NODAL signaling components regulate essential events in the establishment of pregnancy
Bibliographic record
Abstract
Successful mammalian reproduction is dependent on a receptive and nurturing uterine environment. In order to establish pregnancy in humans, the uterus must i) be adequately prepared to receive the blastocyst, ii) engage in a coordinated molecular dialog with the embryo to facilitate implantation, and iii) undergo endometrial decidualization. Although numerous factors have been implicated in these essential processes, the precise network of molecular interactions that govern receptivity, embryo implantation, and decidualization remain unclear. NODAL, a morphogen in the transforming growth factor β superfamily, is well known for its critical functions during embryogenesis; however, recent studies have demonstrated an emerging role for NODAL signaling during early mammalian reproduction. Here, we review the established data and a recent wave of new studies implicating NODAL signaling components in uterine cycling, embryo implantation, and endometrial decidualization in humans and mice.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
