Figure 7From: Activation of caspase-dependent apoptosis by intracellular delivery of cytochrome c-based nanoparticles Viability of HeLa cells treated with PLGA-S-S-Cyt c NPs after 6h of incubation. Two controls were included (PLGA-SPDP, PLGA-S-S-LA NPs) and had no effect on HeLa cell viability. Asterisk (***) indicates statistical significance (p?<?0.001).Back to article page
