Figure 4: IMD-0354 inhibits side population of CSCs in human NSCLC cells. Side population of CSCs as measured by FACS and Hoechst 33342 dye efflux inhibition by reserpine in A549 (A) and A549Luc (B). Dose curves of IMD-0354 effects on side population of CSCs were assessed in A549 (C) and A549Luc (D). Data are shown as mean ± SEM.
