Immunoprotection of rat islet xenografts by cotransplantation with sertoli cells and a single injection of antilymphocyte serum1
Bibliographic record
Abstract
BACKGROUND: Islet transplantation has become a clinical reality; however, before it can be extended to young juvenile diabetics an unlimited supply of tissue is needed and the use of chronic immunosuppression should be eliminated. This study was designed to determine whether Sertoli cells can immunoprotect islet xenografts. METHODS: Lewis rat islets were cotransplanted with Balb/c Sertoli cells in diabetic Balb/c mice treated with one injection of anti-mouse lymphocyte serum (ALS). RESULTS: When islets were transplanted alone, in combination with Sertoli cells, or in combination with ALS, mean graft survival times were 10.9+/-0.8, 14.0+/-1.2, or 12.2+/-0.7, respectively. When islets were combined with Sertoli cells and ALS, mean graft survival time increased to 64.9+/-8.1. CONCLUSIONS: Sertoli cells are able to prolong the survival of islet xenografts when combined with ALS, thereby supporting their use as a means to immunoprotect cellular grafts such as islets for the treatment of type 1 diabetes.

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.
