Growing evidence indicates that biomaterials that contain bioactive glass (BG) exert positive
effects on bone tissue repair. Strontium-substituted BGs have been demonstrated to promote
bone formation while inhibiting bone resorption by osteoclasts. In this study, we fabricated
composites containing gelatin combined with different concentrations of strontium (Sr)-
delivering glasses. We then investigated the in vitro effect of the presence of Sr in the
polymer matrix on proliferation and differentiation of bone marrow mesenchymal stem cells …
