BMSC-derived exosomes improve rheumatoid arthritis by regulating Th17 cell differentiation through targeting PRDM1.
Article in Regenerative medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundRheumatoid arthritis (RA) is categorized as an autoimmune condition. Bone marrow-derived mesenchymal stromal cell (BMSC) derived exosome (BMSC-Exo) exert vital character in RA. We aimed to investigate the regulatory mechanism of BMSC-Exo in alleviating RA.
methodsBMSC was isolated from mouse bone marrow. Collagen-induced arthritis (CIA) was induced by injecting bovine type II collagen and complete Freund's adjuvant. Arthritis score, incidence, and withdrawal threshold were assessed. Hematoxylin-eosin staining was used to observe knee joint damage. CD4
resultsBMSC-Exo injection reduced arthritis score and incidence of arthritis, and elevated the withdrawal threshold of CIA mice. BMSC-Exo also alleviated knee damage in CIA mice and reduced the Th17 proportion. BMSC-Exo down-regulated inflammatory cytokine levels, as well as caspase-1 activity. BMSC-Exo up-regulated PR Domain Zinc Finger Protein 1 (PRDM1) levels. PRDM1 knockdown in BMSC down-regulated PRDM1 expression in Exo but did not affect up-regulated PRDM1 expression in CD4
conclusionsBMSC-Exo improved RA by promoting PRDM1 expression in CD4
