mRNA levels of CD44, TLR-2 and TLR-4 in human articular chondrocytes cultured in the absence or presence of IL-1β, P15-1, and HMWHA. Human articular chondrocytes after reaching confluency were serum-starved for 24 h followed by treatment with IL-1β, IL-1β and P15-1, IL-1β and HMWHA, or IL-1β, P15-1 and HMWHA for 24 h. mRNA levels of CD44, TLR-2 TLR-4 were determined by real-time PCR using SYBR Green and normalized to the level of 18S RNA. Data were obtained from triplicate PCRs using RNA from 3 different cultures. Values are the mean ± SD.
