IC50 values for doxorubicin and docetaxel depending on the level of CD146 expression.

The specific MFI represents the ratio of the mean fluorescence intensity for the CD146 antibody over the mean fluorescence intensity of the isotypic control (mean ± standard error of the mean of at least six independent experiments). IC50 is expressed as the mean (± standard error of the mean) for six different experiments. Results were analyzed with the Wilcoxon matched pairs test and considered as significant when p<0.05.
