Fig. 2. The effect of PBM on cell migration of HCE-T cells. Cells were seeded into 12-well plate and grown to confluence. The wound was created by scraping confluent cell monolayers with a pipette tip. The cells were allowed to migrate for 8 h after 30 J/cm² of PBM treatment. At 0 h and 8 h after scratching, the plate was stained with 0.5% crystal violet and wound images were taken under the inverted microscope to assess the ability of the cells to migrate into the wound area. The graphs are shown as the mean ± SD of three independent experiments. **p<0.05, ***p<0.001.
