Wnt signaling regulates passive cell competition in the retina by inducing differential cell adhesion.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Self-assortment of progenitor cells is critical for establishing distinct tissue identities during development, including segregation of the optic cup into the neural retina (NR) and ciliary margin (CM). Although Wnt signaling is required for CM specification, here we show that genetic ablation of β-catenin in the peripheral optic cup does not prevent formation of the CM-derived ciliary body and iris in adult mice. Mosaic analysis reveals that β-catenin-deficient cells are excluded from the CM due to a Wnt-dependent switch from P- to N-cadherin. This cadherin switch drives segregation of otherwise similar cells into distinct clusters, as supported by theoretical modeling and experimental manipulation of cadherin interactions. Consequently, wild-type cells are preferentially retained in the CM niche to support ciliary body formation, a process reversed by deletion of P- and N-cadherins. Together, these findings demonstrate that Wnt signaling can define tissue niches through passive cell competition.
