Collagen is widely used in biomedical applications, e.g., tissue growth, wound dressings. This study is focused on the effects of the conformation of collagen and glycosaminoglycan on osteoblast adhesion, growth, morphology and functions. We found that soluble collagen is better than fibrillar collagen and denatured collagen on cell growth and alkaline phosphatase activity. Furthermore, we found that when collagen was coated on a surface with heparin, cell adhesion was best when heparin concentration was 0.02 mg/ml.application/pdf803868 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所骨母細胞膠原蛋白肝素蛋白質形態細胞貼附仿生奈米化之生醫材料表面對於骨母細胞的行為之影響評估reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9426/1/932214E002035.pdf
