Abstract

It has been difficult to establish whether we are limited to the heart muscle cells we are born with or if cardiomyocytes are generated also later in life. We have taken advantage of the integration of carbon-14, generated by nuclear bomb tests during the Cold War, into DNA to establish the age of cardiomyocytes in humans. We report that cardiomyocytes renew, with a gradual decrease from 1% turning over annually at the age of 25 to 0.45% at the age of 75. Fewer than 50% of cardiomyocytes are exchanged during a normal life span. The capacity to generate cardiomyocytes in the adult human heart suggests that it may be rational to work toward the development of therapeutic strategies aimed at stimulating this process in cardiac pathologies.

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?

  • Between 0.45 and 1% of human cardiomyocytes renew per annum.

    “Bergmann et al. estimated that between 0.45 and 1% of human cardiomyocytes renew per annum.”

    From The Hippo signal transduction network for exercise physiologists (2016) · cites this paper as [14]

    The paper’s Abstract reports approximately 1% annual renewal at age 20, supporting the claim’s upper figure. It reports 0.3% at age 75, however, so 0.45% is not the lower bound of the age-dependent rates it estimates. (LLM, conf=0.89)

    Experimental — accuracy not yet measured
  • By age 50, 40% of human cardiomyocytes had emerged after birth.

    “Furthermore, they showed that by the age of 50, 40% of the cardiomyocytes had emerged after birth (14).”
  • During aging the cell turnover rate declines for several highly-mitotic tissues.

    “During aging the cell turnover rate declines for several highly-mitotic tissues.”

    From Programmed cell death in aging (2015) · cites this paper as Bergmann et al., 2009

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.
