Distribution of nestin protein: Immunohistochemical study in enteric plexus of rat duodenum
Bibliographic record
Abstract
The intermediate nestin filament is expressed in neural stem cells, neuroectodermal tumors and various adult tissues under situations that reproduce developmental phases, e.g., physiological renewal of certain cell types, tissue regeneration, and healing or revascularization. In the human gastrointestinal tract, nestin has been reported in glial cells and interstitial cells of Cajal. We examined by immunohistochemistry the appearance and distribution of nestin protein in enteric ganglia of rat duodenum. Through the myenteric and submucosal plexuses, a high number of nestin-positive cells were visualized in this specie. The nestin-positive cells were smaller and more numerous than enteric neurons. They were present both within and around ganglia. The results of this study suggest that the rat enteric glial cells (EGCs) are rich in nestin, a protein usually associated with dividing or migrating cells and the dynamic reorganization of nestin filaments during the cell cycle. EGCs could function as enteric stem cells.

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.
