本研究的目的是表征成骨细胞样细胞在钛表面制备的氩等离子体清洁（PC）处理不同的时间长度的体外细胞行为。最高水平的细胞附着的表面已被等离子体处理一分钟。表面分析表明，虽然PC处理显着改善表面润湿性，无机污染物的存在下观察到较长的处理时间，并可能干扰细胞附着。建议进一步研究成骨细胞在植入物表面生长时的长期表型表达。
The purpose of this research was to characterize the in vitro cellular behavior of osteoblast-like cells on titanium surfaces prepared with argon plasma-cleaning (PC) treatments for various lengths of time. The highest levels of cell attachment were observed for surfaces which had been plasma-treated for one min. Surface analyses indicated that although PC treatments dramatically improved surface wettability, the presence of inorganic contaminants was observed with longer treatment times and may have interfered with cell attachment. Further work is suggested to investigate the longer-term phenotypic expression of osteoblasts when grown on implant surfaces.
