Project description:Bone development and repair depends on the differentiation of mesenchymal stem cells (MSCs) into osteoblasts. MSCs can be differentiated towards osteoblasts in vitro, making these cells a convenient tool for investigation of osteogenesis. Molecular characterization of this process is relevant for the application of MSCs in skeletal regenerative medicine, and for understanding the deregulation of osteogenesis in bone disease. Cellular differentiation is driven by highly regulated changes in gene expression, which at the level of transcription is associated with DNA binding of transcriptional regulators and local changes in chromatin landscape. By sequencing of RNA (RNA-Seq) and immunoprecipitated chromatin (ChIP-Seq) we have characterized gene expression, histone modification changes and DNA binding of the bone master regulator RUNX2 in osteogenic differentiation. Data from the RNA-Seq experiment has also been deposited at ArrayExpress under accession number E-MTAB-1829 (https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-1829/).

Project description:We performed multiomic high-throughput sequencing to recapitulated the primary mechanism of mesenchymal stem cells osteogenesis. We analysed the H3K27ac ChIP-seq and RNA-seq data before and after osteogenesis, and identified super enhancers (SEs) regulated osteogenic identity genes in MSCs.
