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

Culture-expanded mesenchymal stromal cells (MSCs) are capable of fostering tissue regeneration after transplantation. However, the behavior and physiological role of endogenous MSCs in distal organ repair remain undetermined. In this study, a suite of genetic tools is generated to distinguish MSCs between tissues, and to map their fate in local, proximate, and distal organ repair. By single-cell RNA-sequencing, it is found that the transcriptomic profiles of most non-bone marrow-derived mesenchymal stromal cells (nonBM-MSCs) exhibited high similarities, yet differed from that of bone marrow-derived mesenchymal stromal cells (BM-MSCs), especially in their less abundant secretome. Fate-mapping experiments demonstrated that BM-MSCs do not contribute to the formation of myofibroblasts during fibrosis or cancer-associated fibroblasts (CAFs) during tumorigenesis. In contrast, MSCs from proximate tissues actively migrated to the site of bone fracture, where they contributed to the formation of fibrocartilaginous soft callus. During injury-associated inflammation, local MSCs modulated the polarization of tissue-resident macrophages, whereas BM-MSCs mobilized monocytes to the site of inflammation. Conditional deletion of Ccl2 in BM-MSCs, but not in colon-resident MSCs, ameliorated colon inflammation and restored body weight after colitis. Thus, injury repair is orchestrated by MSCs from multiple sources, with local, proximate, and distal MSCs acting through different mechanisms.
