Fig. 8. Effects of anti-TGF-ß1 neutralizing antibody (3 µg/ml) on the steady-state mRNA level of apolipoprotein J (A), osteonectin (B), SM22 (C), TGF-ß1 (D), fibronectin (E) and p21^WAF-1 (F) at 72 hours after a series of 10 exposures of skin HDFs to UVB at 250 mJ/cm². Anti-TGF-ß1 CTL and CTL cells had no UVB exposure and were incubated with or without anti-TGF-ß1 antibodies, respectively. Statistical analysis was carried out with the Student's t-test. ns, non-significant (P>0.05); ^*, 0.05>P>0.01.
