In vitro exposure of pig neonatal isletlike cell clusters to human blood
Bibliographic record
Abstract
BACKGROUND: Pig islet grafts have been successful in treating diabetes in animal models. One remaining question is whether neonatal pig isletlike cell clusters (NICC) are resistant to the early loss of islets from the instant blood-mediated inflammatory reaction (IBMIR). METHODS: Neonatal isletlike cell clusters were harvested from three groups of piglets-(i) wild-type (genetically unmodified), (ii) α1,3-galactosyltransferase gene-knockout (GTKO)/CD46, and (iii) GTKO/CD46/CD39. NICC samples were mixed with human blood in vitro, and the following measurements were made-antibody binding; complement activation; speed of islet-induced coagulation; C-peptide; glutamic acid decarboxylase (GAD65) release; viability. RESULTS: Time to coagulation and viability were both reduced in all groups compared to freshly drawn non-anticoagulated human blood and autologous combinations, respectively. Antibody binding to the NICC occurred in all groups. CONCLUSIONS: Neonatal isletlike cell clusters were subject to humoral injury with no difference associated to their genetic characteristics.

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.
