ZFNs induces apoptosis and inhibits proliferation of CD34⁺ cells from CML patients. CML CD34⁺ cells were collected from patients and treated with ZFN-L/R and Donor plasmid, respectively or together. a The editing efficiency of ZFNs on bcr-abl gene editing was quantified by NotI restriction enzyme. CML-P1, CML-P2, CML-P3 and CML-P4 are abbreviations for CML-Patient 1, CML-Patient 2, CML-Patient 3 and CML-Patient 4 respectively. Cell viability was assessed via CCK8 assay (b), (c), (d), (e) and the percentage of apoptotic cells was determined by FCM (f). The data are shown as the mean ± SD. **P < 0.01 vs. Controls and ***P < 0.001 vs. Controls
