Effect of DP on SW480 cell migration and invasion <i>in vitro</i>.

<p>A, Wound-healing assay showed that 5 μM DP did not affect movement of SW480 cells. Representative images of wound closure were taken at 0, 24, 48 and 72 h after injury under 40 × magnification (above). Bar graphs of upper panel are shown (below). Values are the means ± SD; n = 3. Ctrl, control. B, Transwell penetration assays showed that 5 μM DP did not affect migration (without Matrigel) and invasion (with Matrigel) of SW480 cells compared with the control group (above). Bar graphs showed the cell number per field of SW480 cell migration (middle) or invasion (below). Values are the means ± SD; n = 3; Ctrl, control.
