Epigenetic stress responses induce muscle stem cell aging by Hoxa9 developmental signals [RNA-seq]

Background and Aims: Analysis of aging-induced impairments in satellite cells (SCs) – the stem cells of skeletal muscle that are required for its regeneration. Hox genes are known to control stem cell function and development of various tissues. Overall design: Hindlimb muscles from young adult (3-4 months) and old (22-28 months) C57BL/6J mice were injured by BaCl2 injection in order to induce satellite cell activation. Satellite cells were isolated 3 days after injury and gene expression was analyzed.
