Abstract
Labeled glycosaminoglycans (GAG) were isolated and fractionated from cultured rabbit corneal epithelium, rabbit or bovine corneal fibroblasts and rabbit bone fibroblasts that had been previously incubated with either Na235SO4 or D-glucosamine-6-3H precursors. Thus it was demonstrated that the epithelium produces GAG. The fractionations indicated that the epithelial cells predominantly synthesize GAG with a lower degree of sulfation than those produced by corneal fibroblasts. The GAG-fractionation-patterns of the corneal epithelium and bone fibroblasts were similar. Epithelkulturen der Kaninchenhornhaut und Fibroblastenkulturen der Kaninchen-oder Ochsenhornhaut sowie des Kaninchenknochens wurden entweder Na235SO4 oder D-Glucosamin-6-3H exponiert. Die Glykosaminoglykane (GAG) wurden isoliert und fraktioniert. Es wird nachgewiesen, daß das Epithel GAG synthetisiert und zwar eher geringer sulfierte als corneale Fibroblasten. Das GAG-Fraktionierungsmuster des Epithels gleicht demjenigen der Knochenfibroblasten.Keywords
