报告摘要:The impact of bone diseases and trauma in the whole world has increased significantly in the past decades. Bioactive glasses are regarded as an important bone regeneration material due to their generally excellent osteoconductivity and osteostimulativity. A new class of bioactive glass, referred to as mesoporous bioglass (MBG), was developed seven years ago, which has highly ordered mesoporous channel structure and high specific surface area. The aim of study is (1) to investigate the in vitro and in vivo bone-formation ability of novel class of MBG; (2) to investigate the potential application of MBG for drug/growth factor delivery and bone tissue engineering. Our study has found that MBGs offer a suite of features which are important for efficient drug delivery and bone regeneration. The typical features include that: (1) they possess well ordered mesoporous channel structure and controllable nanopore size, which endows them high specific surface area and pore volume. The improved physical properties play an important role to enhance their biological behavior; (2) they have excellent in vitro and in vivo bioactivity. Particularly, they have shown the stimulatory effect to enhance in vivo bone formation, compared to non-mesoporous bioglass; and (3) they are excellent carriers for the delivery of drugs and growth factors to further improve anti-bacteria ability and stimulate the growth and differentiation of tissue cells as well as bone tissue formation.
