Representative pictures of wound repair from mechanical scratch 24 h after NIV and DON cells treatment (0.5–2.5 µM).

<p>Black dotted-line indicates the edge of the wounded area at the starting time (panel A). Quantitative analysis of the wound repair 24 h after making the scratch. For each condition ten different cells were randomly selected to measure the migration distances covered every 10 min from the initial time up to the end of incubation time (***P<0.001 <i>vs</i> control; °°°P<0.001 vs DON; panel B). Data are expressed mean ± s.e.m. from at least three-independent experiments. Bar = 200 µM.
