Dynamic Remodeling of Mechano-Sensing Complexes in Suspended Fibroblast Cell-Sheets Under External Mechanical Stimulus.
Article in Biotechnology and bioengineering, 2025. 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
Freestanding cell-sheets are valuable bio-materials for use in regenerative medicine and tissue engineering. Because cell-sheets experience various mechanical stimulations during handling, it is important to understand the responses of cells to these stimulations. Here, we demonstrate changes in the localization of various proteins during the stretching of fibroblast cell-sheets. These proteins are known to be involved in mechano-sensing. Upon stretching, actin filaments appear parallel to the stretching direction. At cell-cell junctions, β-catenin forms clusters that co-localize with accumulated vinculin and zyxin as well as the actin filaments. The p130 Crk-associated substrate, known to be present in focal adhesions, is also recruited to these clusters and phosphorylated. Our results suggest that mechano-sensing machinery is formed at cell-cell junctions when the cell-sheets are stretched.
