Deformability-augmented mesenchymal stem cells post-enucleation for efficient mRNA intervention of pulmonary fibrosis in rodent model.
Article in iScience, 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
Stem cell therapy has demonstrated significant therapeutic potential. However, the relatively large cellular diameter increases the likelihood of entrapment within capillaries, impeding the migration of stem cells to disease foci. We, herein, propose an enucleation strategy to enhance cell deformability, significantly improving vascular transit efficiency. Computational modeling, combined with experimental investigations using a microfluidic platform, revealed that increased cellular deformability, rather than a reduction in diameter, plays a greater role in facilitating cell transit, thereby challenging traditional perspectives on the cell mechanics. Observations of pulmonary vasculature using optical tissue-clearing and fluorescence micro-optical sectioning tomography confirmed the extensive distribution of enucleated cells and their reduced entrapment within fibrotic foci. Consequently, enucleated mesenchymal stem cells could efficiently deliver mRNAs to the fibrotic sites, significantly mitigating pulmonary fibrosis. Our findings provide new insights into the role of enucleation in facilitating cellular transit through constricted vasculature and the underlying mechanobiology of enhanced deformability.
