Abstract
Small diameter hydroxyethyl methacrylate-methyl methacrylate (HEMA-MMA; 75% HEMA) microcapsules containing an aggregate of viable rat hepatoma H4IIEC3 cells, after implantation into an omental pouch in Wistar rats, contained viable cells at 7 days but not 14 days. A similar transplantation of microencapsulated aggregates of human hepatoma HepG2 cells did not result in viable cells even at 7 days. The loss of viability was attributed to the tissue reaction, because both encapsulated cell types remained viable in vitro. However, it is not clear if the cells lost their viability in vivo, leading to the aggressive tissue reaction or if the latter caused the cells to starve or otherwise die. The tissue reactions to microcapsules containing rat or human hepatoma cells at day 1 was one cell layer thick and avascular. At later times, tissue reactions were comprised of three regions: macrophages, fibroblasts, and some foreign body giant cells apposed to the polymer membrane, a dense region of fibroblasts and collagen, and a region of vascularized granulation tissue. Prompt vascularization of the tissue reactions occurred after 4 days and was maintained for up to 14 days. Even at 14 days, immune cells were observed, suggesting a continued immune response toward antigens shed from the encapsulated cells.

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
