Differential Gene Expression in the Uterus and Blastocyst During the Reactivation of Embryo Development in a Model of Delayed Implantation
Bibliographic record
Abstract
Delayed implantation, a reversible arrest in embryo development while the embryo is at the blastocyst stage, provides an interesting window for observation of the preparation for implantation on both the embryonic and maternal sides. The American mink (Mustela vison) is a species in which delayed implantation is a normal aspect of embryo development as it consistently occurs at each breeding season. We used a transcriptome-wide approach to screen global gene expression and to identify new key genes expressed in the uterus and in the endometrium at the resumption of the embryo development, after delayed implantation. By using the suppressive subtractive hybridization (SSH) technique, two libraries of differentially expressed cDNAs, one at the uterine level and a second one at the blastocyst level, were successfully generated. Candidate genes from those two libraries were selected and their differentially expressed pattern of expression between reactivation and delayed implantation was investigated by real-time PCR and immunolocalization.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
