OBJECTIVE To determine the effect of avian chondroitin sulfate (CS) on interleukin-1beta (IL-1beta)-induced expression of genes related to catabolic, anabolic and inflammatory aspects in chondrocytes cultured in hypoxic alginate beads. DESIGN Articular chondrocytes from bovine metacarpal joint were isolated and cultured in alginate beads, using low oxygen(More)
OBJECTIVES To determine the effect of chondroitin sulfate (CS) on inflammatory mediators and proteolytic enzymes induced by interleukin-1β (IL-1β) and related to cartilage catabolism in murine osteoblasts. DESIGN Osteoblasts were obtained by enzymatic digestion of calvaria from Swiss mice and cultured for 3 weeks as a primary culture. Cells were then(More)
