<i>Sox15</i> is a novel retinal developmental gene that promotes cone photoreceptor differentiation through inhibition of alternative rod photoreceptor fates
Bibliographic record
Abstract
Abstract The type of cell fate decisions a progenitor can make in the developing nervous system are dependent on a combination of cell intrinsic gene expression programs and cell extrinsic signaling molecules that influence expression programs. Moreover, both the progenitor’s spatial location in the tissue and time at which it exists during development can, to varying degrees, influence the competency of differentiation. Here, we use the developing mouse retina to understand how signaling factors in the retinal niche can influence a progenitor to become unipotentially-restricted to differentiate into cone photoreceptors, and how this competency changes over the course of retinal development. We show that the secreted inhibitory protein COCO causes progenitors to become cone-restricted, and that the competency for this restricted differentiation is maintained throughout retinal development. Using RNA-sequencing, we identify the transcription factor Sox15 as a potential novel marker of restricted progenitors in the developing retina, and that it acts in response to COCO’s effects. Knockdown experiments indicate that this novel retinal transcription factor promotes cone differentiation by inhibiting differentiation into alternative photoreceptor types.

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.
