Abstract
Osteochondral tissue engineering presents a significant challenge due to the intricate architecture of osteochondral units, necessitating the development of advanced biomaterials capable of directing the regeneration of spatially heterogeneous and structurally complex tissues. Here, a lignin dehydrogenated polymer (DHP), a promising lignin-derived biomaterial for cartilage repair, was subjected to phosphorylation to yield phosphorylated DHP (DHP-P) with the aim of enhancing synergistic osteochondral regeneration through coordinated modulation of cartilage and bone remodeling. Hydrogel scaffolds incorporating DHP-P were subsequently fabricated and demonstrated remarkable efficiency in restoring osteochondral defects via a synergistic cartilage-bone remodeling mechanism. Through the coordinated regeneration of articular cartilage and subchondral bone, we established that a single phosphorylated lignin derivative can simultaneously promote chondrogenesis and regulate subchondral bone remodeling. This work identifies lignin-based natural products as promising platforms for tissue engineering applications, providing a novel perspective for their high-value utilization in regenerative medicine.

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
