Figure 4From: Glycosaminoglycan profiles of repair tissue formed following autologous chondrocyte implantation differ from control cartilageProportions of chondroitin sulphate (CS), hyaluronan (HA), and keratan sulphate (KS) in the biopsies. Proportions of HA, CS, and KS in biopsies from (a) patients 1 year after autologous chondrocyte implantation and (b) controls. Each glycosaminoglycan (GAG), with its constituent disaccharide and monosaccharide component, is expressed as a total percentage of GAGs analysed by fluorophore-assisted carbohydrate electrophoresis.Back to article page
