Abstract: | Summary We examined the morphological expression of dystrophin in the intrafusal muscle fibers in skeletal muscle from normal human and Duchenne muscular dystrophy (DMD) patients, using antisera against the N-terminal and C-terminal regions of dystrophin. The intrafusal fibers of normal muscle express dystrophin on their cell surface membrane, but those of DMD muscle do not.Abbreviation DMD Duchenne muscular dystrophy |
