Interleukin-1 activated chondrocytes have been identified in pig articular cartilage by immunolocalisation using a polyclonal antiserum recognising cytokine induced surface epitopes. Although chondrocytes with membrane staining were noted in all zones of the cartilage, only a proportion of the cells were positive within the range of antiserum dilution used (1:100-1:2000). Maximum staining was found after four days' treatment of cultured cartilage with pig IL-1 alpha, though weak staining was just detectable after treatment for one day at high antiserum concentration. Immunoreactivity was also shown in cartilage which had been cultured with human recombinant IL-1 alpha.
