Abstract

We have studied the role of the basic helix–loop–helix–PAS transcription factor EPAS-1/hypoxia-inducible factor 2α in vascular development by gene targeting. In ICR/129 Sv outbred background, more than half of the mutants displayed varying degrees of vascular disorganization, typically in the yolk sac, and died in utero between embryonic day (E)9.5 and E13.5. In mutant embryos directly derived from EPAS-1 −/− embryonic stem cells (hence in 129 Sv background), all embryos developed severe vascular defects both in the yolk sac and embryo proper and died between E9.5 and E12.5. Normal blood vessels were formed by vasculogenesis but they either fused improperly or failed to assemble into larger vessels later during development. Our results suggest that EPAS-1 plays an important role at postvasculogenesis stages and is required for the remodeling of the primary vascular network into a mature hierarchy pattern.

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.
