The Transcription Factor NFIL3 Is Essential for Normal Placental and Embryonic Development but Not for Uterine Natural Killer (UNK) Cell Differentiation in Mice1
Bibliographic record
Abstract
Mice ablated for the gene encoding the transcription factor Nfil3 lack peripheral natural killer (NK) cells but retain tissue-resident NK cells, particularly in mucosal sites, including virgin uterus. We undertook a time course histological study of implantation sites from syngeneically (Nfil3(-/-)) and allogeneically (BALB/c) mated Nfil3(-/-) females. We also examined implantation sites from Rag2(-/-)Il2rg(-/-) females preconditioned by adoptive transfer of Nfil3(-/-) marrow or uterine cell suspensions to identify the Nfil3(-/-) pregnancy aberrations that could be attributed to nonlymphoid cells. Uterine NKs (UNKs) reactive and nonreactive with the lectin Dolichos biflorus agglutinin (DBA) differentiate, localize, and mature within Nfil3(-/-) implantation sites, although at reduced abundance. The DBA nonreactive UNK cells were enriched following Nfil3(-/-) marrow transplantation. Uterine lumen closure, early embryonic development, and differentiation of antimesometrial decidua were delayed in Nfil3(-/-) implantation sites. Major disturbances to the decidual-trophoblast interface that did not lead to fetal death were attributed to NFIL3 deficiency in trophoblast. At midgestation, vessels of the placental labyrinth were enlarged, suggestive of reduced branching morphogenesis. A major term complication in most Nfil3(-/-) × Nfil3(-/-) pregnancies but not Nfil3(-/-) × Nfil3(+/-) pregnancies was dystocia. These studies highlight the differentiation potential and functions of Nfil3(-/-) UNK cell progenitors and illustrate that much of the implantation site histopathology associated with this strain is due to Nfil3 deletion in nonlymphoid cell lineages.

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.
