Extended Data Fig. 5: Genotyping analysis of patient single CD34+ cell expansions.

CD34 + cells were sorted by MACS from bone marrow cells of patients 9 months after transplantation, and their single-cell expansions were analyzed for genotype by sanger sequencing. It was found that 88.3% (n=77) and 79.8% (n=104) of the CD34+ cells of the two patients were biallelic editing.
