Migration of RAW 264.7 cells is increased in ECPsp-conditioned medium. The macrophages were chemoattracted by serum free medium (SFM, upper left), conditioned medium culturing BEAS-2B cells (Ctrl, lower left), conditioned medium culturing eGFP/BEAS-2B cells (eGFP, upper right) and conditioned medium culturing ECPsp-eGFP/BEAS-2B (ECPsp-eGFP, lower right). The folds of migrating RAW 264.7 cells is increased in ECPsp-conditioned medium by 2.93- and 3.11-fold relative to medium conditioned by BEAS-2B and eGFP/BEAS-2B cells, respectively. The average, with standard deviation, was derived from three independent experiments. *** p <0.001.
