We took advantage of a dystrophic mouse model of transient macrophage-depletion, mdxITGAM-DTR mice, in order to analyze the role of macrophage in skeletal muscle regeneration. We generated the transcriptome of satellite cells (SCs) and alpha7Sca1 cells purified by cell sorting from mdxITGAM-DTR mice. The mice were treated, by intramuscular injection, with PBS, as vehicle, or with Diphtheria toxin (DT) in order to achieve the macrophage depletion form hind-limb muscle We described a shift in identity of muscle stem cells dependent on the crosstalk between macrophages and satellite cells. Indeed macrophage depletion determines an exacerbated dystrophic phenotype associated with adipogenic conversion of SCs and reduction of the SC pool.
