Intriguingly, we also found that the cancer stem cells (CSC) score, calculated using common CSC markers (EPCAM [28], CD24 [29], KRT19 [30], SOX9 [31], PROM1 [32], CD44 [33], THY1 [34], CD47 [35]), was significantly higher in the EMT-subtype (Fig. S4A & S4B). This evidence concerns the gene CD47 and cancer.
