Unlike other drugs used in osteoporosis therapy, strontium shows a dual effect on bone metabolism by attenuating cellular resorption and simultaneously enhancing new bone tissue formation. Current concerns regarding the systemic application of highly dosed strontium ranelate led to the development of strontium\u2010modified scaffolds based on mineralized collagen (MCM) capable to release biologically active Sr<jats:sup>2+<\/jats:sup> ions directly at the fracture site. In this study, we investigated the regenerative potential of these scaffolds. For <jats:italic>in vitro<\/jats:italic> investigations, human mesenchymal stromal cells were cultivated on the scaffolds for 21\u2009days (w\/ and w\/o osteogenic supplements). Biochemical analysis revealed a significant promoting effect on proliferation rate and osteogenic differentiation on strontium\u2010modified scaffolds. <jats:italic>In vivo,<\/jats:italic> scaffolds were implanted in a murine segmental bone defect model\u2014partly additionally functionalized with the osteogenic growth factor bone morphogenetic protein 2 (BMP\u20102). After 6 weeks, bridging calluses were obtained in BMP\u20102 functionalized scaffolds; the quality of the newly formed bone tissue by means of morphological scores was clearly enhanced in strontium\u2010modified scaffolds. Histological analysis revealed increased numbers of osteoblasts and blood vessels, decreased numbers of osteoclasts, and significantly enhanced mechanical properties. These results indicate that the combined release of Sr<jats:sup>2+<\/jats:sup> ions and BMP\u20102 from the biomimetic scaffolds is a promising strategy to enhance bone regeneration, especially in patients suffering from osteoporosis. \u00a9 2019 Wiley Periodicals, Inc.
