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

We previously established a two-step protocol for differentiation of human pluripotent stem cells (hPSCs) into trophoblasts, using a StemPro-based minimal medium (EMIM) with bone morphogenetic protein-4 (BMP4). This protocol was suboptimal, resulting in induction of mixed mesoderm and trophoblast markers. Furthermore, adapting hPSCs to StemPro has proven difficult, and prolonged culture in this medium has been shown to promote genomic instability. Therefore, we moved on to the use of new media, including E8, and most recently, StemFlex, for rapid adaptation from feeder to non-feeder conditions. In the new protocol, we have incorporated the WNT inhibitor IWP2 into the first step, resulting in uniform differentiation of hPSCs into cytotrophoblast (CTB)-like cells, without induction of the mesoderm lineage. We also show that, at the end of the second step, there are distinct populations of terminally differentiated multinucleated human chorionic gonadotropin (hCG)-producing syncytiotrophoblast (STB) and HLAG
