Abstract: BACKGROUND: At present, a single biological scaffold material is difficult to meet the osteogenic needs of bone tissue engineering, and bone marrow mesenchymal stem cells have excellent osteogenic characteristics. Composite scaffolds and scaffolds combined with growth factors have better osteogenic ability. It is a research hotspot at present.
OBJECTIVE: To review different biological scaffolds and their modified scaffolds to promote the osteogenic differentiation of bone marrow mesenchymal stem cells.
METHODS: The related articles published in CNKI, Wanfang, VIP, PubMed and Embase databases from January 2014 to July 2020 were searched by the first author with the keywords of “bone marrow mesenchymal stem cells, scaffolds, osteogenic differentiation, hydroxyapatite, collagen, chitosan” in English and Chinese. Finally, 69 articles were selected. 
RESULTS AND CONCLUSION: The rapid development of bone tissue engineering can effectively solve the problem of bone defect repair. Seed cells and biological scaffold materials are the core of bone tissue engineering. Bone marrow mesenchymal stem cells have excellent osteogenic differentiation ability and are widely used in bone tissue engineering. The combination of different scaffold materials, the use of advanced preparation technology, or the surface modification of scaffolds and the addition of growth factors can fully combine the advantages of various biological scaffold materials, induce the osteogenic differentiation of bone marrow mesenchymal stem cells and the formation of scaffold blood vessels, and achieve the purpose of repairing bone defects, and is the research focus of bone tissue engineering.
