Abstract:

BACKGROUND: Demineralized bone matrix as bone tissue engineering biological scaffold material is more researched currently, which has osteoinductive and osteoconductive.
OBTECTIVE: To summarize the development of demineralized bone matrix as bone tissue engineering scaffold material and to prospect its trend.
METHODS: The relative literatures addressing demineralized bone matrix as bone tissue engineering scaffold material published between January 1965 and May 2013 in PubMed database, Chinese Biomedical Database, Wanfang Database and FMJS database were searched by the first author. The key words were “demineralized bone matrix, scaffold material, growth factor, cells, drugs” in English and Chinese. According to the inclusion criteria, repetitive researches were excluded, and finally 34 articles were included.
RESULTS AND CONCLUSION: Scaffold material is the key composition of tissue engineered bone, and only demineralized bone matrix has both osteoinductive and osteoconductive properties which cannot only provide space for bone repair, but also can be combined with bioactive factors, living cells, antibiotics in vitro to construct bone graft thereby promoting healing of bone defects. However, this technique is also facing some problems to be solved such as the ratio of demineralized bone matrix and various substances, disinfection, preservation of osteogenetic activity and antigenicity elimination. Sufficiently understanding demineralized bone matrix as bone tissue engineering scaffold can provide a theoretical basis for its clinical service.
