Notizen:
Surfaces of sintered hydroxyapatite (HAp) were treated with four kinds of acids,hydrochloric acid (HCl), nitric acid (HNO3), sulfuric acid (H2SO4) and hydrogen peroxide (H2O2). Onthese acid-treated HAp surfaces, osteoblast-like MC3T3-E1 cells were cultured for 20 days. Thematrix mineralization was observed in HCl-treated HAp and HNO3-treated HAp, but not innon-treated HAp, H2SO4-treated HAp and H2O2-treated HAp. Gene expressions of Bglap2 encodingosteocalcin and Akp2 encoding alkaline phosphatase were higher in HCl-treated HAp andHNO3-treated HAp than those in the others. These results indicate that not only hydrochloric acid butalso nitric acid improves performance of HAp to mature osteoblast
