Abstract
Abstract NK cells accumulate in adult murine and human uteri during decidualization induced physiologically, pathologically, or experimentally. Adoptive transfer studies indicate that uterine NK (uNK) cells arise from circulating progenitors. However, virgin uteri contain few circulating NK1.1+CD49a− conventional NK cells, whereas NK1.1+CD49a+ tissue-resident NK (trNK) cells are abundant. In this study, we employed a novel, immune-competent NK cell–specific reporter mouse to track accumulation of uNK cells during unmanipulated pregnancies. We identified conventional NK and trNK cells accumulating in both decidua basalis and myometrium. Only trNK cells showed evidence of proliferation. In parabiosis studies using experimentally induced deciduomata, the accumulated uNK cells were proliferating trNK cells; migrating NK cells made no contribution. Together, these data suggest proliferating trNK cells are the source of uNK cells during endometrial decidualization.

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 it
