Comparative Single-Cell Analysis Reveals Tendon Progenitor Dysfunction by Age-Associated Oxidative Stress and Its Restoration by Antioxidant Treatments.
Article in Journal of cellular physiology, 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
Impaired healing of adult tendons with fibrosis remains clinical challenges while neonatal tendons have full functional restoration. However, age-associated cellular and molecular changes in tendon cells and tendon stem/progenitor cells (TSPCs) remain unknown. Here, comparative single cell transcriptomics of early postnatal (2 weeks old) and adult (20 weeks old) mouse tendons revealed that adult tendons have reduced number of TSPCs, decreased gene expression in tendon and cartilage development, and a greater population of fibro-tenogenic cells. Notably, adult TSPCs and tenocytes exhibit increased expression of immune-response and oxidative-stress genes with higher EGFR but decreased IGF signaling. Adult tendon cells show increased levels of intracellular reactive oxygen species (ROS) in vivo. In contrast, antioxidant treatment of adult tendons significantly reduces intracellular ROS of TSPCs and improves tendon strength in vivo. Hence, these findings suggest that increased inflammation and ROS during tendon aging deteriorates tendon function and regeneration that can be mitigated by antioxidant treatment.
