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 embryonic stem cells (hESCs), due to their pluripotent nature, represent a particularly relevant model system to study the relationship between the replication program and differentiation state. Here, we define the basic properties of the replication program in hESCs and compare them to the programs of hESC-derived multipotent cells (neural rosette cells) and primary differentiated cells (microvascular endothelial cells [MECs]). We characterized three genomic loci: two pluripotency regulatory genes, POU5F1 (OCT4) and NANOG, and the IGH locus, a locus that is transcriptionally active specifically in B-lineage cells. We applied a high-resolution approach to capture images of individual replicated DNA molecules. We demonstrate that for the loci studied, several basic properties of replication, including the average speed of replication forks and the average density of initiation sites, were conserved among the cells analyzed. We also demonstrate, for the first time, the presence of initiation zones in hESCs. However, significant differences were evident in other aspects of replication for the DNA segment containing the POU5F1 gene. Specifically, the locations of centers of initiation zones and the direction of replication fork progression through the POU5F1 gene were conserved in two independent hESC lines but were different in hESC-derived multipotent cells and MECs. Thus, our data identify features of the replication program characteristic of hESCs and define specific changes in replication during hESC differentiation.
