ECM-Preserving Decellularization of Dermis via Subtle Cell Membrane Disruption Induced by Subcritical Dimethyl Ether.
Article in ACS omega, 2025. 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
Decellularized tissues are used as biomaterials for transplantation. Many decellularized tissues in clinical applications are prepared using surfactants; however, we have developed a new decellularization method that uses subcritical dimethyl ether (DME) instead of surfactants. Subcritical DME perfusion is usually used for lipid extraction; therefore, by perfusing tissues with subcritical DME, phospholipid cell membranes may be destroyed. DME vaporizes at room temperature and pressure, therefore, it is expected that it will not remain in the decellularized tissues and will not be toxic. In this study, subcritical DME was perfused into the porcine dermis, and the sample was subjected to DNA degradation to produce a subcritical DME-decellularized dermis. The subcritical DME-decellularized dermis showed good cell response in vitro and in vivo. In addition, we investigated the mechanism of the subcritical DME decellularization method and found that surfactants dissolve the entire cell and almost remove it; however, subcritical DME causes minor damage to the cell membrane and removes the cell nucleus through DNase treatment while leaving some of the cell membrane intact. These results suggest that subcritical DME-decellularized dermis is nontoxic and has the potential to develop highly functional decellularized tissues, such as extracellular vesicles, unlike decellularized dermis prepared with surfactants.
