Ore-binding factor alpha 1 plays an essential role in bone formation and osteoblast differentiation and serves as a master gene regulating osteoblast-specific gene expression. The gene is expressed in cells of the osteoblast lineage only, and when expressed in non-skeletal cells, the cells assume many of the characteristics of an osteoblast.

The authers fetched the embryo calvarial peristeum tissue, got human osteoblast by enzyme-assimilating methods and tissue-block culture methods. We observed the morphological change, growth feature and osteogentic capability, of osteoblast during culture in vitro with phase contrast invert microscope, drew the growth curre and identified the cells by alkaline phosphatase dye. At same time, the morphology and bioactivity of 3-5th-generation osbeoblast and anabiotic cells was studied comparatively. 2. titanium particles were examined by scanning electron and the size was determined by semi-automated image analysis. The 3-5 th gereration of human osteoblast were cultured in medium with different concentration of particulates titanium alloy (1mg/ml, 0.1mg/ml, 0.01mg/ml). Cell growth and proliferation was detected by MTT method after 2、4、6 days that particles were added into medium and ALP activity was measured by kit after 4、7、10 days respectively. 3. With above same methods,the 3-5th generation of human osteoblasts were cultured for 3、6、9days after different concentration of particulates titanium alloy (1mg/ml, 0.1mg/ml, 0.01mg/ml) were added into the medium and OPG gene expression was quantified by RT-PCR.

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:(1) CBC possesses a natural trabecular structure. Its components is similar to the mineral of bone.(2) CBC has great cellur biocompatibility. It can promote cell adhesion, proliferation and secretory while needn t modification.(3) In nude mice, the ectopic osteogenesis of MCCAB was obvious which was better than that of CBC alone and the new bone formation increased in pace with time. In the MCCAB, both intramembranous and cartilaginous osteogeneses were seen but the former dominated.(4) When MCCAB was autotransplanted intramuscularly, the osteogenesis was much better than that of negative control groups.(5) The MCCAB can repair autogenous calvaria defects effectively and the effect was much better than that of CBM alone and blank group. Conclusion:(1) CBC possesses good biocompatibility, osteoconduction and porous structure, can be used as scaffold material for constructing of tissue engineering bone.
