Establishment and characterization of a fibroblast cell line derived from Texel sheep
Bibliographic record
Abstract
A Texel sheep ear marginal tissue fibroblast cell line (named TSF19) was successfully established by using a primary explant technique and cell cryoconservation technology. TSF19 cells were adherent, with a population doubling time of 24.9 h. Chromosome analysis showed that >90% of cells were diploid prior to cell passage 4. Isoenzyme analyses of lactate dehydrogenase and malate dehydrogenase showed that the TSF19 cells had no cross-contamination with other species. Tests for cell line contamination with bacteria, fungi, or mycoplasmas were also negative. Plasmids encoding the fluorescent proteins pEGFP-N3, pECFP-N1, pDsRed1-N1, and pEYFP-N1 were transfected into cells to study exogenous gene expression in the cells. The plasmid transfection efficiency was between 21.8% and 46.5%. This newly established cell line will not only preserve the genetic resources of the important Texel sheep at the cell level but will also provide a valuable resource for genomic, postgenomic, somatic cloning research.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
