Figure 2.

Dynamic membrane blebbing is present in cells treated with z-VAD-FMK after serum removal, but is absent in cells treated with STS and z-VAD-FMK. (a) Representative field of serum-free z-VAD-FMK–treated cells at 24 h. (b) Representative field of STS- and z-VAD-FMK–treated cells at 12 h. Note that some cells form neurite-like projections after STS treatment. Phase rings were purposely misaligned slightly to decrease phase “halo” and emphasize surface morphology. Bar, 30 μM.
