CD44⁺/CD24⁻ expression in ovarian cancer tissue (400× magnification). CD44⁺ cells have brown cell membrane (orange arrow). CD24⁺ cells have red cytoplasm and cell membrane (blue arrow). CD44⁺/CD24⁻ cells have a more dominant brown color than red color. A Chemoresistant ovarian cancer tissue, brown staining predominating over red. B Chemosensitive ovarian cancer tissue, almost all cells are colored red
