Abstract

Summary: The number of hematopoietic stem cells (HSC) and endothelial progenitor cells (EPC) is thought to be a marker for neovascularization and vascular repair. Because physical inactivity and aging are risk factors for cardiovascular diseases, these factors may influence the numbers of HSCs and EPCs. Therefore, we examined baseline and exercise‐induced levels of HSCs and EPCs in sedentary and trained young and older men. To study the role of aging in eight sedentary young (19–28 years) and eight sedentary older men (67–76 years), baseline and acute exercise‐induced numbers of HSCs (CD34+‐cells) and EPCs (CD34+/VEGFR‐2+‐cells) were quantified by fluorescence‐activated cell sorter (FACS) analysis. To examine the effect of chronic training, eight age‐matched trained young men (18–28 years) were compared with sedentary young men, whereas older men performed an 8‐week endurance training. Older men showed significantly lower baseline and exercise‐induced levels of HSCs/EPCs than the young men (P < 0.05). In young and older men, acute exercise significantly increased HSCs (P < 0.01), but not EPCs. The absolute increase in numbers of HSCs was attenuated in older men (P = 0.03). Apart from the lower baseline numbers of EPCs after chronic training in older men, training status did not alter baseline or exercise‐induced levels of HSCs/EPCs in young and older men. We concluded that advancing age results in lower circulating numbers of HSCs and EPCs and attenuates the acute exercise‐induced increase in HSCs. Interestingly, in young as well as in older men chronic endurance training does not affect baseline and exercise‐induced numbers of HSCs and EPCs.

  • The acute effects of exercise include improvements in the trafficking and functional capabilities of many cell types, including haematopoietic stem cells, cells of myeloid lineage, and cells of lymphoid lineage.

    “The acute effects of exercise include improvements in the trafficking and functional capabilities of many cell types, including haematopoietic stem cells (Thijssen et al. 2006), cells of myeloid lineage (e.g., monocytes, neutrophils, dendritic cells) and cells of lymphoid lineage (e.g., NK cells, B cells and T cells) (Shephard 2003; Walsh et al. 2011b).”

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.
