Effection on the potential of growth and mineralization of cultured osteoblasts on ITO glass coated with functional polymer-polypyrrole in vitro / 实用口腔医学杂志

ABSTRACT

Objective: To study the potential of growth and mineralization of cultured osteoblasts on the indium tin oxide conductive(ITO) glass disk coated with polypyrrole film (Ppy) . Methods: Osteoblasts were seeded onto ITO glass or ITO glass coated with polypyrrole film of implant materials. The cells were stained by HE and Von Kossa, observed by light microscope and scanning electron microscope (SEM) on day 3, 7, 14 and 28 after seeding respectively. Results: The osteoblast cells attached well to both ITO surfaces and Ppy films, mineralized nodules was observed on Ppy film. Conclusion: The polypyrrole films have good bone biocompatibility and it can be used as the biomaterials for dental implant.
