Figure 4From: Side population rather than CD133+ cells distinguishes enriched tumorigenicity in hTERT-immortalized primary prostate cancer cellsSP in RC-58T/hTERT/SA#4-D cells. A) RC-58T/hTERT/SA#4-D cells were analyzed for SP based on Hoechst 33342 (Sigma) or DCV staining. The RC-58T/hTERT/SA#4-D SP cells represent 1.47% of the entire population. B) 0.42% of the RC-58T/hTERT/SA#4-D SP as inhibited by 50 μM verapamil.Back to article page
