Figure S1. Acid phosphatase histoenzymatic staining in the two muscle biopsies obtained from the treated case before (A) and after (B) ERT treatment. After ERT, muscle shows improved muscle pathology, consisting in a lower proportion of fibers with increased lysosomal activity and a generalized increase in fibers' size.
