Bone marrow mesenchymal stem cells (BMSCs) nowadays are regarded as promising candidates in cell-based therapy for the regeneration of damaged bone tissues that are either incurable or intractable due to the insufficiency of current therapies. Recent studies suggest that BMSCs differentiate into osteoblasts, and that this differentiation is regulated by some specific patterns of epigenetic modifications, such as DNA methylation. However, the potential role of DNA methylation modification in BMSC osteogenic differentiation is unclear. In this study, we performed a genome-wide study of DNA methylation between the noninduced and induced osteogenic differentiation of BMSCs at day 7. We found that the majority of cytosines in a CpG context were methylated in induced BMSCs. Our results also revealed that, along with the induced osteogenic differentiation in BMSCs, the average genomic methylation levels and CpG methylation in transcriptional factor regions (TFs) were increased, the CpG methylation level of various genomic elements was mainly in the medium-high methylation section, and CpG methylation levels in the repeat element had highly methylated levels. The GO analysis of differentially methylated region- (DMR-) associated genes (DMGs) showed that GO terms, including cytoskeletal protein binding (included in Molecular Function GO terms), skeletal development (included in Biological Process GO terms), mesenchymal cell differentiation (included in Biological Process GO terms), and stem cell differentiation (included in Biological Process), were enriched in the hypermethylated DMGs. Then, the KEGG analysis results showed that the WNT pathway, inositol phosphate metabolism pathway, and cocaine addiction pathway were more correlative with the DMRs during the induced osteogenic differentiation in BMSCs. In conclusion, this study revealed the difference of methylated levels during the noninduced and induced osteogenic differentiation of BMSCs and provided useful information for future works to characterize the important function of epigenetic mechanisms on BMSCs’ differentiation.

Abstract Background Bone marrow (BM) and umbilical cord (UC) are the main sources of mesenchymal stem cells (MSCs). These two MSCs display significant differences in many biological characteristics, yet the underlying molecular mechanisms need to be explored. Results In this study, to better understanding the biological features of MSCs, we isolated BMMSCs and UCMSCs from inbred Wuzhishan miniature pigs and generated the first global DNA methylation and gene expression profiles of porcine MSCs. The results showed that the osteogenic and adipogenic differentiation ability of porcine BMMSCs is stronger than that of UCMSCs. Stem cell surface marker CD90 were positively detected in both BMMSCs and UCMSCs. 587 genes were differentially methylated (280 hypermethylated and 307 hypomethylated) at the promoter regions between BMMSCs and UCMSCs. Meanwhile, 1,979 differentially expressed genes (1,407 up-regulated and 572 down-regulated) were identified between BMMSCs and UCMSCs. Integrative analysis reveals that 120 genes displayed differences in both gene expression and promoter methylation. Gene Ontology enrichment analysis revealed that these differential genes were associated with cell differentiation, cell migration, and immunogenicity properties. Remarkably, skeletal system development related genes were significantly hypomethylated and up-regulated in UCMSCs, while cell cycle genes were significantly higher down-regulated and hypermethylated, implying UCMSCs have higher cell proliferative activity and lower osteogenic differentiation potential than BMMSCs. Conclusions Our results indicate that DNA methylation plays an important role in regulating the biological characteristics differences between BMMSCs and UCMSCs. The study might provide a molecular theory basis for the application of porcine MSCs in human.
