MITF and melanoma: Gene expression (Affymetrix) (Fig. 1d) and MetaCoreTM analysis of these two populations revealed that the CD271high population, compared with the CD271low one, was enriched for processes like cell cycle, epithelial to mesenchymal transition (EMT), extracellular matrix remodeling and adhesion, and upregulation of MITF in melanoma (Fig. 1e).
