Localization of cells from the winter flounder gill expressing a skin type antifreeze protein gene
Bibliographic record
Abstract
In situ hybridization on whole mounts and paraffin-sectioned winter flounder (Pleuronectes americanus) gill, using riboprobes specific to a skin type antifreeze protein (AFP) gene, showed a mRNA distribution associated with cells throughout the filament and the lamellae. Immunohistochemistry using antibodies for a skin-type AFP identified cells corresponding to those detected using in situ hybridization. Parallel experiments with antibodies for chloride-cell markers showed that these cells were not involved in antifreeze-protein expression. Similarly, goblet cells did not show cross-reactivity with the AFP antibodies. This general distribution suggested that pavement cells were likely involved. Reverse transcription polymerase chain reaction using gill cDNA templates and subsequent sequencing of the products confirmed the presence of skin type AFP transcripts in this tissue. Expression of a AFP in this area may act as a first line of defence against ice-crystal migration into peripheral tissues.

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.
