Origin and role of distal visceral endoderm, a group of cells that determines anterior–posterior polarity of the mouse embryo

Takaoka, Katsuyoshi, Yamamoto, Masamichi, Hamada, Hiroshi·2011·Nature Cell Biology

Abstract

Anterior-posterior polarity of the mouse embryo has been thought to be established when distal visceral endoderm (DVE) at embryonic day (E) 5.5 migrates toward the future anterior side to form anterior visceral endoderm (AVE). Lefty1, a marker of DVE and AVE, is asymmetrically expressed in implanting mouse embryos. We now show that Lefty1 is expressed first in a subset of epiblast progenitor cells and then in a subset of primitive endoderm progenitors. Genetic fate mapping indicated that the latter cells are destined to become DVE. In contrast to the accepted notion, however, AVE is not derived from DVE but is newly formed after E5.5 from Lefty1(-) visceral endoderm cells that move to the distal tip. Concomitant with DVE migration, all visceral endoderm cells in the embryonic region undergo global movement. In embryos subjected to genetic ablation of Lefty1-expressing DVE cells, AVE was formed de novo but the visceral endoderm including the newly formed AVE failed to migrate, indicating that DVE guides the migration of AVE by initiating the global movement of visceral endoderm cells. Future anterior-posterior polarity is thus already determined by Lefty1(+) blastomeres in the implanting blastocyst.

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?

  • Symmetry is broken and the AP axis established through migration of AVE.

    “Symmetry is broken, and the AP axis established through the migration of AVE37.”
  • emVE-specific genes include Lhx1 and Lefty1, and AVE-specific genes include Cer1 and Hhex; exVE-specific genes include Apln and Msx1.

    “emVE-specific genes (Fig. 3c, Cluster 1) included Lhx1 and Lefty1, and AVE-specific genes Cer1 and Hhex30,32,37. ExVE-specific genes (Fig. 3c, Cluster 2) included Apln and Msx1 (Supplementary Table 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.
