Abstract
The Notch signalling pathway regulates proliferation, cell death and cell type specification that is critical for organogenesis. Mouse models carrying mutations in the Notch signalling pathway display defects in development of the placenta, suggesting that this pathway is required for placental development. In particular, Notch1 mutant embryos exhibit abnormal placental morphogenesis and arrest early in development. However, expression of Notch1 gene has not been detected during placental development. Trophoblast stem cells are derived from the precursor of the placenta and express Notch1. We report that Notch1 is also expressed in differentiated trophoblast cells. Under standard differentiation conditions, Notch1 expression ceases by day 6. Furthermore, the activated NOTCH1 intracellular domain is enriched at the nucleolus of trophoblast stem cells and differentiated trophoblast cells. Our results suggest that NOTCH1 is active in both trophoblast stem cells and differentiated trophoblast cells.

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
