摘要
Several investigations have demonstrated a precise balance to exist between bone morphogenetic protein (BMP) agonists and antagonists, dictating BMP signaling and osteogenesis. Using RNA interference, we have previously reported that reduction of noggin enhanced BMP signaling and in vitro osteoblast bone formation. This study examined the in vivo biology of noggin-suppressed osteoblasts, in the setting of critical-sized defects in mice. Radiographic and histological analyses were employed to evaluate differences in bone regeneration across the region of injury.
