Skin Immuno-CometChip in 3D vs. 2D Cultures to Screen Topical Toxins and Skin-Specific Cytochrome Inducers.
Article in Genes, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The targets of topical genotoxic agents are basal and stem cells of the skin. These cells may misrepair DNA lesions, resulting in deleterious mutations of tumor suppressors or oncogenes. However, the genotoxicity of many compounds has not as yet been determined and needs to be tested using a relevant skin model. To this end, we designed a new high-throughput assay for the detection of agents that create DNA damage in epidermal stem and basal cells and used it to test known DNA-damaging agents. We utilized either 2D epidermal cells or 3D skin equivalents and topically exposed them to different compounds. The Skin Immuno-CometChip assay uses arrays of microwells formed in a collagen/agarose mixture to capture single basal cells in each microwell by virtue of collagen binding to α2β1 integrin, which is present only on basal and stem cells. The presence of β1 integrin was verified by immunofluorescent labeling cells that were then subjected to an electrical field, allowing for the migration of nicked DNA out of the nucleoid in alkali, with the resulting DNA comets stained and imaged. Furthermore, using improved comet detection software allowed for the automated and rapid quantification of DNA damage. Our study indicates that we can accurately predict genotoxicity by using 3D skin cultures, as well as keratinocytes grown in 2D monolayers.
