Repairing the Osteochondral Defect in Goat with the Tissue-Engineered Osteochondral Graft Preconstructed in a Double-Chamber Stirring Bioreactor
To investigate the reparative efficacy of tissue-engineered osteochondral (TEO) graft for repairing the osteochondral defect in goat, we designed a double-chamber stirring bioreactor to construct the bone and cartilage composites simultaneously in one β-TCP scaffold and observed the reparative effect in vivo. The osteochondral defects were created in goats and all the animals were divided into ...
متن کاملTissue-engineered composites for the repair of large osteochondral defects.
OBJECTIVE To test the hypothesis that engineered cartilage can provide a mechanically functional template capable of undergoing orderly remodeling during the repair of large osteochondral defects in adult rabbits, as assessed by quantitative structural and functional methods. METHODS Engineered cartilage generated in vitro from chondrocytes cultured on a biodegradable scaffold was sutured to ...
متن کاملPoly-N-Acetyl Glucosamine-SO4 for Repairing Osteochondral Defect in Rabbits
Repair of osteochondral defects created in rabbit femoral trochlea were studied using a water-soluble sulfated p-GlcNAc formulation, (Marine Polymer Technologies, Danvers, MA, USA). After 12 weeks of healing empty defects were compared to defects filled with sulfated p-GlcNAc sponge alone and sulfated p-GlcNAc sponge seeded with autologous chondrocytes. The chondrocyte seeded sponge provided th...
متن کاملBilayered chitosan-based scaffolds for osteochondral tissue engineering: influence of hydroxyapatite on in vitro cytotoxicity and dynamic bioactivity studies in a specific double-chamber bioreactor.
Osteochondral tissue engineering presents a current research challenge due to the necessity of combining both bone and cartilage tissue engineering principles. In the present study, bilayered chitosan-based scaffolds are developed based on the optimization of both polymeric and composite scaffolds. A particle aggregation methodology is proposed in order to achieve an improved integrative bone-c...
متن کاملThe effect of the small and unstable autologous osteochondral graft on repairing the full-thickness large articular cartilage defect in a rabbit model.
We have investigated the effect of the insufficient autologous osteochondral graft on healing of the large articular cartilage defect using a rabbit model. An osteochondral defect, 7 mm in diameter, was made on the patellar groove of the femoral condyle and repaired with two surgical procedures: Group I, the osteochondral fragment as half as the defect was grafted. The graft was unstable and th...
