Epigenetic regulation and mechanobiological adaptation in tenocytes during maturation.
Article in APL bioengineering, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Tendons are essential for musculoskeletal function, facilitating movement by transmitting forces from muscles to bones. However, aging alters the tendon microenvironment, disrupting the delicate interactions between tenocytes and the extracellular matrix (ECM), contributing to tissue degeneration. While prior studies have characterized the mechanical and structural changes in tendons during maturation, the epigenetic regulation of tenocyte function during aging remains poorly understood. Here, we investigate age-dependent mechanobiological and epigenetic changes in murine tenocytes. Our findings demonstrate that mature tenocytes generate higher traction forces and migrate faster. Furthermore, we reveal increased chromatin condensation in mature tenocytes, accompanied by elevated levels of the repressive histone mark H3K27me3 and reduced levels of the activating mark H3K4me3. Chromatin immunoprecipitation sequencing indicates that these histone modifications regulate genes associated with cellular contractility, ECM production, and mechanotransduction, highlighting the critical role of epigenetic mechanisms in governing tenocyte function. These findings suggest that age-related epigenetic changes may contribute to both the maintenance of tissue homeostasis and the suppression of degenerative diseases in tendons, providing new avenues for therapeutic strategies aimed at restoring tenocyte function and enhancing tendon regeneration.
