Endocannabinoid signaling in synchronizing embryo development and uterine receptivity for implantation.
Abstract
There are reports of adverse effects of cannabinoids on pregnancy outcome including retarded embryo development and pregnancy failure. Thus, discoveries of endogenous cannabinoid-like lipid mediators and cannabinoid receptors raise questions about their pathophysiological roles during normal pregnancy. We previously reported that anandamide, an endogenously produced arachidonate derivative (endocannabinoid), is synthesized in the female reproductive tracts, and it acts on cannabinoid receptors expressed on the cell surface of the embryo to regulate the preimplantation embryo development and implantation in mice. This review presents genetic, molecular, physiological and pharmacological evidence that the levels of uterine anandamide and blastocyst CB1 cannabinoid receptors are coordinately regulated to synchronize preimplantation development and uterine receptivity for implantation in mice.

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.
