SOX2 and cancer: CD24 in combination with CD44 and/or CD133 (PROM1) has been highlighted as cancer stem cell markers (in combination with NANOG, OCT3/4, and SOX2), and a cell‐type‐dependent correlation of CD24 to the chemokine receptor CD184 (CXCR4) has been shown [64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75].
