A Portal Blood Factor as the Humoral Agent in Liver Regeneration

Fisher, Bernard, Szuch, Patricia, Levine, Morton, Fisher, Edwin R.·1971·Science

Abstract

It was demonstrated, by use of extracorporeal cross-circulation, that a humoral factor responsible for liver regeneration does not arise from the liver remnant. While intact livers of normal rats incorporated [methyl- 3 H]thymidine in proportion to the amount of liver removed in the partner, the greatest response occurred after a total hepatectomy. Evidence from portacaval-shunted, partially hepatectomized animals connected to normal members indicates that the factor is in portal blood and that the onset of regeneration is the result of a quantitative imbalance between the available portal blood factor and the number of liver cells present.

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?

  • In experiments where the portal circulations of two animals are connected via a shunt, hepatectomy in one animal induces liver growth in the other, despite the absence of direct liver tissue damage.

    “Moreover, in experiments where the portal circulations of two animals are connected via a shunt, hepatectomy in one animal induces liver growth in the other, despite the absence of direct liver tissue damage[40,41].”
  • Mitogenic signals for hepatocytes are transported in the blood and induce immediate early genes within 30 minutes after partial hepatectomy.

    “Convincing evidence has been found that mitogenic signals for hepatocytes are transported in the blood 2,3 and that they induce a number of immediate early genes within 30 minutes after PH. 4”

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.
