Cell adhesion to surface of the substrate is essential to development of the anchorage - dependent cells. only after adhering to surface followed by spreading can cells develop and proliferate. most synthetic polymers used as orthopaedic matrix substitute present hydrophobicity, which may correlates to the low degree of cell attachment. modification with cell adhesion protein / peptides can be benificial to the cell adhesion on polymers and then affect the cell proliferation and differentiation. cell attachment to substrate is primarily mediated by integrins, a widely expressed family of heterodimeric surface receptors. most extrcellular matrix proteins such as fibronectin, osteopontin, collagen type i, bone sialoprotein and vitronectin contain an arg - gly - asp ( rgd ) sequence which is specific to the fixation of cell membrane receptors like integrin. the main aim of this research is to measure, assess adhesion, proliferation of rabbit marrow stromal cells ( mscs ) on the polymers coated by fibronectin, collagen type i or biotie gen, which includes : ( 1 ) biologic characteristics of rabbit mscs were observed by two types of separating method in primary culture. ( 2 ) adhesion, proliferation and differentiation of mscs cultured on polymers coated with biotiegen were assessed. ( 3 ) also, adhesion, proliferation and differentiation of mscs were assessed on plga film or porous plga substrates coated with fibronectin, or collagen type i respectively. ( 4 ) bone formation was observed on the porous plga substrates coated with collagen type i in vivo. this research aims to give new way to make novel synthetic bone with cell adhesion and high bone induction capabilities

Friction - reduction mechanism of dlc gradient film could be attributed to its smooth and hard amorphous structure. the hemocompatibility of dlc gradient film had been evaluated by investigating platelet consumption ratio, blood protein adsorption and platelet adhension and morphology on surface of materials
Dlc梯度薄膜材料與ti6a14v合金材料的血小板消耗率相差不大，但是dlc梯度薄膜材料對血漿蛋白的吸附明顯低於ti6a14v合金材料，可以預料血小板在dlc梯度薄膜材料表面粘附也會較少。 -
