Real-time PCR of Col8a1 mRNA of MMCs in response to different cytokines. Wild-type MMCs were stimulated with 25 ng/ml EGF, bFGF, PDGF-BB, or TGF-β1 for 12, 24, and 48 h. After 12 h (A) strong Col8a1 expression was seen by PDGF-BB and bFGF and none by TGF-β1 and EGF. TGF-β1 was the strongest inductor of Col8a1 after 24 h followed by PDGF-BB, EGF, and bFGF (B). C: Stimulation for 48 h with TGF-β1 still had an effect on the Col8a1 expression, but none by bFGF, EGF, and PDGF-BB. Bars represent SE; *P < 0.05.
