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

Stem cells provide a new strategy for the treatment of cardiac diseases; however, their effectiveness in dilated cardiomyopathy (DCM) has not been investigated. In this study, cardiosphere-derived cells (CDCs) were isolated from infants (≤ 24 months) and identified by the cell surface markers CD105, CD90, CD117 and CD45, which is consistent with a previous report, although increased CD34 expression was observed. The molecular expression profile of CDCs from infants was determined by RNA sequencing and compared with adult CDCs, showing that infant CDCs have almost completely altered gene expression patterns compared with adult CDCs. The upregulated genes in infant CDCs are mainly related to the biological processes of cell morphogenesis and differentiation. The molecular profile of infant CDCs was characterized by lower expression of inflammatory cytokines and higher expression of stem cell markers and growth factors compared to adult CDCs. After intramyocardial administration of infant CDCs in the heart of DCM rats, we found that infant CDCs remained in the heart of DCM rats for at least 7 days, improved DCM-induced cardiac function impairment and protected the myocardium by elevating the left ventricular ejection fraction and fraction shortening. However, the effectiveness of transplanted CDCs was reversed later, as increased fibrosis formation instead of angiogenesis was observed. We concluded that infant CDCs, with higher expression of stem cell markers and growth factors, exhibit non-durable heart protection due to limited residence time in the heart of DCM animals, suggesting that multiple administrations of the CDCs or post-regulation after transplantation may be the key for cell therapy in the future.
