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

Human lungs bear their own reservoir of endogenous mesenchymal stem cells (MSCs). Although described as located perivascular, the cellular identity of primary lung MSCs remains elusive. Here we investigated the vascular nature of lung-resident MSCs (LR-MSCs) using healthy human lung tissue. LR-MSCs predominately reside within the vascular stem cell niche, the so-called vasculogenic zone of adult lung arteries. Primary LR-MSCs isolated from normal human lung tissue showed typical MSC characteristics in vitro and were phenotypically and functionally indistinguishable from MSCs derived from the vascular wall of adult human blood vessels (VW-MSCs). Moreover, LR-MSCs expressed the VW-MSC-specific HOX code a characteristic to discriminate VW-MSCs from phenotypical similar cells. Thus, LR-MSC should be considered as VW-MSCs. Immunofluorescent analyses of non-small lung cancer (NSCLC) specimen further confirmed the vascular adventitia as stem cell niche for LR-MSCs, and revealed their mobilization and activation in NSCLC progression. These findings have implications for understanding the role of MSC in normal lung physiology and pulmonary diseases, as well as for the rational design of additional therapeutic approaches.
