Bone-related regeneration via osteoconduction and osteoinduction

Bone-related regeneration via osteoconduction and osteoinduction describes the fundamental biological mechanisms by which bone tissue heals and integrates with graft materials. Osteoconduction is a passive process where a biocompatible scaffold provides a structural framework for native bone cells to migrate and deposit new matrix (Albrektsson & Johansson, 2001). In contrast, osteoinduction is an active process where signaling molecules, such as bone morphogenetic proteins (BMPs), recruit mesenchymal stem cells and induce their differentiation into osteoblasts (Urist, 1965; NIH, 2023). These processes are critical in orthopedic and dental surgery for treating large bone defects, non-union fractures, and spinal fusions (StatPearls, 2023). While not a single molecular target, these mechanisms are modulated by various biomaterials and growth factors to enhance clinical outcomes in regenerative medicine. Therapeutic interventions often utilize recombinant BMP-2 or demineralized bone matrix to trigger these pathways (PubMed, 2022). Understanding these mechanisms allows for the development of synthetic bone substitutes that mimic the natural healing environment, where clinical success depends on the synergy between the scaffold architecture and biological signals.
