Article Novel Oxysterols Have Pro-Osteogenic and Anti-Adipogenic Effects In Vitro and Induce Spinal Fusion In Vivo

Histological analysis showed trabecular and cortical bone formation by oxysterols and rhBMP2 within the fusion mass, with robust adipogenesis in BMP2-induced bone and significantly less adipocytes in oxysterol-induced bone. These data suggest that Oxy34 and Oxy49 are effective novel osteoinductive molecules and may be suitable candidates for further development and use in orthopaedic indications requiring local bone formation
