Expression levels of insulin-like growth factor-1 (IGF-1) (A) and transforming growth factor-β1 (TGF-β1) (B) mRNAs in the contralateral, control tendons (white bars) and the transferred tendons (gray bars) are presented as fold changes relative to 18S rRNA values. The x axes denote the period after the operation. #Significantly different (p < 0.05) compared with the corresponding control-tendon value. †A significant difference (p < 0.05) between the one-day and four-week groups of transferred tendons.
