Isolation of Epidermal Keratinocytes from Human Skin: The Scratch-Wound Assay for the Assessment of Epidermal Keratinocyte Migration.
Article in Methods in molecular biology (Clifton, N.J.), 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
The migration of epidermal keratinocytes is the basis for skin re-epithelialization during wound healing. The in vitro scratch-wound assay using monolayers of primary human epidermal keratinocytes is a straightforward and effective method to assess their migratory capacity. The mechanical scratch of a confluent monolayer directly disrupts the adhesion of the keratinocytes to one another and to the underlying matrix, resembling the physical trauma of a wound in an in vitro assay. The keratinocytes will undergo an epithelial-to-mesenchymal transition, which will confer an ability to migrate toward each other to cover the gap by restructuring cell-cell and cell-extracellular matrix connections. However, a good scratch-wound method and protocol to ensure scratch reproducibility is essential, particularly when using primary cell cultures where donor variability may also impact results.
