Abstract:

BACKGROUND: Type I collagen is the main component of the extracellular matrix of bone tissue. Numerous studies have shown that it has the ability to induce osteogenic differentiation, and plays an important role in the process of bone mineralization. Currently, bionic materials are being developed as an alternative to type I collagen in the field of biological materials.
OBJECTIVE: To review the mechanism of osteogenesis induced by type I collagen, the role of type I collagen in the biomineralization process, and the real-time expression of type I collagen during distraction osteogenesis.
METHODS: With the key words of “type I collagen, bone marrow mesenchymal stem cells, osteoblast, distraction osteogenesis, mineralization” in Chinese and English, we performed a computer-based search in CNKI and PubMed database for relevant articles published from 1990 to 2017. Finally, 58 eligible articles were included in result analysis.
RESULTS AND CONCLUSION: Type I collagen induces osteogenic differentiation of bone marrow mesenchymal stem cells and osteoblasts mainly through collagen-integrin signaling pathways. In the early stage of distraction osteogenesis, type I collagen is less secreted, but the secretion increases in the middle and later stages, eventually becoming the main component of extracellular matrix. There are two mainstream theories of mineralization mechanisms: (1) Type I collagen plays a role as a template scaffold in biomineralization, guiding the deposition and mineralization of calcium. (2) Amorphous calcium phosphate infiltrates between collagen fibers and changes from amorphous to crystalline state, forming an aligned crystal structure.
