Abstract: | The use of synthetic materials for biomedical applications still presents issues owing to the potential for unfavourable safety characteristics. Currently, there is increasing interest in using natural, marine-derived raw materials for bone tissue engineering. In our study, the endoskeleton of the mollusc Sepia, i.e. cuttlebone (CB), was used with regenerated cellulose (RC) to prepare three-dimensional composite bone grafts. CB microparticles were mechanically immobilised within a cellulose gel, resulting in a macroporous structure upon lyophilisation. The interconnected porous structure of the regenerated cellulose/cuttlebone (RC/CB) composite was evaluated by micro-computed tomography. The porosity of the composite was 80%, and the pore size predominantly ranged from 200 to 500 μm. The addition of CB microparticles increased the specific scaffold surface by almost threefold and was found to be approximately 40 mm?1. The modulus of elasticity and compressive strength of the RC/CB composite were 4.0?±?0.6 and 22.0?±?0.9 MPa, respectively. The biocompatibility of the prepared RC/CB composite with rat hepatocytes and extensor digitorum longus muscle tissue was evaluated. The obtained data demonstrated that both the composite and cellulose matrix samples were non-cytotoxic and had no damaging effects. These results indicate that this RC/CB composite is a novel material suitable for bone tissue-engineering applications. |
