Abstract
In the developing limb, dorsal-ventral patterning is controlled by the transcription factor LMX1B, expressed in the dorsal mesenchyme. Loss of Lmx1b function in mice or humans results in the loss of dorsal limb structures and Nail-Patella syndrome, but the effectors through which LMX1B controls limb patterning are virtually unknown. Using microarrays to analyze the differential expression of mRNAs in wild-type vs. Lmx1b(-/-) limb buds, we have identified hundreds of genes as putative LMX1B targets. Analysis of a subset of these candidates by in situ mRNA localization has identified eight genes previously unknown to require Lmx1b for their dorsal-ventral restriction of expression in the limb. Furthermore, our results suggest that LMX1B controls different targets along the proximal-distal axis of the limb, and suggest the existence of a dorsal proximal limb region that is rich in mRNAs requiring Lmx1b for their expression.

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 it
