Figure 3

Inverted microscopy micrographs of four different cancer cell lines before and after treatment with 250 μg/mL of EEP for 24 h at actual magnification of 100x. Control cells demonstrated dense cell populations with very few rounded cells. Treated cells showed increased numbers of rounded cells with compromised cell density and suspended appearance with apoptotic blebs.
