Wound healing assays.

<p>(A) BHP10-3 and TPC1 cells were plated in 12-well plates, grown to confluency, and the monolayer was wounded with a pipette tip. Wound healing was documented by photography after 24 h of incubation. Scale bar = 200 µm. (B) Quantification of cell migration. The NTP significantly inhibited the migration of BHP10-3 (<i>P</i><0.001) and TPC1 (<i>P</i><0.001) cells across the denuded zone. The data represent the mean ± S.D. of three independent experiments. NS, not significant; **<i>P</i><0.01, ***<i>P</i><0.001.
