General descriptionThe chondrocyte is the only specialized cell type present in articular cartilage. They produce secretions to support and repair the cartilage matrix. Human chondrocytes in mature articular cartilage are post-mitotic and terminally differentiated cells. Studies on human chondrocytes have been hampered by the difficulty in obtaining sufficient numbers of primary human chondrocytes from a single joint and by variabilities among donors due to factors such as age and medical conditions.
C-28/I2 is a clonal line derived from the nonclonal T/C-28a2 cells which were immortalized via retroviral vector-mediated simian virus SV40 Large T antigen (Tag) expression.
