In Vitro Assessment of Osteoblast Behavior in Craniosynostosis
Bibliographic record
Abstract
Introduction: The objective of this study is to investigate the role of osteoblasts in the pathophysiology of premature suture fusion in infants.\nMethods: Bone and periosteal tissue from fused and patent cranial sutures and adjacent bone were harvested from infants undergoing surgery for craniosynostosis and used to develop primary osteoblast cell cultures. Dural tissue was obtained from neurosurgical procedures in order to generate an osteoblast-dural co-culture. Osteoblast proliferation, differentiation, mineralization, protein expression (Noggin, BMP3 and Runx2) and response to exogenous FGF2 stimulation were assessed.\nResults: Cell cultures demonstrated significant (p<0.05) regional variations in osteoblast proliferation, differentiation markers and in vitro bone nodule formation. The expression of anti-osteogenic molecules (Noggin and BMP3) was decreased in osteoblasts from fused suture regions.\t\nConclusion: The creation of a pro-osteogenic environment through the decreased expression of anti-osteogenic signalling molecules and increased expression of osteogenic factors may be responsible for premature suture fusion in infants.

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.
