Abstract
There is presently great interest in using early embryonic tissues, particularly human tissue, for studies of protein and gene expression. Embryonic human tissue is very fragile, and delays often occur before it can be properly prepared for scientific study. Using chick embryos, we have studied the effects of delaying fixation or biochemical isolation on the preservation of cytological characteristics and biochemical molecules. Our study shows that by 60 min post-harvest, tissue morphology and immunofluorescence staining degrades, but the total mRNA profile remains stable. This study suggests that the time between removal of the tissue and fixation is critical to the results and that the critical time is much shorter for embryonic tissues than for more developed tissues. Our results have implications for all research where embryonic tissues are harvested but not processed immediately.

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
