Abstract
The Notch signaling pathway plays a critical role during mammalian development. To bypass embryonic lethality associated with constitutive Notch1 signaling, we created transgenic mice with a floxed beta-geo/stop signal between a cytomegalo virus promoter and the constitutively active intracellular domain of Notch1 (IC-Notch1). IC-Notch1 is activated upon introduction of Cre recombinase and it is coexpressed with an enhanced green fluorescent protein or human placental alkaline phosphatase reporter. We created three IC-Notch1 transgenic mouse lines and crossed them to a general Cre deletor mouse line, pCX-Cre. The double transgenic IC-Notch1/pCX-Cre embryos have widespread expression of IC-Notch1 and reporters and die before 10.5 days of gestation. Morphological and histological analysis of the double transgenic embryos indicated growth arrest and various developmental defects, including lack of neural tube closure, disorganized somites, and disrupted vasculature. The conditional IC-Notch1 expressing transgenic mice provide a unique tool to investigate the Notch pathway using tissue-specific Cre mice and inducible Cre systems.

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
