<i>Runx1</i> expression defines a subpopulation of displaced amacrine cells in the developing mouse retina
Bibliographic record
Abstract
AML1/Runx1 (Runx1) is a mammalian transcription factor that plays critical roles in regulating the differentiation of a number of different cell types. In the present study, we have utilized mice expressing beta-galactosidase (beta-gal) under the control of the Runx1 promoter to characterize the spatiotemporal expression pattern of Runx1 during retinogenesis. Expression of beta-gal was first detected at embryonic day 13.5 in post-mitotic cells located in the inner retina and overlapped with expression of the early amacrine and ganglion cell marker protein Islet1. During subsequent developmental stages, the number of beta-gal-positive cells increased in a central-to-peripheral gradient until late embryogenesis but then decreased in the early post-natal retina. beta-gal-positive cells were located primarily in the ganglion cell layer by late embryonic/early post-natal stages and were identified as a subpopulation of displaced amacrine cells by the continued expression of Islet1, as well as Pax6, and the coexpression of the amacrine cell subtype-specific markers choline acetyltransferase, calretinin and the 65-kDa isoform of glutamic acid decarboxylase. These findings identify Runx1 as a novel marker for a restricted amacrine cell subtype and suggest a role for this gene in regulating the post-mitotic development of these cells.

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.
