Fabry disease: cellular expression of enzyme deficiency in nerve xenografts

Human sural nerve fascicles from a patient with Fabry disease were transplanted into nude-mouse sciatic nerves to determine whether transplanted perineurial cells and smooth-muscle cells of an epineurial artery would express the genetic abnormality of the disease. Four months after grafting, both perineurial cells and smooth-muscle cells contained the cytoplasmic lamellated inclusion bodies characteristic of Fabry disease. This provided evidence of human perineurial cells and smooth-muscle cells in the regenerated xenografts.
