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

Keeping neural stem cells under proliferation, followed by terminal differentiation, can substantially increase the number of neurons generated. With regard to the usability of proliferating neurospheres (NSPHs) cultures, adherent induction protocols have not yet been studied in comparison to embryoid body (EB)-based protocols. To compare these proctocols, neural induction of human induced pluripotent stem cells was performed by dual SMAD inhibition under both adherent and free-floating EB culture conditions. After 10 days, we transferred cells to low-attachment culture plates and proliferated them as free-floating neurospheres. RNA was collected, transcribed to cDNA and analyzed for sonic hedgehog expression that plays an important role during proliferation process. NSPHs were analyzed by immunofluorescence imaging directly and upon continued differentiation. The EB-based approach yielded in higher numbers of cells expressing the neural stem cell marker Nestin, and showed in contrast to the adherent induction protocol increased expression levels of sonic hedgehog. Although improvements to culture consistency and reliability are desirable, the EB-based protocol appears to be superior to the adherent protocol for both, the proliferation and differentiation capacity.
