Cytotoxic activities of polymer micelles containing CFZ in H460 (A) and select micelle formulations in RPMI-8226 (B) cell lines. Cytotoxic activities of polymer micelles containing CFZ in H460 (A) and select micelle formulations in RPMI-8226 (B) cell lines. Results are represented as percentage of cell viability of vehicle-only control. Micelle formulations containing CFZ were compared at 50 and 5 nM of equivalent CFZ concentration in H460 and RPMI-8226 cells, respectively. Data are represented as means ± S.E.M. Lin Ao et al.
