E-I Representative images of TA muscle sections of 10 weeks old mice stained for PAX7 (green) and EdU incorporation (red). MuSCs without (green arrows) and with EdU-labeling (red arrows) are indicated. (E, F) Deletion of linc-MYH results in increased numbers of muscle stem cells and pronounced increase of the ratio of EdU-positive MuSCs. (G-I) The increase in both the number of MuSCs and EdU positive MuSCs in linc-MYH mutant muscle is abolished by constitutive (G: Pax7-Crepos / INO80-/-, Ino80 KO; H: linc-MYH-/- / Pax7-Crepos / INO80-/-, dKO) and induced (I: linc-MYH-/- / Pax7-CreERT2pos / INO80-/-, dKO CreERT) deletion of INO80 in Pax7 expressing cells.
