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.
