TSP-1 release stimulated by IL-1β is not significantly decreased after carprofen + IL-1β treatment. Western blots for TSP-1 produced a band at about 125 kDa that was detected only in the presence of IL-1β. Cartilage explants were cultured for 6 days with three treatment replicates from the same individual animal (n = 3). Explant treatments: untreated control, IL-1β (10 ng/ml), carprofen (100 μg/ml), or carprofen (100 μg/ml) + IL-1β (10 ng/ml).
