Chromatin structure profiling of mouse muscle stem cells by ATAC-seq
By comparing ATAC-seq from freshly isolated satellite cells (QSC), satellite cells isolated 2.5 days post-injury (ASC), and satellite cells cultured for differentiation, we observed a gradual opening of satellite cell chromatin structure during activation and  differentiation process. We used ATAC-seq to study the functional role of LncMyod during satellite cell differentiation and identified genes that exhibited decrease of accessibilities to their transcription start sites (TSS). The majority of the regions are myogenesis-related genes, suggesting LncMyod plays a critical role in establishing permissive chromatin environment for myogenic progression. Overall design: Examination of chromatin accessibility using ATAC-seq in QSC, ASC, satellite cells cultured for differentiation with control siRNA (LncMyod Control), and satellite cells cultured for differentiation with siRNA targeting LncMyod (LncMyod Knockdown).
