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

This protocol has been designed to generate neural precursor cells (NPCs) from human embryonic stem cells (hESCs) using a physiological oxygen (O(2)) level of 3% (previously termed hypoxia) and chemically defined conditions. The first stage involves suspension culture of hESC colonies at 3% O(2), where they acquire a neuroepithelial identity over a period of 2 weeks. This timescale is comparable to that observed at 20% O(2), but survival is enhanced. Sequential application of retinoic acid and purmorphamine (PM), from day 14 to day 28, directs differentiation toward spinal motor neurons. Alternatively, addition of fibroblast growth factor-8 and PM generates midbrain dopaminergic neurons. OLIG2 (encoding oligodendrocyte lineage transcription factor 2) induction in motor neuron precursors is twofold greater than that at 20% O(2), whereas EN1 (encoding engrailed homeobox 1) expression is enhanced fivefold. NPCs (at 3% O(2)) can be differentiated into all three neural lineages, and such cultures can be maintained long term in the absence of neurotrophins. The ability to generate defined cell types at 3% O(2) should represent a significant advancement for in vitro disease modeling and potentially for cell-based therapies.
