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

rationaleTransgenic Notch reporter mice express enhanced green fluorescent protein in cells with C-promoter binding factor-1 response element transcriptional activity (CBF1-RE(x)₄-EGFP), providing a unique and powerful tool for identifying and isolating "Notch-activated" progenitors.

objectiveWe asked whether, as in other tissues of this mouse, EGFP localized and functionally tagged adult cardiac tissue progenitors, and, if so, whether this cell-based signal could serve as a quantitative and qualitative biosensor of the injury repair response of the heart. METHODS AND

resultsIn addition to scattered endothelial and interstitial cells, Notch-activated (EGFP(+)) cells unexpectedly richly populated the adult epicardium. We used fluorescence-activated cell sorting to isolate EGFP(+) cells and excluded hematopoietic (CD45(+)) and endothelial (CD31(+)) subsets. We analyzed EGFP(+)/CD45⁻/CD31⁻ cells, a small (<2%) but distinct subpopulation, by gene expression profiling and functional analyses. We called this mixed cell pool, which had dual multipotent stromal cell and epicardial lineage signatures, Notch-activated epicardial-derived cells (NECs). Myocardial infarction and thoracic aortic banding amplified the NEC pool, increasing fibroblast differentiation. Validating the functional vitality of clonal NEC lines, serum growth factors triggered epithelial-mesenchymal transition and the immobilized Notch ligand Delta-like 1-activated downstream target genes. Moreover, cardiomyocyte coculture and engraftment in NOD-SCID (nonobese diabetic-severe combined immunodeficiency) mouse myocardium increased cardiac gene expression in NECs.

conclusionsA dynamic Notch injury response activates adult epicardium, producing a multipotent cell population that contributes to fibrosis repair.
