Time-dependency on Pep27anal2 – induced apoptosis in Jukart cells. Apoptotic cells were counted among 200–400 cells in each group. The representative electron microscopic findings show apoptosis induced by etoposide or by Pep27anal2 after 4-hr incubation. (a) Control group. Some apoptotic cells were found. (b) Etoposide treated group. Apoptotic cells were more frequent than in the control group. (c) Pep27anal2 treated group. Apoptotic cells were most frequent in this group. Lead citrate and uranyl acetate staining. Scale bar measures 9.9 μm. Arrows indicate apoptotic cells.
