Abstract

One of the most important local adaptations to pregnancy is the change in maternal blood flow to the implantation site. In rodents and primates, new blood vessels form through angiogenesis, dilate and then become modified such that the blood enters into trophoblast cell-lined sinuses (hemochorial). Evidence from gene knockout mice suggests that factors from the placenta regulate the uterine vasculature. Consistent with this, trophoblast giant cells produce a number of angiogenic and vasoactive substances that may mediate these effects. Teratocarcinomas containing large numbers of trophoblast giant cells (derived from Parp1 gene-deficient ES cells) show similar 'hemochorial' host blood flow, implying that the effects are not specific to the uterine vascular bed. As in primates, murine trophoblast cells also invade into the uterine arteries of the mother. However, in normal pregnancy, dilation of the uterine arteries may be largely mediated by the effect of uterine natural killer cells.

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.
