Figure 3. Chemosensitivity of FACS-enriched HLE subpopulations.
Chemosensitivity of HLE subpopulations to cisplatin (A), doxorubicin (B) and sorafenib (C) was assayed with WST-1 reagent after treatment for 24 hours and expressed as optical density value per 100 μg protein content. *, **, *** p<0.05, 0.01 and 0.005 compared to HLE CD133+/ALDHhigh subpopulation.
