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

Differentiation of embryonic stem cells (ESCs) into insulin-producing cells for cell replacement therapy of diabetes mellitus comprises the stepwise recapitulation of in vivo developmental stages of pancreatic organogenesis in an in vitro differentiation protocol. The chemical compounds IDE-1 and (-)-indolactam-V can be used to direct mouse and human ESCs through these stages to form definitive endoderm via an intermediate mesendodermal stage and finally into pancreatic endoderm. Cells of the pancreatic endoderm express the PDX1 transcription factor and contribute to all pancreatic cell types upon further in vitro or in vivo differentiation. Even though this differentiation approach is highly effective and reproducible, it generates heterogeneous populations containing PDX1-expressing pancreatic progenitors amongst other cell types. Thus, a technique to separate PDX1-expressing cells from this mixture is very desirable. Recently it has been reported that PDX1-positive pancreatic progenitors, derived from human embryonic stem cells, express the surface marker CD24. Therefore were subjected mouse and human ESCs to a small molecule differentiation approach and the expression of the surface marker CD24 was monitored in undifferentiated cells, cells committed to the definitive endoderm and cells reminiscent of the pancreatic endoderm. We observed that both mouse and human ESCs expressed CD24 in the pluripotent state, during the whole process of endoderm formation and upon further differentiation towards pancreatic endoderm. Thus CD24 is not a suitable cell surface marker for identification of PDX1-positive progenitor cells.
