Figure 2. Rb1 and its metabolite compound K induce apoptosis of CSCs.

Figure 2

A. Viable spheres were counted using trypan blue after Rb1 or CK treatment. B. The expression of caspase-3 and the active (cleaved) proapoptotic gene caspase 3 were determined by Western blot after Rb1 or compound K treatment. Experiments were repeated three times, and data are shown as mean ± SD. *, P < 0.05 vs control.
