Abstract

A hallmark of adult hematopoiesis is the continuous replacement of blood cells with limited lifespans. While active hematopoietic stem cell (HSC) contribution to multilineage hematopoiesis is the foundation of clinical HSC transplantation, recent reports have questioned the physiological contribution of HSCs to normal/steady-state adult hematopoiesis. Here, we use inducible lineage tracing from genetically marked adult HSCs and reveal robust HSC-derived multilineage hematopoiesis. This commences via defined progenitor cells, but varies substantially in between different hematopoietic lineages. By contrast, adult HSC contribution to hematopoietic cells with proposed fetal origins is neglible. Finally, we establish that the HSC contribution to multilineage hematopoiesis declines with increasing age. Therefore, while HSCs are active contributors to native adult hematopoiesis, it appears that the numerical increase of HSCs is a physiologically relevant compensatory mechanism to account for their reduced differentiation capacity with age.

  • Direct fluorescent labeling of mouse HSCs under steady state conditions illustrated a significant and continued contribution of HSCs to nearly all steady state hematopoiesis.

    “Similarly, direct fluorescent labeling of mouse HSCs under steady state conditions illustrated a significant and continued contribution of HSCs to nearly all steady state hematopoiesis (Chapple et al., 2018; Sawai et al., 2016; Säwen et al., 2018).”

  • In blood, lineage tracing, single-cell RNA-seq and large-scale clonal analysis studies indicate that old HSCs generate fewer lymphoid cells and are skewed towards the myeloid lineage.

    “In blood, lineage tracing, single-cell RNA-seq and large-scale clonal analysis studies all indicate that old HSCs generate fewer lymphoid cells and are skewed towards the myeloid lineage23–26.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
