1q gain bypasses the selective barrier against aneuploidy in RPE differentiation via wild-type co-culture rescue.
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 3 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
Human pluripotent stem cells (hPSC) are increasingly used in clinical trials, with retinal pigment epithelium (RPE) being among the most transplanted cell types. However, hPSC frequently acquire chromosomal abnormalities, whose impact on differentiation and transplant safety is incompletely understood. In this work, we investigate how aneuploidy influences the progression of hPSC through undirected RPE differentiation. Large-scale omics analysis of genetically normal hPSC cultures reveals pervasive low-grade mosaicism, with 3-6% of cells carrying different aneuploidies. During undirected differentiation, all aneuploid cells are lost except those with a gain of chromosome arm 1q. These cells differentiate efficiently only when co-cultured with wild-type cells, which promote neural differentiation through paracrine signals that 1q-gain cells are uniquely receptive to. This interaction enables 1q-gain cells not only to persist but to eventually dominate the culture, owing to their competitive advantage.
