Cortex‐ and striatum‐ derived neural stem cells produce distinct progeny in the olfactory bulb and striatum
Bibliographic record
Abstract
Neural stem cells can be isolated from the mouse embryonic cortex but do not persist in the adult cortex. In contrast, neural stem cells from the striatal embryonic germinal zone persist in the adult subependyma. Emx1-lineage analysis revealed that cortex-derived neural stem cells survive and migrate ventrally into the subependyma where they intermix with the host striatal neural stem cells [S. Willaime-Morawek et al. (2006)J. Cell Biol. 175, 159-168]. Cortex-derived cells proliferate faster in the subependyma and reach the olfactory bulb earlier than striatum-derived cells. In the olfactory bulb, cortex-derived cells produce more cells and more dopaminergic neurons in the glomerular layer than striatum-derived cells. Cortex-derived cells also give rise to more astrocytes and less neurons in the striatum than striatum-derived cells. Thus, history matters; cortex-derived neural stem cells in the subependyma give rise to progeny in the olfactory bulb and striatum but in different proportions than striatum-derived neural 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.
