Postmortem recovery of proliferative fibroblasts up to three days in livestock ear skin stored at 35°C
Bibliographic record
Abstract
Effect of elevated temperature (35°C) on postmortem survival of cells in goat, sheep and bovine tissues was studied. Skin explants (n = 30; 2-3 mm2) were cultured in petri dishes after 2, 24, 48, 72, 96 and 120 hours of postmortem interval in DMEM media supplemented with 10% FBS, 50 units/mL of penicillin, 50 µg/mL of streptomycin and 2.5 µg/mL of fungizone. Outgrowth of cells around the explants was observed up to 72 h in sheep, 48 h in bovine and 24 h in goats. In general, the number of explants exhibiting outgrowth as well as the level of confluence decreased with increasing postmortem time interval. Secondary cultures established from primary cells for 72 h postmortem interval show cytogenetically stable chromosomes with 54XX[17] normal female sheep karyotype, comparable cell morphology, and growth curve to that of fresh tissue derived cells. Till date these cells have been passaged 21 times and show normal growth. These results suggest that normal, proliferative cells can be recovered from skin tissues stored at an elevated temperature of 35°C in livestock from 24-72 h of postmortem interval. Reprogramming of these cells to clone the dead animals or their use for cell therapies remain to be seen in future.

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.
