Culturing Olfactory Ensheathing Cells from the Mouse Olfactory Epithelium
Bibliographic record
Abstract
Olfactory ensheathing cells (OECs) are not a class of stem cell, but they are a specialized and highly plastic glial cell that can continuously support the neurogenesis and axonal regeneration of olfactory receptor neurons. Because of this, they have been transplanted into sites of spinal cord injury to test their efficacy in promoting repair. They also have been demonstrated to have some ability to support the remyelination of demyelinated axons. Although the majority of these transplantation studies have used OECs prepared from the olfactory bulb (OB-OECs), OECs also can be prepared from the olfactory mucosa, and they are thus a candidate peripherally accessible population of glia that may be effective in promoting repair in a variety of central nervous system lesions. This protocol is designed to produce a highly enriched population of OECs from the lamina propria (LP) of the olfactory mucosa (LP-OECs), which are antigenically similar to OB-OECs and bear some phenotypic similarities to embryonic Schwann cells, but may demonstrate some distinct functional differences.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
