ZFNs induces apoptosis and inhibits proliferation of CML cells. K562 and K562/G01 cells were respectively nucleofected with pAd-Track, ZFN-L, ZFN-R, Donor or ZFN-L/R and donor. a The percentage of cell apoptosis was detected by flow cytometry. b Morphologic changes of apoptotic cells were detected by DAPI stain. The arrows indicate the prominent apoptotic morphology. c Cleavage of PARP and Caspase-3 was detected by western blot. d The effect of ZFNs on CML cell proliferation was assessed by CCK-8 assay. e Treated cells were plated in 24-well plates with methylcellulose and colonies were counted after 2 weeks. Data are expressed as the means ± SD. **P < 0.01 vs. Controls
