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 induced pluripotent stem cells (hiPSC) hold promise for regenerative therapies, though there are several safety concerns including the risk of oncogenic transformation or unwanted adverse effects associated with hiPSC or their differentiated progeny. Introduction of the inducible caspase-9 (iC9) suicide gene, which is activated by a specific chemical inducer of dimerization (CID), is one of the most appealing safety strategies for cell therapies and is currently being tested in multicenter clinical trials. Here, we show that the iC9 suicide gene with a human EF1α promoter can be introduced into hiPSC by lentiviral transduction. The transduced hiPSC maintain their pluripotency, including their capacity for unlimited self-renewal and the potential to differentiate into three germ layer tissues. Transduced hiPSC are eliminated within 24 hours of exposure to pharmacological levels of CID in vitro, with induction of apoptosis in 94-99% of the cells. Importantly, the iC9 suicide gene can eradicate tumors derived from hiPSC in vivo. In conclusion, we have developed a direct and efficient hiPSC killing system that provides a necessary safety mechanism for therapies using hiPSC. We believe that our iC9 suicide gene will be of value in clinical applications of hiPSC-based therapy.
