Hepatocytes primary culture from the Neotropical fish, trahira<i> Hoplias malabaricus </i>(Bloch)
Bibliographic record
Abstract
Hepatocytes were isolated and cultured from Hoplias malabaricus using a non‐enzymatic protocol. From 6·9 to 9·4 × 107 hepatocytes g−1 of liver were isolated and cell viability was 65–85%. Fish hepatocytes attached well to untreated polystyrene flasks (Corning) as well as on treated surfaces with extracellular matrix proteins, i.e. fibronectin, matrigel or type I collagen coatings. Cells rapidly started migrating and reorganizing in cord‐like groups after seeding, with spaces similar to bile canaliculi in vivo. Prominent nucleolus and euchromatin‐rich rounded nucleus, abundant mitochondria, well‐developed rough endoplasmic reticulum, polysomes and Golgi apparatus were seen under ultrastructural analysis. Cells remained functional and metabolically active after 6 days in culture. The protocol established in the current work provides the basis for further studies of native fishes for accurate in vitro toxicological studies.

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.
