Tissue engineering represents an innovative approach for the treatment of severe bone defects in which cells and scaffolds are used for restoring or repairing damage tissues. Adipose-derived stem cells (ASCs) may represent, alone or in association with osteoconductive scaffolds, an efficient approach for bone regeneration. In this study, autologous ASCs were re-implanted in a full-thickness bone defect in the rabbit’s tibia. Animals have been divided in 4 groups: group treated with bio-construct ASCs-hydroxyapatite disk (ASCs-HA), with ASCs or HA alone, and untreated group. Each ASCs population was tested in vitro for evaluate their ability to osteo-differentiate. 8-weeks after surgery, in ASCs-HA treated defects, new bone tissue was observed along the walls and in the inner part of the pores with a mature lamellar conformation and with biomechanical properties similar to the native bone tissue concluding that autologous ASCs-HA construct may be a promising treatment for critical bone defects
