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

The potential applications of human embryonic stem cells (hESCs) in regenerative medicine and developmental research have made stem cell biology one of the most fascinating and rapidly expanding fields of biomedicine. The first clinical trial of hESCs in humans has begun, and the field of stem cell therapy has just entered a new era. Here, we report seven hESC lines (SEES-1, -2, -3, -4, -5, -6, and -7). Four of them were derived and maintained on irradiated human mesenchymal stem cells (hMSCs) grown in xenogeneic-free defined media and substrate. Xenogeneic-free hMSCs isolated from the subcutaneous tissue of extra fingers from individuals with polydactyly showed appropriate potentials as feeder layers in the pluripotency and growth of hESCs. In this report, we describe a comprehensive characterization of these newly derived SEES cell lines. In addition, we developed a scalable culture system for hESCs having high biological safety by using gamma-irradiated serum replacement and pharmaceutical-grade recombinant basic fibroblast growth factor (bFGF, also known as trafermin). This is first report describing the maintenance of hESC pluripotency using pharmaceutical-grade human recombinant bFGF (trafermin) and gamma-irradiated serum replacement. Our defined medium system provides a path to scalability in Good Manufacturing Practice (GMP) settings for the generation of clinically relevant cell types from pluripotent cells for therapeutic applications.
