Abstract (original English)
In this study, we report an industrial-scale fabrication method of a multifunctional polymer composite as a scaffold material for bone tissue engineering. This study successfully demonstrated the potential of applying industrial polymer processing technologies to produce specially functionalized tissue engineering scaffolds. With the inclusion of a newly synthesized multifunctional additive, silver-doped-calcium phosphate (silver-CaP), the composite material exhibited excellent osteogenic inducibility of human adipose-derived stem cells (hASC) and satisfactory antibacterial efficacy against Escherichia coli and Staphylococcus aureus. Also, relative to previously reported methods of direct loading silver particles into polymeric materials, our composite exhibited significantly reduced silver associated cytotoxicity. The enhanced biocompatibility could be a significant advantage for materials to be used for regenerative medicine applications where clinical safety is a major consideration. The impact of different silver loading methodologies on hASC' osteogenic differentiation was also studied. Overall, the results of this study indicate a promising alternative approach to produce multifunctional scaffolds at industrial-scale with higher throughput, lower cost, and enhanced reproducibility. © 2018 Wiley Periodicals, Inc.
