Prom1 expression does not mark a stem/progenitor population in the mouse oviduct epithelium
Bibliographic record
Abstract
Summary The oviduct or fallopian tube is the site of fertilization and preimplantation embryonic development. The epithelium lining the oviduct consists of multiciliated and secretory cells, which support fertilization and preimplantation development, however, its homeostasis still remains poorly understood. CD133/ Prom1 has been used to identify adult stem cell populations in various organs and often associated with cancer stem cell property. Using a Cre-recombinase based lineage tracing strategy, we found that CD133/ Prom1 expression was not associated with a stem/progenitor population in the oviduct but marked a sub population of multiciliated and secretory cells which did not propagate. Interestingly, Prom1 expressing secretory cells rapidly transition to multiciliated cells and progressively migrate to the tips of epithelial folds in the ampulla. Our results show that CD133/ Prom1 expression cannot be used as a progenitor/stem cell marker in the mouse oviduct.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
