| Research Abstract |
A novel nano-surfaced titanium has been generated by irradiated with Femto-sec laser and demonstrate stimulation of proliferation and differentiation of rat bone stroma cells. Numbers of cultured cell were counted and expressions of collagen and osteocalcin were studied in vitro. The surface roughness was increased by laser irradiation. In the culture with nano-surfaced Ti, the numbers of cultured were increased than those of machined surface at 7 day and at 10 day after the culture. The number of osteocalcin-positive cell increased than that of collagen-positive cell by the immunohistochemistry at 10 day after the culture.
