Figure 4From: Comparison of glucose derivatives effects on cartilage degradation Effects of Glc, GlcN-S, GlcA and GlcN-HCl on the release of HA (A), s-GAG (B) and MMP-2 (C) from chondrocytes. Chondrocytes were co-treated with 10 ng/ml IL-1β and various concentrations of each chemical (5, 10, 20 mM) for 24 hours. The conditioned media were analyzed for HA, s-GAG and MMP-2 activity as described in the Experimental section. *,** Denotes a value that is significantly different (p<0.05 and p<0.01, respectively) from the IL-1β control.Back to article page
