Engineering Organized Epithelium using Nanogrooved Topography in a Gelatin Hydrogel
Bibliographic record
Abstract
Tracheal epithelium is organized along two axes: apicobasal, seen through apical ciliogenesis, and planar seen through organized ciliary beating, which moves mucus out of the airway. Diseased patients with affected ciliary motility have serious chronic respiratory infections. The standard method to construct epithelium is through air liquid interface culture which creates apicobasal polarization, not planar organization. Nanogrooved surface topography created in diffusible substrates for use in air liquid interface culture will induce planar organization of the cytoskeleton.\nWe have created a nanogrooved gelatin device which allows basal nutrient diffusion. Multiple epithelial cells have been found to align in the direction of the nanogrooves in both sparse and confluent conditions. This device is also congruent with ALI culture as seen through formation of tight junctions and ciliogenesis. Thus, we have created nanogrooved surface topography in a diffusible substrate that induces planar alignment of epithelial cells and cytoskeleton.

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.
