ABSTRACT
Proteoglycans consist of core proteins and one or more covalently-linked glycosaminoglycan chains. They are structurally complex and heterogeneous. Proteoglycans bind to cell surface receptors, cytokines, growth factors and have strong affinity for collagen fibrils. Together with their complex spatial structures and different charge densities, proteoglycans are directly or indirectly involved in biomineralization. The present review focused on the potential mechanisms of proteoglycans-mediated biomineralization. Topics covered include the ability of proteoglycans to influence the proliferation and differentiation of odontoblasts and osteoblasts through complex signaling pathways, as well as regulate the aggregation of collagen fibrils and mineral deposition. The functions of proteoglycans in mineralization regulation and biomimetic properties render them important components in bone tissue engineering. Hence, the integrated impact of proteoglycans on bone formation was also succinctly deliberated. The potential of proteoglycans to function therapeutic targets for relieving the symptoms of ectopic mineralization and mineralization defects was also comprehensively addressed.
