Abstract
Recent researches about calcium phosphate (CaP) biomaterials used as drug delivery systems are focusing on the better understanding of the microenvironment around the implant-host tissue interface, with the aim to provide a bone response in pathological ones. Towards the improvement of the osteogenic potential of CaP drug carriers, dandelion-like β-SrHPO4 clusters (Φ10-20 μm) has been prepared by a homogeneous precipitation method under the hydrolysis of carbamide. Adhesion, spreading, proliferation, osteogenic differentiation and mRNA expression of bone mesenchymal stem cells (BMSCs) mediated by β-SrHPO4 clusters were investigated. Highly osteoconductive and biodegradable octacalcium phosphate with similar structure was employed as the control. By contrast, β-SrHPO4 clusters exhibited remarkably better affinity, enhanced proliferation and osteogenic differentiation of BMSCs, providing a promising alternative bioactive bone substitute and drug carrier for tissue repair. With the unique dandelion-like microstructure, we believe that our as-prepared material will open up new avenues for applicability of CaP drug delivery systems in the near future.
