Abstract: BACKGROUND: N-6 methyladenosine is one of the most common and abundant RNA modifications in eukaryotic mRNA. It modifies the base sites on gene fragments through methylation, affecting the biological functions of RNA such as translation, splicing, expression and degradation. Bone marrow mesenchymal stem cells, a kind of non-hematopoietic stem cells, have potential of multidirectional differentiation and show great application prospects in various bone-related diseases.
OBJECTIVE: To summarize the functions and related mechanisms of various m6A modifying enzymes in osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cells, and to briefly introduce the research methods and prospects of N-6 methyladenosine, so as to provide important reference for gene targeted therapy of bone metabolism-related diseases.
METHODS: By searching several domestic and foreign literature databases, such as PubMed, Web of Science and CNKI. The key words were “m6A, bone marrow mesenchyml stem cell” both in English and Chinese. Finally, 46 articles were included for review. 
RESULTS AND CONCLUSION: The occurrence of N-6 methyladenosine modification is mainly regulated by methyltransferase complex, demethylase and N-6 methyladenosine-specific protease. N-6 methyladenosine modifiers can affect the biological characteristics and functions of bone marrow mesenchymal stem cells at the gene level. There is a regulatory relationship between N-6 methyladenosine and signal transduction pathways related to osteogenic and adipogenic of bone marrow mesenchymal stem cells. N-6 methyladenosine has great potential in the field of bone marrow mesenchymal stem cells related regenerative medicine.
