Barcode profiles of long-term HSC activity. (A) Clonal composition of granulocytes at 33 weeks after transplantation in 3 recipients of LC-barcoded cells and 4 recipients of HC-barcoded cells. White bars represent barcodes that were identified in 1 recipient only, and colored bars represent barcodes that were shared between recipients. (B) Venn diagrams showing the degree of redundant barcoding between multiple recipients receiving the same starting cells. Recipients 1 and 2 received a transplant with 1 million cells, recipients 3 and 4 received a transplant with 5 million cells. Note that a portion of the barcodes shown for LC recipient 4 and HC recipient 1 are also presented in Figure 4.
