Livers from normal cats and dogs, cats with mucopolysaccharidoses (MPS) I and VI, and dogs with MPS VII were analyzed biochemically and morphometrically to determine the lysosomal storage of glycosaminoglycans (GAG) in these animal models of human genetic disease. Analyses were performed on liver samples from seven normal cats ranging in age from 13 weeks to 15 months; six MPS I-affected cats ranging in age from 10 weeks to 26 months; four MPS VI-affected cats ranging in age from 9 months to 32 months; four normal dogs ranging in age from 1 month to 47 months; and three MPS VII-affected dogs, 5 days, 11 days, and 14 months of age. All of the animals were from the breeding colony at the University of Pennsylvania School of Veterinary Medicine and were maintained in accordance with national standards for the care and use of laboratory animals. Each GAG subclass was quantitated, and total GAG concentration was determined. Liver from cats with MPS I had the highest total GAG concentration (5.7 times that of the control), followed by liver from dogs with MPS VII (1.8 times) and cats with MPS VI (1.5 times). These data were very closely correlated (R2 = 0.982) with the results of the morphometric analyses of hepatocyte and Kupffer cell vacuolation associated with lysosomal storage and support the validity of both methods. This is particularly important for the quantification of total and individual GAG concentrations in tissue preparations. The values obtained should prove useful in future assessments of therapeutic regimes, such as enzyme replacement, bone marrow transplantation, and gene therapy, for these genetic diseases.
