A multicellular star-shaped actin network underpins epithelial organization and connectivity.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Epithelial tissues withstand external stresses while maintaining structural stability. Bicellular junctions and the actomyosin network support epithelial integrity, packing and remodelling. While their role in development and disease are well studied, their synergistic impact on maintaining tissue organization remains unclear. Here, we identify a tissue-scale actomyosin network in adult murine intestinal villi, as well as in an ex vivo organoid-based epithelium model. This actomyosin network consists of repeated units of actin stars - radial actin structures at the base of hexagonal cells - linked via bicellular junctions into a multicellular array. Functionally, actin stars maintain epithelial morphological stability by preserving cell shape and packing. Laser ablation experiments support a modified vertex model, linking tension along actin star branches to epithelial arrangement. Additionally, actin stars act as basal locks, limiting protrusive activity, and hindering cell migration and tissue disruption. Together, these findings reveal the star-shaped supracellular actin network as a pivotal biomechanical system governing epithelial layer coordination.
