Planar neural organoids as an advanced in vitro model to study patient-derived melanoma metastasis.
Article in Scientific reports, 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
Metastasis, which occurs when cancer cells spread from their original site in the body to other organs - is the leading cause of death in cancer patients. Conventional two-dimensional (2D) cell cultures along with orthotopic animal models are widely used to study and develop therapeutics for metastatic cancers. However, 2D cell cultures do not accurately reflect the physiology of real tissues, and the results obtained from the orthotopic animal models cannot always be applied to humans due to the interspecies differences. The recent emergence of human organoid models provides unique opportunities to study the complex cellular interactions in a near-physiological 3D environment. In this study, we have engineered an in vitro melanoma metastasis model using patient-derived melanoma cells and human-induced pluripotent stem cells (iPSCs)-derived planar neural organoids (PNOs). We investigated metastatic cancer processes such as the growth of melanoma cells, and evaluated the effects of anti-cancer drug treatment on it. Our results demonstrated that the 3D PNO system served as a more effective in vitro model than conventional 2D cultures to study melanoma brain metastases, and this PNO system can also be used to model other types of poorly understood metastatic cancers under physiological environments.
