   本實(shí)驗(yàn)結(jié)果表明：細(xì)胞壁與細(xì)胞膜之間相互作用的變化是煙草細(xì)胞對(duì)甘露醇脅迫處理的原初響應(yīng)。
2. 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
