Abstract
Hereditary deafness affects about 1 in 1,600 children and GJB2 gene mutation is most frequent cause for this disease. GJB2 encodes connexin26 (Cx26), a component in cochlear gap junction. Cx26 is mainly expressed in cochlear supporting cells and fibrocytes, and forms large gap junction plaque (GJP) macromolecular complex. Recently, we have developed a method for preparing inner ear precursor cells with Cx26GJP from mouse iPS cells (Fukunaga, Stem Cell Report, 2016). In this study, we aimed for separation of inner ear progenitor cells and mass culture of the cells by simplification of the method. Methods: The cochlear feeder cells were developed from adult cochlear tissue to support cochlear differentiation. Undifferrentiated mouse iPS cells were cultured in mediums which contain several reagent cocktails on the cochlear feeder cells. Cx26 expression was analyzed by immunohistochemistry. GFP signals controlled by Nanog promotor (Nanog-GFP) were monitored as an undifferentiated state marker. To investigate the characterization of cochlear feeder cells, surface antigens were identified by flow cytometry.

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.
