Fig. 7From: TGF-β regulates nerve growth factor expression in a mouse intervertebral disc injury modelEffect of a TGF-β inhibitor on Ngf expression in vivo. SB431542 or DMSO (vehicle) was intraperitoneally injected into mice with intervertebral disc injury 1 and 2 days before harvesting intervertebral discs at post-injury day 1, 3, and 7 (n = 10 for each time point). *P < 0.05 compared to vehicle. Relative Ngf expression was calculated based on Ngf expression in the vehicle-treated group at each time pointBack to article page
