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.
