Multiomic profiling reveals that prostaglandin E2 reverses aged muscle stem cell dysfunction, leading to increased regeneration and strength.
Article in Cell stem cell, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 papers.
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
Repair of muscle damage declines with age due to the accumulation of dysfunctional muscle stem cells (MuSCs). Here, we uncover that aged MuSCs have blunted prostaglandin E2 (PGE2)-EP4 receptor signaling, which causes precocious commitment and mitotic catastrophe. Treatment with PGE2 alters chromatin accessibility and overcomes the dysfunctional aged MuSC fate trajectory, increasing viability and triggering cell cycle re-entry. We employ neural network models to learn the complex logic of transcription factors driving the change in accessibility. After PGE2 treatment, we detect increased transcription factor binding at sites with CRE and E-box motifs and reduced binding at sites with AP1 motifs, overcoming the changes that occur with age. We find that short-term exposure of aged MuSCs to PGE2 augments their long-term regenerative capacity upon transplantation. Strikingly, PGE2 injections following myotoxin- or exercise-induced injury overcome the aged niche, leading to enhanced regenerative function of endogenous tissue-resident MuSCs and an increase in strength.
