Level of Transduction Necessary to Obtain a Complete Correction of the Phenotype
CEP mice were transplanted with HSCs transduced with the therapeutic ESpUROS-EFpGFP vector (same experiments as in Figure 4C), and the percentages of fluorocytes and GFP+ WBCs were determined for each mouse at 4 and 12 weeks. In the right part, skin photosensitivity was assayed 20 weeks after transplantation: (◆), mice with severe skin photosensitivity; (), mice with mild photosensitivity; and (◇) mice without any macroscopic or microscopic lesions.
