1 · What the graph read from 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.

2 · The registry

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

Fibroblasts display complex functions linked to distinct gene expression profiles. These profiles influence matrix production, cell communication, and tissue development and repair. Thrombospondin-2 (TSP2), produced by fibroblasts, is a potent angiogenesis inhibitor and negatively associated with tissue repair. Single-cell RNA sequencing (scRNA-seq) on WT and TSP2 KO skin fibroblasts demonstrate distinct cell heterogeneity. Specifically, we found an enrichment of Sox10 + multipotent progenitor cells, identified as Schwann precursor cells, in TSP2 KO fibroblasts, while fibrosis-related subpopulations decreased. Immunostaining of mouse back skin wounds and cells validated the increase of this Sox10 + population. Furthermore, in silico analysis suggested enhanced PDGF-β-mediated pro-survival and inhibited BMP4-mediated differentiation signaling pathways. These molecular and functional alterations likely contribute to improved healing and increased neurogenesis in TSP2 KO wounds. Overall, our findings describe the heterogeneity of dermal fibroblasts (DFs) and identify pro-regenerative features of TSP2 KO fibroblasts.
