摘要: The objective of this study was to investigate the effects adenovirus vector (Ax-)mediated gene transduction E. coli β-galactosidase (LacZ) and transforming growth factor-β1 (TGF-β1) into a human chondrocyte-like cell line (HCS-2/8). expression transduced genes their periods were examined by 5-bromo-4-chloroindolyl-β-D-galactoside (X-gal) staining, Northern blotting, ELISA, Western blotting. To assess influence TGF-β1 transduction, mRNAs type II collagen, proteoglycan core protein, matrix metalloproteinase-3 (MMP-3), tissue inhibitor metalloproteinase-1 (TIMP-1) Staining with X-gal indicated that 99% cells. Expression in cells continued for at least 21 days. Transduction enhanced mRNA expressions collagen but suppressed MMP-3 These results indicate Ax is useful chondrocyte therapy, it could be an efficient mediator transduction.
