Telomerase is required to slow telomere shortening and extend replicative lifespan of HSCs during serial transplantation
Abstract
Telomere shortening ultimately limits the replicative life span of cultured human somatic cells. Telomeres also shorten during replicative aging in vivo in hematopoietic cells, including early hematopoietic progenitors and hematopoietic stem cells (HSCs), from humans and mice, despite readily detectable levels of telomerase in these cells. To assess the relevance of telomerase to the long-term replicative capacity of HSCs in vivo, we serially transplanted HSCs from wild-type and telomerase-deficient mice until exhaustion and monitored telomere length in HSCs during this process. Telomerase-deficient HSCs could be serially transplanted for only 2 rounds, whereas wild-type HSCs could be serially transplanted for at least 4 rounds. Furthermore, the rate of telomere shortening was increased approximately 2-fold during serial transplantation of telomerase-deficient HSCs. These findings suggest that one role for telomerase in the HSC is to partially counter the rate of telomere shortening during division of HSCs, thereby preventing premature loss of telomere function and providing added replicative capacity.

“In agreement with these findings, studies of telomerase knockout mice revealed short dysfunctional telomeres that profoundly impaired progenitor cell function in actively renewing tissues leading to atrophy and reduced regenerative potential, whereas more quiescent low-turnover tissues such as muscle were unaffected (Allsopp et al., 2003; Lee et al., 1998; Rudolph et al., 1999).”

“The generation of mouse models lacking telomerase activity, TERT and Terc knockout mice (Blasco et al., 1997; Liu et al., 2000) previously resulted in the demonstration that telomerase plays a crucial role in self-renewal of adult stem cells in high turnover tissues such as blood, liver, skin and testis (Allsopp et al., 2003; Lee et al., 1998).”

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.
