Abstract
The developmental origin of a pancreatic precursor cell could provide clues to properties that may be crucial to its molecular regulation and therapeutic potential. Previously, lineage tracing experiments showed that multipotent precursors in mouse islets had a pancreatic and not a neural crest developmental origin. However, a different Cre reporter system reveals that there is, in fact, a rare population of proliferative cells in the pancreas that is descended from the Wnt1 neural crest lineage, in addition to the majority population descended from the Pdx1 pancreatic lineage. These two proliferative cell populations are distinct in their gene expression and differentiation potential. This evidence suggests that there are at least two distinct types of precursors present in adult pancreatic islets, one of pancreatic origin and one of neural crest origin.

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 it
