CD34+ stem/progenitor cells isolated from five patients with CML-CP and one with CML-BP (ALL) (Supplementary Table S2) were infected with Cas9GFP/dualBA-sgRNA lentivirus (Cas9-BA) or control virus (NC) or without virus, and then, the GFP+ cells were sorted and used to analyze the genomic sequence alterations, fusion protein levels, cell survival, and cell colony formation. This evidence concerns the gene CP and chronic myelogenous leukemia, BCR-ABL1 positive.
