Figure 8From: Activation of caspase-dependent apoptosis by intracellular delivery of cytochrome c-based nanoparticles Study of DAPI and propidium iodine (PI) colocalization, for the detection of apoptotic cells. Selective induction of apoptosis observed in HeLa cells incubated with the PLGA-S-S-Cyt c NPs. No cellular apoptosis observed in untreated HeLa cells or when incubated with PLGA-S-SLA NPs.Back to article page
