Effect of TGF-β and a TGF-β inhibitor on Ngf expression and NGF production in vitro. A RT-PCR for Ngf. Disc cells were incubated with α-MEM control, TGF-β, or TGF-β/SB431542 for 6 and 24 h. Relative expression was calculated based on expression in control samples. B ELISA for NGF. Disc cells were incubated with α-MEM control, TGF-β, or TGF-β/SB431542 for 6 and 24 h. *P < 0.05 compared to control
