cAT-MSC-IFN-<i>β</i> inhibits the growth of LMeC melanoma cells in a transwell system.

<p>LMeC melanoma cells were either cultured alone or co-cultured with cAT-MSC-Mock or cAT-MSC-IFN-<i>β</i> for 72 h in a 1∶1 and 4∶1 (MSC/LMeC cell) ratio. LMeC cell growth was assessed with cAT-MSCs in a transwell format, which prevented LMeC-MSC cell contact. Data are expressed as the percentage of total cells compared with that of the control. Two cAT-MSCs exhibited a potent dose-dependent inhibitory effect on LMeC cell number. The P-value was obtained using one-way ANOVA with <i>post-hoc</i> Bonferroni's multiple comparison analysis. Each data point represents the mean +SD of three independent experiments. ** <i>p</i><0.01, *** <i>p</i><0.001.
