Fig. 4From: Potential therapeutic effects of N-butylidenephthalide from Radix Angelica Sinensis (Danggui) in human bladder cancer cellsThe inhibitory effect of BP on the migration of human bladder cancer cells- wound healing assay. Human bladder cancer cells were treated with 0.2% DMSO as control or 40 to 80 μg/ml BP for the indicated time points. Images of wound closures were captured using inverted microscope with 100 X magnification. The cell-free area invaded by migrated cells across the black lines were calculated by three randomized fields and quantified. The cell-free distance at 0 h were set at as 100%. Data obtained from three independent experiments and presented as mean ± S.D. from three independent experiments. Scale bar: 100 μm, * p < 0.05 versus vehicle; ** p < 0.01 versus vehicleBack to article page
