Muscle biopsy findings in MDC1A-patients included in the study. (A) Muscle biopsy cryostat sections stained with hematoxylin and eosin (HE) and immunofluorescence staining with anti-laminin-211 antibodies reveals absent immunoreactivity in the patient-derived sections. (B) Immunofluorescence staining of muscle cryostat sections with anti-laminin-511 antibody reveals in increased immunoreactivity in muscle biopsies of MDC1A-patients as indicated for two representative cases shown here. Ctrl, control muscle; numbers 1, 2, 3, 4, 5, and 6 refer to muscle biopsies derived from MDC1A-patients with the corresponding patient numbers listed in Table 2.
