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.
本研究的目的是表征成骨样细胞在经过不同时长氩等离子体清洗（PC）处理的钛表面上的体外细胞行为。对于经过1分钟等离子体处理的表面，观察到最高水平的细胞附着。表面分析表明，尽管PC处理显著提高了表面润湿性，但处理时间较长时会观察到无机污染物的存在，这可能干扰了细胞附着。建议进一步开展工作，以研究成骨细胞在植入物表面生长时的长期表型表达。
