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

To date, a large number of reports have described reprogramming many somatic cell types into induced pluripotent stem (iPS) cells, using different numbers of transcription factors and devising alternate methods of introducing the transcription factor genes or proteins into the somatic cells. Here, we describe a method using bacteriophage ΦC31 integrase to reprogram mouse embryonic fibroblasts and human amniotic fluid cells into iPS cells. These iPS cells showed morphology, surface antigens, gene expression, and epigenetic states similar to ES cells and formed teratomas with three germ layers in nonobese diabetic/severely compromised immunodeficient mice. Importantly, these iPS cells have only a single integration site in each cell line. The locations of integration favor the intergenic regions, and their distances from the adjacent genes extended from several hundred to >1 million bp. The effect of the insertion on the expression of these genes can be studied by RT-PCR. No insertion into microRNA gene loci was detected. Hence, it is possible to select cells in which adjacent gene functions are not affected, or the inserts can be removed if necessary. We conclude that phage integrase-mediated site-specific recombination can produce iPS cells that have undisturbed endogenous gene function and could be safe for future human therapeutic application.
