Abstract
Compared to other animals, the anatomy of the human epididymis appears unusual. The caput epididymis is composed mostly of efferent ducts with an undefined initial segment. The present study investigates the regionalization of c-ros in human epididymis by real-time quantitative RT-PCR, in situ hybridization and immunohistochemistry studies. C-ros gene encodes a receptor-type protein tyrosine kinase that is expressed in adult mice exclusively in the epithelial cells of the initial segment of the epididymis. Transgenic mice targeted for the c-ros gene lack the initial segment of the epididymis and are infertile. Real-time PCR analysis showed that c-ros mRNA is expressed all along the human epididymis with the exception of the proximal caput epididymidis, where c-ros transcript was undetectable. In situ hydridization revealed that c-ros transcript was strongly expressed by principal cells and to a lower level by basal cells. Immunohistochemical studies showed that c-ros protein distribution was similar to the transcript. These results showed that c-ros expression in the human epididymis differs from that in mice suggesting that the unusual morphology of the human epididymis may reflect species differences in gene expression along the excurrent duct.

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
