Adding acid alpha-glucosidase to cultures of Pompe's disease muscle has resulted in enzyme uptake and reduction in concentration of glycogen. However, bone marrow transplantation has been unsuccessful as a treatment. Immune rejection may have contributed to this failure. Twin calves share a placenta and carry lymphoreticular cells of each other's type, they become lymphoreticular chimeras in utero and immune rejection does not occur. One natural and three sets of twins produced by embryo transfer were studied in Pompe's disease cattle. Chimerism persisted throughout life and the situation was analogous to a transplant of histocompatible bone marrow stem cells. The activity of acid alpha-glucosidase in leucocytes and in biopsies of the semitendinosus muscle and the mean activity in diaphragm, spleen and lymph node obtained after death from affected twins were significantly higher than in single affected calves. Glycogen concentration was lowered in liver, spleen and lymph node but not in muscles. The affected twins showed clinical signs and changes in muscle similar to those seen in affected single calves. It is concluded that bone marrow transplantation is unlikely to be a successful treatment for Pompe's disease.
