Muscle biopsies taken from 30 up to 180 days after ablation. (A). Representative images of eco-guided ultrasounds showing the needles at the site of the muscle, where the biopsies had been performed in the CTR and ABL animals. The presence of the needle is indicated by the blue and red arrow heads. (B). Representative images of biopsies derived from CTR and damaged muscle (30, 60, 90, 150 and 180 days after injury). We reported the biopsy derived from undamaged muscle (CTRL) just in a representative image
