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

objectiveTo test the hypothesis that human embryonic stem cells (hESCs) can be guided to form new myocardium by transplantation into the normal or infarcted heart, and to assess the influence of hESC-derived cardiomyocytes (hESCMs) on cardiac function in a rat model of myocardial infarction (MI).

methodsUndifferentiated hESCs (0.5-1x10(6)), human embryoid bodies (hEBs) (4-8 days; 0.5-1x10(6)), 0.1 mm pieces of embryonic stem-derived beating myocardial tissue, and phosphate-buffered saline (control) were injected into the normal or infarcted myocardium of athymic nude rats (n = 58) by direct injection into the muscle or into preimplanted three-dimensional alginate scaffold. By 2-4 weeks after transplantation, heart sections were examined to detect the human cells and differentiation with fluorescent in situ hybridisation, using DNA probes specific for human sex chromosomes and HLA-DR or HLA-ABC immunostaining.

resultsMicroscopic examination showed transplanted human cells in the normal, and to a lesser extent in the infarcted myocardium (7/7 vs 2/6; p<0.05). The transplanted hESCs and hEBs rarely created new vessels and did not form new myocardium. Transplantation of hESCM tissue into normal heart produced islands of disorganised myofibres, fibrosis and, in a single case, a teratoma. However, transplantation of hESCMs into the infarcted myocardium did prevent post-MI dysfunction and scar thinning.

conclusionsUndifferentiated hESCs and hEBs are not directed to form new myocardium after transplantation into normal or infarcted heart and may create teratoma. Nevertheless, this study shows that hESC-derived cardiomyocyte transplantation can attenuate post-MI scar thinning and left ventricular dysfunction.
