Supplementary Figure 1: Inclusion of CD48 did not alter purity of HSCs gated on LSKFlk2-CD34- in either young or old mice.

a) Quantification and b) representative flow plots of CD48 expression levels in young and old HSCs (LSKFlk2-CD34-/lo), MPP1s (LSKFlk2-CD34+) and MPP2s (LSKFlk2+CD34+). Source data are included in Supplementary Table 1.
