Figure 1. Multi-lineage reconstitution capacity is restricted to the low mitochondrial activity cell fractions.
(a) Competitive transplantation strategy used to assess multi-lineage blood reconstitution levels from peripheral blood after 4, 8 and 16 weeks. (b,c) Within LKS, which contain all multipotent stem and progenitor cells in the BM, long-term multi-lineage HSC function is restricted to TMRMlow cells (LKS:TMRMlow) (n=8 for each condition; error bar: s.e.m.; t-student, ***P<0.001). (d,e) In the phenotypically defined ST-HSC compartment, stemness is restricted to TMRMlow cells (ST-HSC:TMRMlow) (n=9 for each condition; error bar: s.e.m.; t-student, **P<0.01). (d,f) In the phenotypically defined LT-HSC compartment, stemness is restricted to TMRMlow cells (LT-HSC:TMRMlow) (n=9 for each condition; error bar: s.e.m.; t-student, ***P<0.001).
