Osteoinduction via release of growth factors

Osteoinduction is the process by which molecular signals (principally certain growth factors) stimulate undifferentiated progenitor cells to differentiate into osteoblasts, leading to new bone formation. This mechanism is central to bone healing and regenerative treatments and is regulated by the release of growth factors such as BMPs and TGF-β. These growth factors activate specific cell surface receptors, initiating intracellular signaling pathways (including SMAD, PI3K/AKT/mTOR) that drive osteogenic differentiation and matrix synthesis. Osteoinductive therapies, including recombinant growth factors and select small molecules, are deployed in bone grafting and tissue engineering, but carry risks such as undesired bone formation and immune response.
