title: Effect of chondroitin sulfate and hyaluronic acid on gene expression in a three-dimensional culture of chondrocytes.
abstract: The effect of glycosaminoglycan addition on a three-dimensional (3D) culture of porcine chondrocyte cells was investigated with a view to use in cartilage regenerative medicine. Chondroitin sulfate C increased the mRNA expression of type 2 collagen, while chondroitin sulfate A did not. Hyaluronic acid of high molecular weight markedly decreased the mRNA expression of both aggrecan and type 2 collagen, although hyaluronic acid of low molecular weight showed no apparent effect.
