It has not been determined the best scaffold-structure for bone engineering. Because of this, we compared Honeycomb porous structure (HPS) and Interconnected porous structure (IPS) with or without KUSA/ A1 cells implanted in mice. The transplants were subjected to radiological and histological examinations after 1,2,4 and 8 weeks of implantation. KUSA/A1 cells alone showed small islands of new bone. Both scaffolds alone did not reveal any bone induction. KUSA/A1-HPS presented the scaffold partially filled with new bone. In contrast, KUSA/A1-IPS showed the whole scaffold filled with new bone. Our results indicated that cotton structure plays an important role in carrying the cells giving the precise size, shape and comfortable environment.
