Abstract
The role of c-myc has been well-studied in gene regulation and oncogenesis but remains elusive in murine development from midgestation. We determined c-myc function during kidney development, organogenesis, and homeostasis by conditional loss of c-myc induced at two distinct phases of nephrogenesis, embryonic day (e) 11.5 and e17.5. Deletion of c-myc in early metanephric mesenchyme (e11.5) led to renal hypoplasia from e15.5 to e17.5 that was sustained until adulthood (range, 20-25%) and, hence, reproduced the human pathologic condition of renal hypoplasia. This phenotype resulted from depletion of c-myc-positive cells in cap mesenchyme, causing a approximately 35% marked decrease of Six2- and Cited1-stem/progenitor population and of proliferation that likely impaired self-renewal. By contrast, c-myc loss from e17.5 onward had no impact on late renal differentiation/maturation and/or homeostasis, providing evidence that c-myc is dispensable during these phases. This study identified c-myc as a modulator of renal organogenesis through regulation of stem/progenitor cell population.

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
