title: [Secretion of alpha-L-fucosidase by human embryonal skin fibroblasts].
abstract: The amount of alpha-L-fucosidase secreted by normal human fibroblasts was higher in the medium containing 10% bovine serum than in the medium containing 0.1% bovine serum. Glycosidase secretion was twice higher at the advanced than at the initial stage of subcultivation. Extracellular activity of alpha-L-fucosidase from 3 different fibroblast strains differed insignificantly in the medium containing 0.1% bovine serum, while intracellular activity of the enzyme in these strains was altogether different. The results suggest that the lysosomal glycosidase secretion is determined by the level of cellular endocytosis.
