RESULTS: The relative levels of COX2 mRNA as well as the contents of PGE2 and cAMP were elevated after fracture, and were significantly higher in study group than those in control group at 3 and 4 weeks postoperatively. Histological observation revealed that the mineralization of cartilage matrix, the endochondral bone formation and the callus remodelling took place earlier in study group.

结果：环氧化酶2(COX2) mRNA的表达量以及PGE2和cAMP的含量均较骨折前显著上升，且实验组在术后3~4 wk时以上指标明显高于对照组，组织学结果则显示实验组骨折间隙内软骨内成骨和编织骨向板层骨的改建均领先于对照组。

CD34 hematopoietic stem/progenitor cells reside in the bone marrow in close proximity to the endosteal bone surface, surrounded by osteoblasts, stromal cells, and various extracellular matrix molecules. We used a bioartificial matrix of fibrillar collagen I, the major matrix component of bone, as a scaffold for ex vivo expansion of HSCs.

All the muscles rebuilt to stable structure after accomplish of distraction, which may help the post-operative stability.2. The changes of myosin heavy-chain mRNA in muscles of mastication during distraction osteogenesis of mandible in canineThe mRNA of MHCI, MHCH and GAPDH in masseter and geniohyoid were measured by RT-PCR.

试验二犬下颌骨牵张成骨过程中咀嚼肌肌球蛋白重链亚型mRNA含量的变化将所取标本应用RT－PCR对嚼肌与颌舌骨肌肌球蛋白重链的两个亚型，即MHCI与MHCll与内参照GAPDH的InRNA进行半定量检测并进行统计学分析。

Results The results indicated that the cultured human alveolar bone origin cells from 3 patients could successfully express the osteoblasts phenotype in single layered culturing after stimulated by β-glycerophosphate and Dexamethasone.

结果自3人下颌齿槽骨分离培养的齿槽骨细胞在加入β-磷酸甘油和地塞米松刺激的体外培养条件下，均可成功表达成骨细胞的表现型，与同源成纤维细胞相比，差异有显著性(P.05)。

The present invention can make osteoplast and hemopoietic stem cell well grow to result in cell proliferation of 23 times and 49 times separately in 10 days, and is suitable for large scale culture of cells.

本发明的效果和益处是可使成骨细胞及造血干细胞在此系统中良好生长，十天后细胞的扩增倍数分别可达到二十三倍和四十九倍，适合细胞的大规模培养。

Methods The imaging features of nine patients who refused amputation and chose to be treated with Chinese herbal medicine were observed. Of the patients, four were confirmed pathologically, two were found to have pulmonary metastasis at diagnosis, one of femur osteo-genic osteosarcoma with osteogenic metastasis was found in the epiphysis of the homolateral tibia, and the other two were proved to have no possibility of other diseases by radiological specialists to demonstrate the imaging diagnosis of osteosarcoma.

观察拒绝截肢采用中药治愈的9例骨肉瘤影像学表现，其中4例经活检病理证实，2例诊断骨肉瘤时肺部已发现转移，1例股骨成骨型骨肉瘤同侧胫骨骨骺内有成骨性转移，另外2例经影像学专家按举证倒置程序，论证骨肉瘤的影像学诊断，排除了其他病变的可能。

But in maxillofacial bones, it only has about 20 years clinical and experimental study.

Mesenchymal stem cells are multipotent cells derived from many adult tissues, which can differentiate into cells of the mesodermal lineage, such as adipocyte, osteocyte and chondrocyte, as well as cells of other embryonic lineages. They are a promising tool for tissue engineering.

间充质干细胞是一类可从多类成体组织中分离的能向脂肪细胞、成骨细胞和软骨细胞等分化的成体干细胞，是组织工程细胞的一个理想来源。

Raman microspectroscopy was applied to monitor hydroxyapatite associated with the differentiation of the human mesenchymal stem cells to osteoblast.

在人体间叶干细胞分化成骨母细胞时，可利用拉曼光谱仪，对不同时期的骨母细胞做监测；最主要的差异是氢氧基磷灰石(Hydroxyapatite， HA)强度的表现。
