Abstract
Using immunocytochemical methods, the localization of dystrophin, the gene product affected in Duchenne muscular dystrophy (DMD) in aneural, differentiating human muscle cultures, was studied. Dystrophin was not demonstrable in undifferentiated myoblasts from control patients and from two patients with DMD. After myoblast fusion, the protein was found in circumscribed sarcoplasmic patches, in the perinuclear area, and along the surface of all normal multinucleate myotubes, with more mature myotubes showing predominantly sarcolemmal distribution. There was no staining in myotubes from one DMD patient and only faint diffuse fluorescence in myotubes from the second affected boy, however. These data provide further evidence that dystrophin is a sarcolemma-associated protein, that it is developmentally regulated, and that it is absent or greatly reduced in quantity in skeletal muscle cultures from patients with DMD.
