Figure 2

Identification of cancer stem cells using stem cell markers and functional assays. Several techniques have been described to identify cancer stem cells (CSCs) and to isolate them by immunomagnetic sorting, flow cytometry, or cell culture. HA: hyaluronic acid; red circle: Hoechst 33342; blue circle: Rhodamine 123; ALDH: aldehyde dehydrogenase; orange triangle: BODIPY-aminoacetaldehyde (substrate); green triangle: BODIPY-aminoacetate.
