Abstract

fetched live from OpenAlex

Collagen is a naturally occurring structural protein, highly conserved across species. Conventionally, tissue engineering aims to convert cell-seeded constructs into a tissue-like architecture with biomimetic function. However, cell-mediated remodelling of biomaterial scaffolds in vitro has proved to be slow, costly and difficult to control. We have recently developed a novel process for ultra-rapid engineering of tissue-like constructs without the need for cell-based remodelling. Using plastic compression of type I collagen gels, the densities of collagen and cells together with mechanical properties can be brought controllably to near-tissue levels in minutes rather than weeks/months. We have now implanted these constructs in a test site across intercostal spaces in a rabbit model designed to provide cyclical tensile loading in vivo, to test their integration, cell ingrowth and angiogenic response over 5 weeks. Post-implanted constructs were recovered and tested for host vascularization, inflammatory response and mechanical integrity.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
