Sulfated glycosaminoglycan (s-GAG) release measured using DMMB assay in tissue culture supernatant at 72 hours post-stimulation with interleukin-1α (IL-1α), in the presence of chondroitin sulfate (A) and glucosamine hydrochloride (B) individually, and with a combination (C). Values represent the mean GAG release in μg per mg of tissue ± SEM, n = 3. One-sample Student t test was used. §Indicates P < 0.05 for a comparison with the control without IL-1α stimulation. # indicates P < 0.05 for a comparison with the control with IL-1α stimulation.
