Promotion of angiogenesis and suppression of inflammatory response in skin wound healing using exosome-loaded collagen sponge.
Article in Frontiers in immunology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Effectively promoting skin wound healing remains a significant challenge in the medical field. Although stem cell-derived exosomes show potential in tissue regeneration, their local delivery and sustained release face challenges. To address these issues, we developed a collagen sponge based on type I and recombinant humanized type III collagen. Our study confirmed that exosomes were successfully loaded onto the sponge (sponge-Exo) and the sponge-Exo gradually released exosomes into the local milieu. The sponge-Exo played a crucial role in promoting the transition of macrophages from an inflammatory M1 phenotype to a regenerative M2 phenotype. Moreover, it enhanced the migration and proliferation of HDFs and promoted angiogenesis in HUVECs. Additionally, our findings revealed that the sponge-Exo accelerated wound healing by suppressing inflammatory response and stimulating angiogenesis in a rat full-thickness skin wounds model. Next generation sequencing (NGS) was used to explore the underlying mechanism of wound healing, and the results showed that the miRNAs (hsa-miR-21-5p and hsa-miR-29a-5p) associated with wound healing in exosomes were significantly up-regulated. These results highlight the remarkable effects of sponge-Exo on macrophage transformation, cell migration, proliferation and angiogenesis, which provide a potential prospect for the application in the field of skin wound healing.
