Abstract

It has been proposed that the biological clock underlying the limited division potential of eukaryotic cells is telomere length. We assayed telomerase activity in single cells of the hematopoietic and immune systems. We examined hematopoietic stem cells at four stages of differentiation, lineage-committed progenitors, and mature myeloid and lymphoid cells. The frequency of telomerase-expressing cells within each population was proportional to the frequency of cells thought to have self-renewal potential. Among bone marrow hematopoietic stem cells, 70% exhibited detectable telomerase activity. The telomerase-expressing somatic cells observed in this study are not thought to be immortal, and expression was not correlated with cell cycle distribution or differentiation state. This study demonstrates that the developmental characteristic most consistently associated with telomerase expression is self-renewal potential.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Terc is specific to cells of hematopoietic origin.

    “our data suggest that Terc is specific to cells of hematopoietic origin.”

    From A mouse tissue atlas of small noncoding RNA (2020) · cites this paper as [39]

  • In stem cell and progenitor cell compartments, TERT serves an important role in keeping telomeres sufficiently long and stable to prevent the adverse consequences of dysfunctional telomeres on cell viability and chromosomal stability.

    “In stem cell and progenitor cell compartments3–5, TERT serves an important role in keeping telomeres sufficiently long and stable to prevent the adverse consequences of dysfunctional telomeres on cell viability and chromosomal stability6–8.”
  • In normal tissues, TERT is expressed in stem cells and in progenitor cells.

    “In normal tissues, TERT is expressed in stem cells and in progenitor cells3, but its role in these compartments is not fully understood.”

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.
