Abstract

To study telomere length dynamics in hematopoietic cells with age, we analyzed the average length of telomere repeat sequences in diverse populations of nucleated blood cells. More than 500 individuals ranging in age from 0 to 90 yr, including 36 pairs of monozygous and dizygotic twins, were analyzed using quantitative fluorescence in situ hybridization and flow cytometry. Granulocytes and naive T cells showed a parallel biphasic decline in telomere length with age that most likely reflected accumulated cell divisions in the common precursors of both cell types: hematopoietic stem cells. Telomere loss was very rapid in the first year, and continued for more than eight decades at a 30-fold lower rate. Memory T cells also showed an initial rapid decline in telomere length with age. However, in contrast to naive T cells, this decline continued for several years, and in older individuals lymphocytes typically had shorter telomeres than did granulocytes. Our findings point to a dramatic decline in stem cell turnover in early childhood and support the notion that cell divisions in hematopoietic stem cells and T cells result in loss of telomeric DNA.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Telomere length of naive T cells is longer than that of memory T cells.

    “Moreover, TL naive T cells are longer than that of memory T cells [224].”
  • T-cell telomere length declines with age.

    “T‐cell telomere length declines with age (Rufer et al, 1999), suggesting they have undergone replicative senescence from repetitive divisions.”
  • Mean leukocyte telomere length is a surrogate for the mean in a mixed cell population, and telomere length is mosaic across cell types.

    “When examining telomere measurements within a mixed cell population, it is important to note that this is a surrogate marker of the mean in a heterogeneous cell population and that telomere length is mosaic, reflecting the telomere length regulation and replicative history of each cell type51,52.”

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.
