Abstract
The potential of a neural stem cell line to acquire cholinergic characteristics was studied in transplants injected into the septum/diagonal band nuclei of young adult rats and mice. The stem cells integrated within the nuclei and survived for up to 9 months. Three methods were used to identify the grafted cells and to show differentiation into astrocytes and neurons. Enhanced survival of the stem cells occurred in the host brain with a previous lesion of the fimbria-fornix pathway. Differentiated cells acquired neuronal-like features including the expression of neurofilament subunits. In lesioned hosts, subpopulations of the grafted cells acquired a cholinergic neuronal phenotype and expressed choline acetyltransferase and the p75 neurotrophin receptor. Cells that developed into astrocytes were often associated with blood vessels and expressed glial fibrillary acidic protein. The results further exemplify the potential of stem cell lines and the property of site-specific differentiation when this line is transplanted to the cholinergic system of the adult brain.

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
