Livestock Blastoids: In Vitro Blastocyst Models for Embryogenesis and Reproductive Technologies.
Review in Reproduction in domestic animals = Zuchthygiene, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Understanding early embryogenesis in livestock remains a persistent bottleneck in both reproductive biology and animal breeding. Work in domestic species has long been limited by restricted access to embryos, ethical considerations, and the complexity of peri-implantation development, making mechanistic studies difficult. Recent advances in stem cell biology are beginning to shift this. Blastocyst-like structures, or blastoids, now offer a practical way to model early development in vitro. Blastoids capture key features of natural blastocysts, including overall structure, lineage composition, and gene expression patterns, while being far more accessible experimentally. In livestock species, especially cattle and pigs, blastoid models are starting to gain traction. Livestock blastoids provide a tractable system to study lineage specification, epiblast-extraembryonic interactions, and early conceptus development. They also open the door to improving assisted reproductive technologies by enabling controlled, scalable experimentation that is not feasible with embryos alone. In this review, we summarize recent advances in the generation of livestock blastoids and discuss how these systems can be used to study early development across livestock species and to inform next-generation reproductive technologies. We highlight current limitations and outline key challenges ahead, including how blastoid models can be combined with genome editing, stem cell engineering and related embryo-based approaches to improve reproductive efficiency in domestic animals.
