Fabrication of Biomimetic PCL Scaffold Using Rapid Prototyping for Bone Tissue Engineering
E-mail:
We report the fabrication of a porous three-dimensional (3D) scaffold using a 3D plotting system, with applications in bone tissue engineering. Biomimetic surface coatings of hydroxyapatite were formed using concentrated simulated body fluid (SBF). The mineralized scaffold had a uniform interconnected porous structure. The apatite that was formed on the surface of the scaffold was characterized by using energy dispersive spectroscopy (EDS), Xray powder diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The biological properties of the scaffold were evaluated using WST-1 assays of alkaline phosphatase (ALP) activity and gene expression of D1 mouse mesenchymal stem cells. The results show that the biomimetic scaffolds exhibited good apatite-forming properties, with favorable cell proliferation and differentiation for bone formation. Therefore, these biomimetic scaffolds with hydroxyapatite coatings have potential applications in bone regeneration.
