The selection of specific miRNAs by exosomes and their release from cultured melanocytes after exposure to solar UVR (UVA+UVB) have activities in inducing these cells into a premature senescence. In this analysis, human TaqMan microRNA array cards A+B were used to measure the relative expression of miRNAs in exosomes isolated from the irradiated and un-irradiated melanocytes. Overall design: QM-0 mJ and QMa, b, c- 25mJ, represent experimental replicates for both Card A and B. Experiments were performed using Applied Biosystems TaqMan Array Human microRN A A+B cards v3.0, catalog # 444913
