Abstract
Transplantation of epithelial cells into cleared fat pads is a widely used technique in the study of mammary gland biology. It was first described in 1959 and has remained a valuable technique, most recently in conjunction with the analysis of mammary anlagen from knockout mice with an embryonic lethal phenotype or reproductive defect, and for mammary epithelial stem-cell assays or analysis of precancerous cells. Mammary glands, unlike most other organs, mainly develop postnatally. When the small amount of endogenous epithelium present in the fat pad of a prepubertal mouse is removed, this clearance leaves a natural microenvironment that can be repopulated with exogenously supplied epithelial cells. Cells with the appropriate developmental potential (stem cells or progenitor cells) can regenerate the epithelial portion of the mammary gland after puberty and pregnancy. The conventional clearance of the fat pad is an involved surgical procedure. We have improved the technique and minimized surgery and recovery time, while maintaining an efficient removal of endogenous epithelium from the mammary fat pad.

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
