General description

The 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-20/A4 cell line was established by transfecting primary cultures of rib chondrocytes from a 5-year-old male with vectors expressing origin-defective simian virus SV40 large T antigen.

Application

This product is intended for sale and sold solely to academic institutions for internal academic research use per the terms of the “Academic Use Agreement” as detailed in the product documentation. For information regarding any other use, please contact licensing@emdmillipore.com.

Quality

• Each vial contains ≥ 1X106 viable cells.
• Cells are tested by PCR and are negative for HPV-16, HPV-18, Hepatitis A, B, C and HIV-1 & 2 viruses.
• Cells are negative for mycoplasma contamination.
• Each lot of cells are genotyped by STR analysis to verify the unique identity of the cell line.

Storage and Stability

Store in liquid nitrogen. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.

Other Notes
