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

In mice and humans, it has been shown that embryonic and adult fibroblasts can be reprogrammed into pluripotency by introducing 4 transcription factors, Oct3/4, Klf4, Sox2, and c-Myc (OKSM). Here, we report the derivation of induced pluripotent stem cells (iPSCs) from adult canine fibroblasts by retroviral OKSM transduction. The isolated canine iPSCs (ciPSCs) were expanded in 3 different culture media [fibroblast growth factor 2 (FGF2), leukemia inhibitory factor (LIF), or FGF2 plus LIF]. Cells cultured in both FGF2 and LIF expressed pluripotency markers [POU5F1 (OCT4), SOX2, NANOG, and LIN28] and embryonic stem cell (ESC)-specific genes (PODXL, DPPA5, FGF5, REX1, and LAMP1) and showed strong levels of alkaline phosphatase expression. In vitro differentiation by formation of embryoid bodies and by directed differentiation generated cell derivatives of all 3 germ layers as confirmed by mRNA and protein expression. In vivo, the ciPSCs created solid tumors, which failed to reach epithelial structure formation, but expressed markers for all 3 germ layers. Array comparative genomic hybridization and chromosomal fluorescence in situ hybridization analyses revealed that while retroviral transduction per se did not result in significant DNA copy number imbalance, there was evidence for the emergence of low-level aneuploidy during prolonged culture or tumor formation. In summary, we were able to derive ciPSCs from adult fibroblasts by using 4 transcription factors. The isolated iPSCs have similar characteristics to ESCs from other species, but the exact cellular mechanisms behind their unique co-dependency on both FGF2 and LIF are still unknown.
