Regeneration of osseous tissue

Regeneration of osseous tissue refers to the biological process by which new bone is formed to replace damaged, lost, or defective bone. This process relies on the coordinated action of multiple cell types—including osteoblasts, osteoclasts, osteocytes, and mesenchymal stem cells—and the activity of signaling molecules such as bone morphogenetic proteins (BMPs), transforming growth factor beta (TGF-β), fibroblast growth factors (FGFs), and others. Molecular pathways like BMP/Smad, Hedgehog, and Wnt play central roles in orchestrating cell differentiation, matrix production, and mineralization. Therapeutic strategies target these pathways to enhance bone healing, often using biomolecules, recombinant proteins, and delivery systems to promote osseous regeneration in conditions such as fractures, bone defects, and degenerative bone diseases. However, the process is complex, with risks of side effects such as ectopic bone formation or inflammation.
