Bone regeneration is the biological process by which bone tissue restores its structure and function following injury, remodeling, or pathological loss. It involves a tightly regulated sequence of events including inflammation, recruitment and differentiation of mesenchymal stem cells into osteoblasts and chondrocytes, endochondral and/or intramembranous ossification, and coupled activity of osteoclasts and osteoblasts for remodeling. Key molecular pathways include BMP/TGF-β, Wnt/β-catenin, VEGF-driven angiogenesis, and RANK/RANKL/OPG signaling. Bone regeneration is modulated by mechanical loading, local vascularization, immune–bone cell interactions, and systemic endocrine factors, enabling restoration of biomechanical integrity and mineral homeostasis.
For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But ...
