Article in Combinatorial chemistry & high throughput screening, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundMany studies have documented the protective effects of regulating macrophage M1/M2 polarization in inflammatory diseases characterized by their imbalance state. In pathological diseases associated with inflammation, mesenchymal stem cells (MSCs) regulate macrophages, thereby having anti-inflammatory and tissue regenerative effects. Exosomes have been suggested as an alternative mechanism that underlies the paracrine function of MSCs. Thus, this study explored the anti-inflammatory impact of human umbilical cord MSCssecreted exosomes (hucMSCs-EX) by influencing macrophage polarization in normal and inflammatory environments
methodsIn this study, hucMSCs-conditioned medium (hucMSCs-CM) and hucMSCs- EX were used to treat RAW264.7 macrophages with or without LPS. The expressions of
resultsThe inhibition of LPS-induced inflammatory polarization by hucMSCs-EX or hucMSCs- CM led to increases in IL-10 and arginase (Arg) levels and decreases in those of IL-6 and TNF-α. Moreover, hucMSCs-EX enhanced the CD206 expression in RAW264.7 cells and accelerated the propagation and migration of LPS-induced cells. The suppressive impact of hucMSCs-EX on the LPS-induced phenotypic polarization of M1 macrophages was linked with the reduction of NF-κB signaling. They stimulated the transition of M2 macrophages by enhancing the activity of STAT3 in RAW264.7 cells.
conclusionThis study indicated that hucMSCs-EX enhances the macrophage transition into the M2 phenotype by inhibiting the NF-κB p65 axis and stimulating that of STAT3.
