Reprogramming of Mouse Cochlear Cells by Transcription Factors to Generate Induced Pluripotent Stem Cells
Bibliographic record
Abstract
As an initial step for using technology derived from induced pluripotent stem cells (iPSCs) in the field of inner ear therapeutics, we examined the potential of four transcription factors, Oct3/4, Sox2, Klf4, and c-Myc, which are employed in the generation of iPSCs, for dedifferentiating cochlear epithelial cells. Otospheres, which are sphere-forming cells derived from dissociated cochlear epithelial cells of neonatal mice, were used as a cell source. The four transcription factors were introduced into otospheres using retroviral vectors. Virally transduced otospheres formed embryonic stem cell-like colonies that expressed markers for pluripotent stem cells and were capable of differentiating into the three germ layers in vivo and in vitro. These findings illustrate that viral transduction of four transcription factors can lead to reprogramming of cochlear epithelial cells, which may contribute to future studies of dedifferentiation of cochlear epithelial cells in tissue and identification of key molecules for otic induction.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
