    Dissecting Murine Muscle Stem Cell Aging through Regeneration Using Integrative Genomic Analysis

    Scientists used an integrative genomics approach to profile muscle stem cells from young and aged animals before and after injury. Integration of these datasets revealed aging impacts multiple regulatory changes through significant differences in gene expression, metabolic flux, chromatin accessibility, and patterns of transcription factor binding activities.
