Unraveling the matrisome signatures of quiescent and activated muscle stem cells.
Article in Stem cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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 extracellular matrix (ECM) forms a dynamic microenvironment, known as the "niche," that influences muscle stem cell (MuSC) behavior. Its composition and topology remain underexplored. Using bioinformatics analysis of publicly available transcriptomic data, we profiled the matrisome of skeletal muscle-resident cells and identified quiescent MuSCs as key ECM producers. Their matrisome includes novel markers such as the basement membrane zone genes Col19a1 and Lama3, ECM assembly regulators Thsd4 and Aebp1, and notably, matrisome genes linked to neurogenesis. Light-sheet immunofluorescence microscopy of selected ECM components in isolated murine myofiber bundles revealed niche-specific ECM components associated with MuSCs. Upon activation, these cells shifted their gene expression, downregulating niche-associated ECM genes while upregulating those involved in basement membrane disruption and cell motility. These findings identify distinct matrisome signatures in quiescent and activated MuSCs, emphasizing the critical role of ECM in locally regulating MuSC states and highlighting its therapeutic potential for muscle regeneration.
