The N-glycome regulates the endothelial-to-hematopoietic transition
Bibliographic record
Abstract
Sugar code regulates blood stem cells During embryonic development, blood stem cells are derived from vascular endothelial cells that line the walls of developing arteries. The transition from endothelial cells to blood stem cells is highly regulated and restricted to a small portion of endothelial cells during a brief period of time. The mechanisms regulating this transition are also poorly understood. Kasper et al. found that microRNA-223 intrinsically restrains the vascular hematopoietic transition by regulating N-glycan biosynthesis to restrict hematopoietic stem and progenitor cell production and differentiation. Genetics or chemicals could be used to alter the sugar code and change the efficiency of blood production in embryos. Thus, genetically or pharmacologically altering N-glycan biosynthesis in endothelial cells could improve the efficiency of the production of blood stem cells, which could then be used to treat blood diseases such as leukemia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
