Abstract

To address the fundamental question of whether or not stem cell populations age, we performed quantitative measurements of the cycling status and frequency of hematopoietic stem cells in long-lived C57BL/6 (B6) and short-lived DBA/2 (DBA) mice at different developmental and aging stages. The frequency of cobblestone area-forming cells (CAFC) day-35 in DBA fetal liver was twofold to threefold higher than in B6 mice, and by late gestation, the total stem cell number was nearly as large as that of young DBA adults. Following a further ≈50% increase in stem cells between 6 weeks and 1 year of age, numbers in old DBA mice dropped precipitously between 12 and 20 months of age. In marked contrast, this stem cell population in B6 mice increased at a constant rate from late gestation to 20 months of age with no signs of abatement. Throughout development an inverse correlation was observed between stem cell numbers and the percentage of cells in S-phase. Because a strong genetic component contributed to the changes in stem cell numbers during aging, we quantified stem cells of 20-month old BXD recombinant inbred (RI) mice, derived from B6 and DBA progenitor strains, thus permitting detailed interstrain genetic analysis. For each BXD strain we calculated the stem cell increase or decrease as mice aged from 2 to 20 months. Net changes in CAFC-day 35 numbers among BXD strains ranged from an ≈10-fold decrease to an ≈10-fold increase. A genome-wide search for loci associated with this quantitative trait was performed. Several loci contribute to the trait—putative loci map to chromosomes X, 2, and 14. We conclude that stem cell numbers fluctuate widely during aging and that this has a strong genetic basis.

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.
