Figure 2: The effect of NK-lysin on SMMC-7721 cell migration. The scratch width of the different groups on SMMC-7721 cells after 24 hrs (a). Migration inhibition analysis of the various concentrations of NK-lysin and PBS (b). The migration inhibition rate of the NK-lysin group compared with the PBS group. The values are presented as the mean ± SEM (n=3), P<0.001 vs. the PBS group.
