Abstract
Endothelial-to-mesenchymal transition (EndoMT) is an instrumental step in the development of valves in the embryonic heart. This process is driven by activation of transforming growth factor-β (TGF-β) signaling and is characterized by the loss of endothelial and gain of mesenchymal phenotype, and by delamination of cells from the surface into the underlying endocardial cushion matrix. The endothelial cells (ECs) overlying the cushions are typically exposed to high blood flow and concomitant shear stress and do not have a primary cilium. Here, we show that shear stress activates TGF-β-Alk5 signaling in ECs, which is necessary for EndoMT in the cushions. Moreover, we show that the absence of a primary cilium is critically important for this transition process.

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
