Abstract
Extensive effort has been made to develop a three-dimensional (3D) system for the culture of pluripotent stem cells in human and model animals, which yields lots of benefits for monitoring cell-to-cell or cell-to-environment interaction and for suggesting alternative materials for clinical cases. Initial study using animal model moved toward supporting embryonic stem cells (ESCs) self-renewal in a synthetic scaffold conjugated with suitable peptide motifs. As results, the feeder-free, 3D acellular niche consisting of vinyl sulfone (VS)-functionalized polyethylene glycol (PEG)-based hydrogel binding with extracellular matrix analogs could support ESC self-renewal, but main stemness signals were switched in the 3D environment. We employed this PEG-based hydrogel for 3D culture of human ESCs and further adjustment of hydrogel constituent made it possible to support self-renewal of three ESC lines. In this study, we examined transcriptional and translational activity of integrin heterodimers for optimizing the 3D system by using peptide motifs and subsequently elucidated that transcription and translation of integrin α 5β 1, α 6β 1 and αVβ 5 were stronger than other heterodimers in a referenced human ESC line.

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
