Abstract
CD34 is a cell-surface sialomucin widely used for hematopoietic stem cell purification and as a marker of most vascular endothelial cells, including those of capillaries in the majority of tissues. Surprisingly, despite extensive research, the function of this sialomucin has remained elusive, with proposed roles ranging from enhancing proliferation or inhibiting differentiation to acting as a proadhesive L-selectin ligand. Here, we review our recent studies, which suggest that CD34 does, indeed, play a role in leukocyte and HSC trafficking, but that this is through its action as a regulated blocker of cell adhesion and enhancer of migration.

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
