Growth factors are a group of proteins that play a crucial role in regulating cellular processes, including proliferation, differentiation, and survival. There is significant scientific evidence supporting the use of certain growth factors in bone health and repair, particularly in the context of skeletal system support. For example, bone morphogenetic proteins (BMPs), a subgroup of the transforming growth factor-beta (TGF-β) superfamily, have been extensively studied for their ability to induce bone formation. BMPs are used clinically in orthopedic and dental applications to enhance bone healing and regeneration, especially in cases of fractures, spinal fusions, and bone defects. Other growth factors, such as platelet-derived growth factor (PDGF) and insulin-like growth factors (IGFs), also contribute to bone remodeling and repair by stimulating the proliferation and differentiation of osteoblasts (bone-forming cells) and supporting angiogenesis (formation of new blood vessels). The use of recombinant growth factors in bone grafts and tissue engineering is supported by a substantial body of preclinical and clinical research, although their application is often limited to specific medical settings due to cost and potential side effects. Overall, the use of growth factors to support the skeletal system is scientifically validated, especially in targeted therapeutic situations rather than as general dietary supplements.
