CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: Although the AAV capsid mutant was established onto a CML cell line, for both CML cells (%GFP+aav2: 0.54% ± 0.29%; %GFP+mut.: 1.75% ± 0.45%) and CD34+ PBPC (%GFP+aav2: 1.19% ± 0.23%; %GFP+mut.: 4.21% ± 3.40%) an increase in gene transfer efficiency with the K562 clone EARVRPP was observed compared to the standard rAAV2 vector (Figure 2), which was significant for the CML (p = 0.03) group.
