Abstract (original English)
Although differential expression of genes is apparent during the adipogenic/osteogenic differentiation of marrow mesenchymal stem cells (MSCs), it is not known whether this is associated with changes in chromosomal structure. In this study, we used ATAC-sequencing technology to observe variations in chromatin assembly during the early stages of MSC differentiation. This showed significant changes in the number and distribution of chromosome accessibility at different time points of adipogenic/osteogenic differentiation. Sequencing of differential peaks indicated alterations in transcription factor motifs involved in MSC differentiation. Gene Ontology (GO) and pathway analysis indicated that changes in biological function resulted from the alterations in chromatin accessibility. We then integrated ATAC-seq and RNA-seq and found that only a small proportion of the overlapping genes were screened out from ATAC-seq and RNA-seq overlapping. Through GO and pathway analysis of these overlapped genes, we not only observed some known biological functions related to adipogenic/osteogenic differentiation but also noticed some unusual biological clustering during MSC differentiation. In summary, our work not only presents the landscape of chromatin accessibility of MSC during differentiation but also helps to further our understanding of the underlying mechanisms of gene expression in thes
