Bone regeneration induced by adenoviral vectors carryingtil-1/Cbfa1 genes implanted with biodegradable porous materials in animal models of osteonecrosis of the femoral head

A new approach for bone regeneration is needed for idiopathic osteonecrosis of the femoral head (ION). Core binding factor alpha1 (Cbfa1) was reported in 1997 as the most important transcription factor for osteoblastic differentiation. The transgenics of transcription factors affecting bone formation might be useful tools for the bone regeneration. The purpose of this study was to investigate the effects of the implantation of adenoviral vectors...
