but VEGF was absent from chondrocytes in other zones of chondroephysis.

结果 VEGF阳性反应主要见于成骨细胞、破骨细胞及新生骨细胞中，血管内皮细胞及骨髓细胞也呈阳性反应；骺软骨钙化区肥大的软骨细胞为VEGF阳性反应，但其它区域的软骨细胞中无VEGF表达。

Methods Porous heterogenous deproteinication boneof pig obtained by physiochemical process and osteoblast acquired from the cranical bone of fetal rabbits were cultured 10 days in vitro and explanted into the left side of dorsa muscle of 30 adult rabbits.

将经过物理化学方法处理制得的冻干猪脱蛋白型松质骨与胎兔颅骨来源的成骨细胞体外培养 10d后，在无菌条件下植入 3 0只成年新西兰兔背部肌肉内，对照组为同体单纯植入猪脱蛋白型松质骨。

The inhabiting effects of steteching at 1500μεwere more significant than that of 1000με.

拉伸对成骨细胞生理活性的影响随加载时间的增加而增加。

METHODS: The osteoblasts from cranial bones of 5-day-old Wistar mice were seeded and passaged.

用出生5d的Wistar品系小鼠的颅骨接种成骨细胞并传代。

BMSCs cultured in vitro contain osteogenic precursor cells, and the passaged cells possess osteogenic potential.

体外分离培养的BMSCs中含有骨源性前体细胞，传代细胞具有较强的成骨潜能。

The expression of ZUB1 antigen had no difference after passaging,but it was significant decreased after differentiated into adipocytes and osteocytes,which indicated that the ZUB1 antigen may be an important marker of "stem" and was associated with the differentiation of MSCs.

当诱导骨髓MSCs向成骨细胞和脂肪细胞定向分化时，流式细胞检测显示ZUB1抗原表达相应减弱，提示ZUB1抗原可作为MSCs干细胞特征的标志分子，且可能参与了MSCs分化的细胞活动。

RANK ligand has been shown in preious studies to be an important inflammatory protein that can lead to bone loss through actiation of bone resorbing cells.

而这个RANK配基在目前的研究中被认为是有一个重要的炎症蛋白质，它会激活骨吸收细胞而造成骨丢失。

Results The sandblasting and the SLA surface showed a significant different to smooth surface in the proliferation osteoblasts.

结论喷砂并酸蚀处理的新型钛合金在体外实验表现为不同程度的促进成骨细胞增殖及功能活性表达。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
