KITLG and anemia (phenotype): CBC analyses performed on blood samples taken at 30, 45, 60, 75, 90 and 140 days post-treatment from mice in each group showed persistent correction of the anaemia based on blood haemoglobin levels in the mice treated with SCF plus the γtcPNA4/donor DNA NPs (Fig. 4b), with elevation of the blood haemoglobin levels into the normal range.
