Mean gene expression relative to GAPDH of IL-6, IL-8, VEGF, and TGFβI in the (A) synovium, (B) ligament, and (C) provisional scaffold following ACL injury. Note the log 10 scale on the y-axis. Error bars represent standard error of the mean and asterisks indicate significance determined at P < 0.05 within tissue type compared to baseline (Day 0) levels.
