Abstract

Although important progress has been made recently in the elucidation of the molecular mechanisms that regulate differentiation and morphogenesis of endoderm-derived tissues such as pancreas and liver, less is known about the preliminary steps of early regional specification. Recent evidence supports the proposal that the early endoderm contains a bipotential precursor cell type for pancreas and liver. We have also previously shown that the activity of the homeobox gene Prox1 controls hepatocyte migration during liver morphogenesis. Using detailed comparative analysis of whole embryos and reverse transcriptase polymerase chain reaction of dissected embryonic endoderm, we have now determined that in the early endoderm, Prox1 expression is restricted to regions giving rise to the mammalian pancreas and liver. This finding indicates that Prox1 is one of the earliest specific markers of this commonly fated region of the mammalian endoderm.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Prox1 is only expressed by the liver and pancreas progenitors beginning at the 7-8 somite stage.

    “For example, Prox1 is only expressed by the liver and pancreas progenitors beginning at the 7–8 somite stage [43].”

    From A systematic screen for genes expressed in definitive endoderm by Serial Analysis of Gene Expression (SAGE) (2007) · cites this paper as [43]

    The Results and discussion section says Prox1 is first detected in hepatic endoderm at the 7–8 somite stage, but section 1.1 places detectable dorsal pancreatic expression later, at 15–18 somites. Figure 1 also reports expression near the node and in the hindgut, contrary to “only” liver and pancreas progenitors. Page numbers are unavailable in our copy. (LLM, conf=0.90)

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.
