In this study, bioactive hydroxyapatite-based bioceramics starting from cuttlefish bone powders have been prepared and characterized.

Abstract

In this study, bioactive hydroxyapatite-based bioceramics starting from cuttlefish bone powders have been prepared and characterized. In particular, fragmented cuttlefish bone was co-sintered with 30 wt% of Bioglass®-45S5 to synthesize hydroxyapatite-based powders with enhanced mechanical properties and bioactivity. Commercial synthetic hydroxyapatite was treated following the same procedure and used as a reference. The structure and composition of the bioceramics formulations were characterized using Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. After the thermal treatment of cuttlefish bone powder added with 30% wt. Bioglass®, new phases with compositions of sodium calcium phosphate (Na3 Ca6 (PO4 )5 ), β-tricalcium phosphate (β-TCP, Ca3 (PO4 )) and amorphous silica were detected. In vitro cell culture studies were performed by evaluating proliferation, metabolic activity and differentiation of human osteoblast-like cells (MG63). Scaffolds made with cuttlefish bone powder exhibited increased apatite deposition, ALP activity and cell proliferation compared to commercial synthetic hydroxyapatite. In addition, the ceramic compositions obtained after the combination with Bioglass® further enhanced the metabolic activity of MG63 cell and promoted the formation of a well-developed apatite layer after 7 days of incubation in DMEM.
