The distribution of cellular turnover in the human body

Sender, Ron, Milo, Ron·2021·Nature Medicine

Abstract

We integrated ubiquity, mass and lifespan of all major cell types to achieve a comprehensive quantitative description of cellular turnover. We found a total cellular mass turnover of 80 ± 20 grams per day, dominated by blood cells and gut epithelial cells. In terms of cell numbers, close to 90% of the (0.33 ± 0.02) × 10 12 cells per day turnover was blood cells.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Differentiated cell types in adult organs have different turnover rates; some last a lifetime while others are continuously lost and replenished quickly.

    “The cell types that build each organ are subject to different turnover rates. Some differentiated cell types can last a lifetime, such as neurons in the brain or cardiomyocytes in the heart. Other differentiated cell types are continuously lost and replenished quickly, such as red blood cells, monocytes and epithelial cells of the skin and intestine2.”

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.
