Effect of culture media on expression levels of cartilage signature genes in bovine articular chondrocytes in collagen sponges. Media contained 5% fetal bovine serum (FBS), 2% Nutridoma (Nut) or 1% ITS+3. Gene expression levels of collagen type II (COL) and aggrecan (AGG) were measured by competitive RT-PCR and normalized to G3PDH.
