To assess whether CXCR3 is also expressed by melanoma cells in metastatic tumour tissues, we performed immunofluorescence and confocal microscopy from normal skin and melanoma metastases, using anti-CXCR3 (Alexa-488) antibody, anti-CD144 (Alexa-633) antibody and phalloidin-568. This evidence concerns the gene CDH5 and melanoma.
