The medium was replaced by fresh medium containing 5 µM docetaxel in the absence of PAH, or the presence of 5 µM PAH. Two pictures were taken at two different points of each well immediately after wound, and 3 days after wound with 5X objective. The width of the wound was measured using ImageJ software and reported as final wound width/initial wound width in percentage. Data presented are the mean ± SEM of 3 independent experiments.
