Single-cell omics uncover gene dynamics shaping embryonic and extra embryonic lineages in pig blastocysts.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Late blastocyst development before implantation is a unique feature of ungulates, during which the epiblast proliferates and maintains pluripotency while extra-embryonic tissues expand dramatically, elongating to several tens of centimeters. The mechanisms coordinating these processes are not well understood. We performed single-cell omics profiling of porcine blastocysts from the hatched stage (E7) through early (E9) and late ovoid stages (E11). From 15,370 cells, we identified distinct embryonic and extra-embryonic populations with characteristic chromatin accessibility profiles. We reconstructed gene regulatory networks using enhancer-based eRegulons and validated them through motif occupancy analysis. Extra-embryonic tissues showed strong shifts in gene regulatory module activity at the onset of elongation, reflecting major transitions in morphogenesis and differentiation and the activation of pathways linked to cell morphology, proliferation, metabolism, trafficking, and biomolecule transport. In contrast, epiblast cells retained a stable transcriptional and regulatory identity from day 7 to day 11, immediately preceding the onset of gastrulation.
