Fig. 7. Total collagen expression in subsynovial fibroblasts from patients with carpal tunnel syndrome when transfected with Ad-RLN. Collagen expression decreased in the cells transfected with Ad-RLN compared to control with TGF-β1 and Ad-LacZ. *p<0.05, ^†p<0.001. TGF-β1, transforming growth factor beta 1; Ad-RLN, adenovirus-relaxin gene construct; Ad-LacZ, adenovirus LacZ gene construct.
